Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies
	Consolidation and Basis of Presentation:    The consolidated financial statements include the accounts of the Company and all of its majority-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated upon consolidation. The Company does not have off-balance sheet arrangements or financings with unconsolidated entities or other persons. In the ordinary course of business, the Company leases certain real properties owned by related parties as described in Note 12. Transactions with related parties are in the ordinary course of business and are not material to the Company’s financial position, results of operations or cash flows. In December 2014, the Company purchased real estate owned by a company owned by the Chairman and Chief Executive Officer of the Company for cash of $1.8 million. The transaction is included in the capital expenditures of the cash flow statement.
	Accounting Estimates:    The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
	Cash Equivalents:    The Company considers all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents.
	Inventories:    Inventories are stated at the lower of first-in, first-out (“FIFO”) cost or market value.
	Major Classes of Inventories	December 31, 2014			December 31, 2013
		(In millions)
	Finished goods	$	146		$	124.1
	Work in process	19.8			36
	Raw materials and supplies	72.6			61.3
	Inventories, net	$	238.4		$	221.4
	Other inventory items
	Inventory reserves	$	29.9		$	28.4
	Consigned Inventory	$	7.8		$	6.6
	Property, Plant and Equipment:    Property, plant and equipment are carried at cost. Additions and associated interest costs are capitalized and expenditures for repairs and maintenance are charged to operations. Depreciation of fixed assets is computed principally by the straight-line method based on the estimated useful lives of the assets ranging from five to 50 years for buildings, and one to 20 years for machinery and equipment.
	The following table summarizes property, plant and equipment at December 31, 2014 and December 31, 2013:
		December 31,			December 31,
		2014			2013
	Property, plant and equipment:
	Land and land improvements	$	7.1		$	6.5
	Buildings	68.4			58.2
	Machinery and equipment	293.5			261.5
	Total property, plant and equipment	369			326.2
	Less accumulated depreciation	227.9			210.8
	Net property, plant and equipment	$	141.1		$	115.4
	Impairment of Long-Lived Assets:    We assess the recoverability of long-lived assets (excluding goodwill) and identifiable acquired intangible assets with finite useful lives, whenever events or changes in circumstances indicate that we may not be able to recover the assets’ carrying amount. We measure the recoverability of assets to be held and used by a comparison of the carrying amount of the asset to the expected net future undiscounted cash flows to be generated by that asset, or, for identifiable intangibles with finite useful lives, by determining whether the amortization of the intangible asset balance over its remaining life can be recovered through undiscounted future cash flows. The amount of impairment of identifiable intangible assets with finite useful lives, if any, to be recognized is measured based on projected discounted future cash flows. We measure the amount of impairment of other long-lived assets (excluding goodwill) as the amount by which the carrying value of the asset exceeds the fair market value of the asset, which is generally determined, based on projected discounted future cash flows or appraised values. We classify long-lived assets to be disposed of other than by sale as held and used until they are disposed.
	Goodwill and Indefinite-Lived Assets:    In accordance with Accounting Standards Codification (“ASC”) 350, “Intangibles — Goodwill and Other” (“ASC 350”), the Company does not amortize goodwill or indefinite-lived intangible assets recorded in connection with business acquisitions.
	Goodwill and indefinite life intangible assets are tested annually for impairment as of October 1, or whenever events or changes in circumstances indicate there may be a possible permanent loss of value in accordance with ASC 350.
	Goodwill is tested for impairment at the reporting unit level and is based on the net assets for each reporting unit, including goodwill and intangible assets, compared to the fair value. In accordance with Accounting Standard Update (“ASU”) 2011-08, an entity has the option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If, after assessing the totality of events or circumstances, an entity determines it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, then performing the two-step quantitative impairment test is unnecessary.
	In assessing the qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount, we identify and assess relevant drivers of fair value and events and circumstances that may impact the fair value and the carrying amount of the reporting unit. The identification of relevant events and circumstances and how these may impact a reporting unit’s fair value or carrying amount involve significant judgments and assumptions. The judgments and assumptions include the identification of macroeconomic conditions, industry and market considerations, cost factors, overall financial performance, Company-specific events and share price trends, and the assessment of whether each relevant factor will impact the impairment test positively or negatively and the magnitude of any such impact.
	If our qualitative assessment concludes that it is more likely than not that impairment exists then a quantitative assessment is required. In a quantitative assessment, we use an income approach and other valuation techniques to estimate the fair value of our reporting units. Absent an indication of fair value from a potential buyer or similar specific transactions, we believe that using this methodology provides reasonable estimates of a reporting unit’s fair value. The income approach is based on projected future debt-free cash flow that is discounted to present value using factors that consider the timing and risk of the future cash flows. We believe that this approach is appropriate because it provides a fair value estimate based upon the reporting unit’s expected long-term operating and cash flow performance. This approach also mitigates most of the impact of cyclical downturns that occur in the reporting unit’s industry. The income approach is based on a reporting unit’s projection of operating results and cash flows that is discounted using a weighted-average cost of capital. The projection is based upon our best estimates of projected economic and market conditions over the related period including growth rates, estimates of future expected changes in operating margins and cash expenditures. Other significant estimates and assumptions include terminal value growth rates, terminal value margin rates, future capital expenditures and changes in future working capital requirements based on management projections. There are inherent uncertainties, however, related to these factors and to our judgment in applying them to this analysis. Nonetheless, we believe that this method provides a reasonable approach to estimate the fair value of our reporting units.
	The Company completed its annual goodwill impairment test for each year presented and confirmed no reporting unit was at risk of failing the impairment test for any periods presented herein.
	Indefinite life intangible assets are tested annually for impairment as of October 1, or whenever events or changes in circumstances indicate there may be a possible permanent loss of value in accordance with ASC 350. In accordance with ASU 2011-08, an entity may elect to first assess qualitative factors to determine whether it is more likely than not that the fair value of the indefinite-lived intangible is less than its carrying value. The Company completed its annual indefinite-lived intangible impairment assessment. As a result of this analysis, we concluded that no impairment existed.
	Fair Values of Financial Instruments: Certain financial instruments are required to be recorded at fair value. The Company measures financial assets and liabilities at fair value in three levels of inputs. The three-tier fair value hierarchy, which prioritizes the inputs used in the valuation methodologies, is:
	Level 1 — Valuations based on quoted prices for identical assets and liabilities in active markets.
	Level 2 — Valuations based on observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data.
	Level 3 — Valuations based on unobservable inputs reflecting our own assumptions, consistent with reasonably available assumptions made by other market participants. These valuations require significant judgment.
	Changes in assumptions or estimation methods could affect the fair value estimates; however, we do not believe any such changes would have a material impact on our financial condition, results of operations or cash flows. The carrying value of cash and cash equivalents, accounts receivable, accounts payable and borrowings under the Credit Agreement (as defined in Note 9) approximate fair value at December 31, 2014 and December 31, 2013. The fair values of long-term debt and pension plan assets are disclosed in Note 9 and Note 13, respectively.
	The Company has not changed its valuation techniques for measuring fair value during 2014, and there were no transfers between levels during the periods presented.
	Income Taxes:    The Company accounts for income taxes under the asset and liability method, whereby deferred tax assets and liabilities are determined based on temporary differences between the financial reporting and the tax bases of assets and liabilities and are measured using the current enacted tax rates. In determining these amounts, management determined the probability of realizing deferred tax assets, taking into consideration factors including historical operating results, cumulative earnings and losses, expectations of future earnings, taxable income and the extended period of time over which the postretirement benefits will be paid and accordingly records valuation allowances if, based on the weight of available evidence, it is more likely than not that some portion or all of our deferred tax assets will not be realized as required by ASC 740, “Income Taxes” (“ASC 740”).
	Stock-Based Compensation:    The Company follows the provisions of ASC 718, “Compensation — Stock Compensation” (“ASC 718”), which requires all share-based payments to employees, including grants of employee stock options, to be recognized in the income statement based on their fair values. Compensation expense for awards with service conditions only that are subject to graded vesting is recognized on a straight-line basis over the term of the vesting period.
	Under the provisions of the Company’s 1998 Long-Term Incentive Plan, as amended (“1998 Plan”), which is administered by the Compensation Committee of the Company’s Board of Directors, incentive stock options, non-statutory stock options, stock appreciation rights (“SARs”), restricted share units, performance shares or stock awards may be awarded to directors and all employees of the Company and its subsidiaries. Stock options will be exercisable in whole or in installments as may be determined provided that no options will be exercisable more than ten years from date of grant. The exercise price will be the fair market value at the date of grant. The aggregate number of shares of the Company’s common stock that may be awarded under the 1998 Plan is 3,700,000, all of which may be incentive stock options. No more than 500,000 shares shall be the subject of awards to any individual participant in any one calendar year.
	Revenue Recognition:    The Company recognizes revenue, other than from long-term contracts, when title is transferred to the customer, typically upon shipment. Revenue from long-term contracts (approximately 8% of consolidated revenue) is accounted for under the percentage of completion method, and recognized on the basis of the percentage each contract’s cost to date bears to the total estimated contract cost. Revenue earned on contracts in process that are in excess of billings, is classified in unbilled contract revenues in the accompanying consolidated balance sheets. Billings that are in excess of revenues earned on contracts in process are classified in accrued expenses in the accompanying balance sheets.
	Cost of Sales: Cost of sales is primarily comprised of direct materials and supplies consumed in the manufacture of product, as well as manufacturing labor, depreciation expense and direct overhead expense necessary to acquire and convert the purchased materials and supplies into finished product. Cost of sales also includes the cost to distribute products to customers, inbound freight costs, internal transfer costs, warehousing costs and other shipping and handling activity.
	Shipping and Handling Costs:    All shipping and handling costs are included in cost of sales in the Consolidated Statements of Income.
	Accounts Receivable and Allowance for Doubtful Accounts:    Accounts receivable are recorded at net realizable value. Accounts receivable are reduced by an allowance for amounts that may become uncollectable in the future. The Company’s policy is to identify and reserve for specific collectability concerns based on customers’ financial condition and payment history. During 2014 and 2013, we sold approximately $95.0 million and $75.4 million, respectively, of accounts receivable to mitigate accounts receivable concentration risk and to provide additional financing capacity. In compliance with ASC 860, “Transfers and Servicing”, sales of accounts receivable are reflected as a reduction of accounts receivable in the Consolidated Balance Sheets and the proceeds are included in the cash flows from operating activities in the Consolidated Statements of Cash flows. In 2014 and 2013, an expense in the amount of $0.5 million and $0.4 million, respectively, related to the discount on sale of accounts receivable is recorded in the Consolidated Statements of Income.
	Concentration of Credit Risk:    The Company sells its products to customers in diversified industries. The Company performs ongoing credit evaluations of its customers’ financial condition but does not require collateral to support customer receivables. The Company establishes an allowance for doubtful accounts based upon factors surrounding the credit risk of specific customers, historical trends and other information. As of December 31, 2014, the Company had uncollateralized receivables with six customers in the automotive industry, each with several locations, aggregating $37.7 million, which represented approximately 18% of the Company’s trade accounts receivable. During 2014, sales to these customers amounted to approximately $252.6 million, which represented approximately 18% of the Company’s net sales.
	Environmental:    The Company accrues environmental costs related to existing conditions resulting from past or current operations and from which no current or future benefit is discernible. Costs that extend the life of the related property or mitigate or prevent future environmental contamination are capitalized. The Company records a liability when environmental assessments and/or remedial efforts are probable and can be reasonably estimated. The estimated liability of the Company is not reduced for possible recoveries from insurance carriers.
	Legal Contingencies:     We are involved in a variety of claims, suits, investigations and administrative proceedings with respect to commercial, premises liability, product liability, employment and environmental matters arising from the ordinary course of business. We accrue reserves for legal contingencies, on an undiscounted basis, when it is probable that we have incurred a liability and we can reasonably estimate an amount. When a single amount cannot be reasonably estimated, but the cost can be estimated within a range, we accrue the minimum amount in the range. Based upon facts and information currently available, we believe the amounts reserved are adequate for such pending matters. We monitor the development of legal proceedings on a regular basis and will adjust our reserves when, and to the extent, additional information becomes available.
	Foreign Currency Translation:    The functional currency for a majority of subsidiaries outside the United States is the local currency. Financial statements for these subsidiaries are translated into U.S. dollars at year-end exchange rates for assets and liabilities and weighted-average exchange rates for revenues and expenses. The resulting translation adjustments are recorded in accumulated comprehensive income (loss) in shareholders’ equity.

	Recent Accounting Pronouncements Not Yet Adopted
	In April 2014, the FASB issued ASU 2014-08, “Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity,” which raises the threshold for disposals to qualify as discontinued operations and requires new disclosures for discontinued operations and for individually material disposal transactions that do not meet the definition of a discontinued operation. The ASU is effective prospectively for reporting periods beginning with the first quarter of 2015. Early adoption is permitted for disposals that have not been previously reported in the financial statements. We believe the adoption of this ASU will have an insignificant effect on our consolidated financial statement as it only applies to future disposals.
	In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers (Topic 606),” which was the result of a joint project by the FASB and International Accounting Standards Board to clarify the principles for recognizing revenue and to develop a common revenue standard for U.S. generally accepted accounting principles and International Financial Reporting Standards. The issuance of a comprehensive and converged standard on revenue recognition is expected to enable financial statement users to better understand and consistently analyze an entity’s revenue across industries, transactions, and geographies. The ASU will require additional disclosures to help financial statement users better understand the nature, amount, timing, and potential uncertainty of the revenue that is recognized. The ASU is effective for annual reporting periods beginning after December 15, 2016, and will require either retrospective application to each prior reporting period presented or retrospective application with the cumulative effect of initially applying the standard recognized at the date of adoption. The Company is currently evaluating the impact of adopting this guidance.
Reclassification: Certain amounts in the prior years' financial statements have been reclassified to conform to the current year presentation.

Business Combinations [Abstract]
Acquisitions	Acquisitions
	In December 2014, the Company acquired all the outstanding capital stock of Saet S.p.A. (“Saet”) for $22.1 million in cash. Saet is a leader in the design, manufacturing and testing of induction heating equipment and heat treat solutions through its locations in Italy, China, India and Tennessee. The financial results of Saet are included in the Company's Engineered Products segment from the date of acquisition. Saet's sales for the year ended December 31, 2013 were approximately $35.9 million.
	The acquisition of Saet was accounted for under the acquisition method of accounting. The entire purchase price allocation for Saet is preliminary. At December 31, 2014, the fair values of the assets acquired and liabilities assumed have been preliminarily estimated based on their carrying values and the excess consideration of $23.2 million has been preliminarily recorded as goodwill due to the proximity of the acquisition to the year-end date and pending finalization of the fair value. These preliminary estimates will be revised during the measurement period in 2015 as all pertinent information regarding finalization of the third-party valuations for inventories, intangible assets, goodwill, tangible assets, other liabilities and deferred income tax assets and liabilities acquired are fully evaluated by the Company.
	In October 2014, the Company acquired all the outstanding capital stock of Autoform Tool and Manufacturing (“Autoform”) for a total purchase consideration of $48.9 million in cash. The acquisition was funded from borrowings under the revolving credit facility provided by the Credit Agreement. Autoform is a supplier of high end pressure fuel lines used in gasoline direct injection systems across a large number of engine platforms. Autoform's production facilities are located in Indiana. The financial results of Autoform are included in the Company's Assembly Components segment from the date of acquisition. Autoform generated approximately $36.8 million of revenue for the year ended December 31, 2013.
	In June 2014, the Company acquired all the outstanding capital stock of Apollo Aerospace Group (“Apollo”) for $6.5 million, net of cash acquired. Apollo is a supply chain management company providing Class C production components and supply chain solutions to aerospace customers worldwide. Apollo generated net sales of approximately $8.1 million for its fiscal year ended March 31, 2014. The financial results of Apollo are included in the Company's Supply Technologies segment from the date of acquisition.
	The acquisitions of Autoform and Apollo were accounted for under the acquisition method of accounting. The purchase price allocations were preliminary as of December 31, 2014. The Apollo purchase agreement provides payment of contingent consideration of approximately $2.4 million based on achievement of certain EBITDA targets over two years. The fair value of the earn-out was approximately $1.1 million at the date of the acquisition for a total purchase consideration of $6.5 million. On the acquisition date, a liability was recognized for the estimate of the acquisition date fair value of the earn-out. Any change in the fair value of the earn-out subsequent to the acquisition date will be recognized in selling, general and administrative expenses. Management's valuation of the fair value of tangible and intangible assets acquired and liabilities assumed for these acquisitions is based on estimates and assumptions. The purchase price allocation relating to these acquisitions is subject to further adjustment until all pertinent information regarding finalization of the appraisals for intangibles, goodwill and deferred income tax assets and liabilities acquired are fully evaluated by the Company and independent valuations are complete. Revisions to these estimates as fair values are finalized will be reflected in the financial statements throughout the measurement period. Based on the preliminary purchase price allocation for these acquisitions, goodwill of $5.7 million was recorded.
	In November 2013, the Company acquired all the outstanding capital stock of QEF Global Limited (“QEF”). QEF is a provider of supply chain management solutions with four locations throughout Ireland, Scotland and England.

	On April 7, 2011, the Company completed the sale of $250.0 million in the aggregate principal amount of 8.125% senior notes due 2021 (the "Notes"). The Notes bear an interest rate of 8.125% per annum, payable semi-annually in arrears on April 1 and October 1 of each year. The Notes mature on April 1, 2021. The Company is a party to a credit and security agreement, dated November 5, 2003, as amended (the “Credit Agreement”), with a group of banks, under which it may borrow or issue standby letters of credit or commercial letters of credit.
	On July 31, 2014, the Company entered into a sixth amendment and restatement of the credit agreement (the “Amended Credit Agreement”). The Amended Credit Agreement, among other things, increases the revolving credit facility to $230.0 million, provides a term loan for $16.1 million and extends the maturity date of the borrowings under the Amended Credit Agreement to July 31, 2019. The revolving credit facility includes a Canadian sub-limit of $15.0 million and a European sub-limit of $10.0 million (which may be increased to $25.0 million) for borrowings in those locations.
	At the Company’s election, domestic amounts borrowed under the revolving credit facility may be borrowed at either:
	•LIBOR plus 1.5% to 2.5%; or
	•the bank’s prime lending rate minus 0.25% to 1.25%.
	At the Company's election, amounts borrowed under the term loan may be borrowed at either:
	•LIBOR plus 2.0% to 3.0%; or
	•the bank’s prime lending rate minus 0.75% to plus 0.25%.
	The LIBOR-based interest rate is dependent on the Company’s debt service coverage ratio, as defined in the Amended Credit Agreement.
	Amounts borrowed under the Canadian revolving credit facility provided by the Amended Credit Agreement may be borrowed at either:

	•the Canadian prime lending rate plus 0.0% to 1.0%; or
	•the US base rate plus 0.0% to 1.0%.
	Under the Amended Credit Agreement, a detailed borrowing base formula provides borrowing availability to the Company based on percentages of eligible accounts receivable and inventory. The term loan is amortized based on a seven-year schedule with the balance due at maturity (July 31, 2019). The Amended Credit Agreement also reduced the commitment fee for the revolving credit facility. Additionally, the Company has the option, pursuant to the Amended Credit Agreement, to increase the availability under the revolving credit facility by $50.0 million.
	The Amended Credit Agreement was further amended in accordance with Amendment No. 1 to the Amended Credit Agreement, dated October 24, 2014 (the “Amendment”). The Amendment:
	•	increases the revolving credit facility from $230.0 million to $250.0 million;
	•	increases the inventory advance rate from 50% to 60%, reducing back to 50% on a pro-rata quarterly basis over 36 months commencing April 1, 2015;
	•	reloads the term loan up to $35.0 million from $15.5 million, of which $28.8 million has been borrowed and is outstanding as of December 31, 2014;
	•	increases the Canadian sub-limit up to $25.0 million from $15.0 million;
	•	increases the European sub-limit up to $25.0 million from $10.0 million; and
	•	provides minor pricing adjustments including pricing the first $22.0 million drawn on the revolver at LIBOR + 3.50%, reducing automatically on a pro-rata quarterly basis over 36 months commencing April 1, 2015.
	At December 31, 2014, in addition to amounts borrowed under the revolving credit facility, there was $20.5 million outstanding for standby letters of credit.
	At December 31, 2014, the Company had approximately $55.4 million of unused borrowing capacity under the revolving credit facility.
	The following table represents fair value information of the Notes, classified as Level 1, at December 31, 2014 and December 31, 2013. The fair value was estimated using quoted market prices.

	At December 31, 2014, the Company has state and foreign net operating loss carryforwards for income tax purposes. The foreign net operating loss carryforward is $16.4 million, of which $1.9 million expires between 2015 and 2024 and the remainder has no expiration date. The Company also has a tax benefit from a state net operating loss carryforward of $2.9 million that expires between 2015 and 2033. The Company also has a foreign capital loss carryforward of $0.6 million that has no expiration date.
	The Company is subject to taxation in the U.S. and various state and foreign jurisdictions. The Company’s tax years for 2011 through 2014 remain open for examination by the U.S. and various state and foreign taxing authorities.
	As of December 31, 2014 and 2013, the Company was not in a cumulative three-year loss position and it was determined that it was more likely than not that its U.S. deferred tax assets will be realized. As of December 31, 2014, the Company reversed a valuation allowance of $1.3 million against its state net operating loss carryforward. As of December 31, 2014 and 2013, the Company recorded valuation allowances of $6.9 million and $1.2 million, respectively, against certain foreign net deferred tax assets. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income (including reversals of deferred tax liabilities). The Company reviews all valuation allowances related to deferred tax assets and will reverse these valuation allowances, partially or totally, when appropriate under ASC 740.
	A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows:
		2014			2013			2012
		(In millions)
Unrecognized Tax Benefit — January 1,	$	5.9		$	6.1		$	6

Lapse of Statute of Limitations	—			—			(0.1		)
Unrecognized Tax Benefit — December 31,	$	6.5		$	5.9		$	6.1
The total amount of unrecognized tax benefits that, if recognized, would affect the effective tax rate is $5.4 million at December 31, 2014 and $4.7 million at December 31, 2013. The Company recognizes accrued interest and penalties related to unrecognized tax benefits in income tax expense. During the year ended December 31, 2014 and 2013, the Company recognized approximately $0.3 million and $0.7 million, respectively, in net interest and penalties. The Company had approximately $1.7 million and $1.4 million for the payment of interest and penalties accrued at December 31, 2014 and 2013, respectively. The Company does not expect that the unrecognized tax benefit will change significantly within the next twelve months.
Deferred taxes have not been provided on approximately $90.2 million of undistributed earnings of the Company’s foreign subsidiaries as it is the Company’s policy and intent to permanently reinvest such earnings. The Company has determined that it is not practicable to determine the unrecognized tax liability on such undistributed earnings.

Commitments and Contingencies Disclosure [Abstract]
Commitments, Contingencies and Litigation Judgment	Commitments, Contingencies and Litigation Judgment
	The Company is subject to various pending and threatened legal proceedings arising in the ordinary course of business. Although the Company cannot precisely predict the amount of any liability that may ultimately arise with respect to any of these matters, the Company records provisions when it considers the liability probable and reasonably estimable. Our provisions are based on historical experience and legal advice, reviewed quarterly and adjusted according to developments. Estimating probable losses requires the analysis of multiple forecasted factors that often depend on judgments about potential actions by third parties, such as regulators, courts, and state and federal legislatures. Changes in the amounts of our loss provisions, which can be material, affect our financial condition. Due to the inherent uncertainties in the process undertaken to estimate potential losses, we are unable to estimate an additional range of loss in excess of our accruals. While it is reasonably possible that such excess liabilities, if they were to occur, could be material to operating results in any given quarter or year of their recognition, we do not believe that it is reasonably possible that such excess liabilities would have a material adverse effect on our long-term results of operations, liquidity or consolidated financial position.
	Our subsidiaries are involved in a number of contractual and warranty related disputes. At this time, we cannot reasonably determine the probability of a loss, and the timing and amount of loss, if any, cannot be reasonably estimated. We believe that appropriate liabilities for these contingencies have been recorded; however, actual results may differ materially from our estimates.
	IPSCO Tubulars Inc. d/b/a TMK IPSCO sued Ajax Tocco Magnethermic Corporation ("ATM"), a subsidiary of Park-Ohio Holdings Corporation, in the United States District Court for the Eastern District of Arkansas claiming that equipment supplied by ATM for heat treating certain steel pipe at IPSCO’s Blytheville, Arkansas facility did not perform as required by the contract. The complaint alleged causes of action for breach of contract, gross negligence, and constructive fraud.  IPSCO sought approximately $10 million in damages plus an unspecified amount of punitive damages.  ATM denied the allegations.  ATM subsequently obtained summary judgment on the constructive fraud claim, which was dismissed by the district court prior to trial.  The remaining claims were the subject of a bench trial that occurred in May 2013.  After IPSCO presented its case, the district court entered partial judgment in favor of ATM, dismissing the gross negligence claim, a portion of the breach of contract claim, and any claim for punitive damages.  The trial proceeded with respect to the remainder of IPSCO’s claim for breach of contract.  In September 2013, the district court issued a judgment in favor of IPSCO in the amount of $5.2 million. IPSCO subsequently filed a motion seeking to recover $3.8 million in attorneys’ fees and costs.  The district court reserved ruling on that issue pending an appeal.  In October 2013, ATM filed an appeal with the U.S. Court of Appeals for the Eighth Circuit seeking reversal of the judgment in favor of IPSCO.  In November 2013, IPSCO filed a cross-appeal seeking reversal of the dismissal of its claims for gross negligence and punitive damages.  The Eighth Circuit issued an opinion in March 2015 affirming in part, reversing in part, and remanding the case.  It affirmed the district court's determination that ATM was liable for breach of contract.  It also affirmed the district court's dismissal of IPSCO's claims for gross negligence and punitive damages.  However, the Eighth Circuit reversed nearly all of the damages awarded by the district court and remanded for further findings on the issue of damages, including whether consequential damages are barred under the express language of the contract.  Because IPSCO did not appeal the award of $5.2 million in its favor, those damages may be decreased, but cannot be increased, on remand.  Because IPSCO did not appeal the award of $5.2 million in its favor, those damages may be decreased, but cannot be increased, on remand.  IPSCO's motion to recover attorneys' fees and costs is stayed pending the outcome of the proceedings on remand.
	In August 2013, the Company received a subpoena from the staff of the SEC in connection with the staff’s investigation of a third party. At that time, the Company also learned that the Department of Justice (“DOJ”) is conducting a criminal investigation of the third party. In connection with its initial response to the staff’s subpoena, the Company disclosed to the staff of the SEC that, in November 2007, the third party participated in a payment on behalf of the Company to a foreign tax official that implicates the Foreign Corrupt Practices Act (“FCPA”).
	The Board of Directors of the Company has formed a special committee to review the Company’s transactions with the third party and to make any recommendations to the Board of Directors with respect thereto.
	The Company intends to cooperate fully with the SEC and the DOJ in connection with their investigations of the third party and with the SEC in light of the Company’s disclosure. The Company is unable to predict the outcome or impact of the special committee’s investigation or the length, scope or results of the SEC’s review or the impact on its results of operations.

	Certain of the Company’s leases are with related parties at an annual rental expense of approximately $2.3 million. Transactions with related parties are in the ordinary course of business and are not material to the Company’s financial position, results of operations or cash flows.
	During the years ended December 31, 2013 and 2012, we entered into sales leaseback transactions for certain equipment. No gains or losses resulted from these transactions and the leases are being accounted for as operating leases.

Pensions and Postretirement Benefits	Pensions and Postretirement Benefits
	The Company and its subsidiaries have pension plans, principally noncontributory defined benefit or noncontributory defined contribution plans, covering substantially all employees. In addition, the Company has an unfunded postretirement benefit plan. In April 2011, the Company amended one of its plans to cover most U.S. employees not covered by collective bargaining agreements using a cash balance formula, which increased the 2011 benefit obligation by approximately $1.1 million. Under a cash balance formula, a plan participant accumulates a retirement benefit consisting of pay credits that are based upon a percentage of current eligible earnings and current interest credits. For the remaining defined benefit plans, benefits are based on the employee’s years of service. For the defined contribution plans, the costs charged to operations and the amount funded are based upon a percentage of the covered employees’ compensation.
	The following tables set forth the change in benefit obligation, plan assets, funded status and amounts recognized in the consolidated balance sheet for the defined benefit pension and postretirement benefit plans as of December 31, 2014 and 2013:

In determining its expected return on plan assets assumption for the year ended December 31, 2014, the Company considered historical experience, its asset allocation, expected future long-term rates of return for each major asset class, and an assumed long-term inflation rate. Based on these factors, the Company derived an expected return on plan assets for the year ended December 31, 2014 of 8.25%. This assumption was supported by the asset return generation model, which projected future asset returns using simulation and asset class correlation.

The Company expects to have no contributions to its defined benefit plans in 2015.
In January 2008, a Supplemental Executive Retirement Plan (“SERP”) for the Company’s Chairman of the Board of Directors and Chief Executive Officer (“CEO”) was approved by the Compensation Committee of the Board of Directors of the Company. The SERP provides an annual supplemental retirement benefit for up to $0.4 million upon the CEO’s termination of employment with the Company. The vested retirement benefit will be equal to a percentage of the Supplemental Pension that is equal to the ratio of the sum of his credited service with the Company prior to January 1, 2008 (up to a maximum of thirteen years), and his credited service on or after January 1, 2008 (up to a maximum of seven years) to twenty years of credited service. In the event of a change in control before the CEO’s termination of employment, he will receive 100% of the Supplemental Pension. The Company recorded an expense of $0.5 million in 2014, 2013 and 2012 related to the SERP. Additionally, a non-qualified defined contribution retirement benefit was also approved in which the Company will credit $0.1 million quarterly ($0.4 million annually) for a seven-year period to an account in which the CEO will always be 100% vested. The seven year period began on March 31, 2008.

Summary_of_Significant_Account1

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2014
Accounting Policies [Abstract]
Consolidation and Basis of Presentation	Consolidation and Basis of Presentation:    The consolidated financial statements include the accounts of the Company and all of its majority-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated upon consolidation. The Company does not have off-balance sheet arrangements or financings with unconsolidated entities or other persons. In the ordinary course of business, the Company leases certain real properties owned by related parties as described in Note 12. Transactions with related parties are in the ordinary course of business and are not material to the Company’s financial position, results of operations or cash flows. In December 2014, the Company purchased real estate owned by a company owned by the Chairman and Chief Executive Officer of the Company for cash of $1.8 million. The transaction is included in the capital expenditures of the cash flow statement.
Accounting Estimates	Accounting Estimates:    The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Cash Equivalents	Cash Equivalents:    The Company considers all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents.
Inventories	Inventories:    Inventories are stated at the lower of first-in, first-out (“FIFO”) cost or market value.
Property, Plant and Equipment	Property, Plant and Equipment:    Property, plant and equipment are carried at cost. Additions and associated interest costs are capitalized and expenditures for repairs and maintenance are charged to operations. Depreciation of fixed assets is computed principally by the straight-line method based on the estimated useful lives of the assets ranging from five to 50 years for buildings, and one to 20 years for machinery and equipment.
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets:    We assess the recoverability of long-lived assets (excluding goodwill) and identifiable acquired intangible assets with finite useful lives, whenever events or changes in circumstances indicate that we may not be able to recover the assets’ carrying amount. We measure the recoverability of assets to be held and used by a comparison of the carrying amount of the asset to the expected net future undiscounted cash flows to be generated by that asset, or, for identifiable intangibles with finite useful lives, by determining whether the amortization of the intangible asset balance over its remaining life can be recovered through undiscounted future cash flows. The amount of impairment of identifiable intangible assets with finite useful lives, if any, to be recognized is measured based on projected discounted future cash flows. We measure the amount of impairment of other long-lived assets (excluding goodwill) as the amount by which the carrying value of the asset exceeds the fair market value of the asset, which is generally determined, based on projected discounted future cash flows or appraised values. We classify long-lived assets to be disposed of other than by sale as held and used until they are disposed.
Goodwill and Indefinite-Lived Assets	Goodwill and Indefinite-Lived Assets:    In accordance with Accounting Standards Codification (“ASC”) 350, “Intangibles — Goodwill and Other” (“ASC 350”), the Company does not amortize goodwill or indefinite-lived intangible assets recorded in connection with business acquisitions.
	Goodwill and indefinite life intangible assets are tested annually for impairment as of October 1, or whenever events or changes in circumstances indicate there may be a possible permanent loss of value in accordance with ASC 350.
	Goodwill is tested for impairment at the reporting unit level and is based on the net assets for each reporting unit, including goodwill and intangible assets, compared to the fair value. In accordance with Accounting Standard Update (“ASU”) 2011-08, an entity has the option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If, after assessing the totality of events or circumstances, an entity determines it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, then performing the two-step quantitative impairment test is unnecessary.
	In assessing the qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount, we identify and assess relevant drivers of fair value and events and circumstances that may impact the fair value and the carrying amount of the reporting unit. The identification of relevant events and circumstances and how these may impact a reporting unit’s fair value or carrying amount involve significant judgments and assumptions. The judgments and assumptions include the identification of macroeconomic conditions, industry and market considerations, cost factors, overall financial performance, Company-specific events and share price trends, and the assessment of whether each relevant factor will impact the impairment test positively or negatively and the magnitude of any such impact.
	If our qualitative assessment concludes that it is more likely than not that impairment exists then a quantitative assessment is required. In a quantitative assessment, we use an income approach and other valuation techniques to estimate the fair value of our reporting units. Absent an indication of fair value from a potential buyer or similar specific transactions, we believe that using this methodology provides reasonable estimates of a reporting unit’s fair value. The income approach is based on projected future debt-free cash flow that is discounted to present value using factors that consider the timing and risk of the future cash flows. We believe that this approach is appropriate because it provides a fair value estimate based upon the reporting unit’s expected long-term operating and cash flow performance. This approach also mitigates most of the impact of cyclical downturns that occur in the reporting unit’s industry. The income approach is based on a reporting unit’s projection of operating results and cash flows that is discounted using a weighted-average cost of capital. The projection is based upon our best estimates of projected economic and market conditions over the related period including growth rates, estimates of future expected changes in operating margins and cash expenditures. Other significant estimates and assumptions include terminal value growth rates, terminal value margin rates, future capital expenditures and changes in future working capital requirements based on management projections. There are inherent uncertainties, however, related to these factors and to our judgment in applying them to this analysis. Nonetheless, we believe that this method provides a reasonable approach to estimate the fair value of our reporting units.
	The Company completed its annual goodwill impairment test for each year presented and confirmed no reporting unit was at risk of failing the impairment test for any periods presented herein.
	Indefinite life intangible assets are tested annually for impairment as of October 1, or whenever events or changes in circumstances indicate there may be a possible permanent loss of value in accordance with ASC 350. In accordance with ASU 2011-08, an entity may elect to first assess qualitative factors to determine whether it is more likely than not that the fair value of the indefinite-lived intangible is less than its carrying value. The Company completed its annual indefinite-lived intangible impairment assessment. As a result of this analysis, we concluded that no impairment existed.
Fair Values of Financial Instruments	Fair Values of Financial Instruments: Certain financial instruments are required to be recorded at fair value. The Company measures financial assets and liabilities at fair value in three levels of inputs. The three-tier fair value hierarchy, which prioritizes the inputs used in the valuation methodologies, is:
	Level 1 — Valuations based on quoted prices for identical assets and liabilities in active markets.
	Level 2 — Valuations based on observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data.
	Level 3 — Valuations based on unobservable inputs reflecting our own assumptions, consistent with reasonably available assumptions made by other market participants. These valuations require significant judgment.
	Changes in assumptions or estimation methods could affect the fair value estimates; however, we do not believe any such changes would have a material impact on our financial condition, results of operations or cash flows. The carrying value of cash and cash equivalents, accounts receivable, accounts payable and borrowings under the Credit Agreement (as defined in Note 9) approximate fair value at December 31, 2014 and December 31, 2013. The fair values of long-term debt and pension plan assets are disclosed in Note 9 and Note 13, respectively.
	The Company has not changed its valuation techniques for measuring fair value during 2014, and there were no transfers between levels during the periods presented.
Income Taxes	Income Taxes:    The Company accounts for income taxes under the asset and liability method, whereby deferred tax assets and liabilities are determined based on temporary differences between the financial reporting and the tax bases of assets and liabilities and are measured using the current enacted tax rates. In determining these amounts, management determined the probability of realizing deferred tax assets, taking into consideration factors including historical operating results, cumulative earnings and losses, expectations of future earnings, taxable income and the extended period of time over which the postretirement benefits will be paid and accordingly records valuation allowances if, based on the weight of available evidence, it is more likely than not that some portion or all of our deferred tax assets will not be realized as required by ASC 740, “Income Taxes” (“ASC 740”).
Stock-Based Compensation	Stock-Based Compensation:    The Company follows the provisions of ASC 718, “Compensation — Stock Compensation” (“ASC 718”), which requires all share-based payments to employees, including grants of employee stock options, to be recognized in the income statement based on their fair values. Compensation expense for awards with service conditions only that are subject to graded vesting is recognized on a straight-line basis over the term of the vesting period.
	Under the provisions of the Company’s 1998 Long-Term Incentive Plan, as amended (“1998 Plan”), which is administered by the Compensation Committee of the Company’s Board of Directors, incentive stock options, non-statutory stock options, stock appreciation rights (“SARs”), restricted share units, performance shares or stock awards may be awarded to directors and all employees of the Company and its subsidiaries. Stock options will be exercisable in whole or in installments as may be determined provided that no options will be exercisable more than ten years from date of grant. The exercise price will be the fair market value at the date of grant. The aggregate number of shares of the Company’s common stock that may be awarded under the 1998 Plan is 3,700,000, all of which may be incentive stock options. No more than 500,000 shares shall be the subject of awards to any individual participant in any one calendar year.
Revenue Recognition	Revenue Recognition:    The Company recognizes revenue, other than from long-term contracts, when title is transferred to the customer, typically upon shipment. Revenue from long-term contracts (approximately 8% of consolidated revenue) is accounted for under the percentage of completion method, and recognized on the basis of the percentage each contract’s cost to date bears to the total estimated contract cost. Revenue earned on contracts in process that are in excess of billings, is classified in unbilled contract revenues in the accompanying consolidated balance sheets. Billings that are in excess of revenues earned on contracts in process are classified in accrued expenses in the accompanying balance sheets.
Cost of Sales	Cost of Sales: Cost of sales is primarily comprised of direct materials and supplies consumed in the manufacture of product, as well as manufacturing labor, depreciation expense and direct overhead expense necessary to acquire and convert the purchased materials and supplies into finished product. Cost of sales also includes the cost to distribute products to customers, inbound freight costs, internal transfer costs, warehousing costs and other shipping and handling activity.
Shipping and Handling Costs	Shipping and Handling Costs:    All shipping and handling costs are included in cost of sales in the Consolidated Statements of Income.
Accounts Receivable and Allowance for Doubtful Accounts	Accounts Receivable and Allowance for Doubtful Accounts:    Accounts receivable are recorded at net realizable value. Accounts receivable are reduced by an allowance for amounts that may become uncollectable in the future. The Company’s policy is to identify and reserve for specific collectability concerns based on customers’ financial condition and payment history. During 2014 and 2013, we sold approximately $95.0 million and $75.4 million, respectively, of accounts receivable to mitigate accounts receivable concentration risk and to provide additional financing capacity. In compliance with ASC 860, “Transfers and Servicing”, sales of accounts receivable are reflected as a reduction of accounts receivable in the Consolidated Balance Sheets and the proceeds are included in the cash flows from operating activities in the Consolidated Statements of Cash flows. In 2014 and 2013, an expense in the amount of $0.5 million and $0.4 million, respectively, related to the discount on sale of accounts receivable is recorded in the Consolidated Statements of Income.
Concentration of Credit Risk	Concentration of Credit Risk:    The Company sells its products to customers in diversified industries. The Company performs ongoing credit evaluations of its customers’ financial condition but does not require collateral to support customer receivables. The Company establishes an allowance for doubtful accounts based upon factors surrounding the credit risk of specific customers, historical trends and other information. As of December 31, 2014, the Company had uncollateralized receivables with six customers in the automotive industry, each with several locations, aggregating $37.7 million, which represented approximately 18% of the Company’s trade accounts receivable. During 2014, sales to these customers amounted to approximately $252.6 million, which represented approximately 18% of the Company’s net sales.
Environmental	Environmental:    The Company accrues environmental costs related to existing conditions resulting from past or current operations and from which no current or future benefit is discernible. Costs that extend the life of the related property or mitigate or prevent future environmental contamination are capitalized. The Company records a liability when environmental assessments and/or remedial efforts are probable and can be reasonably estimated. The estimated liability of the Company is not reduced for possible recoveries from insurance carriers.
Legal Contingencies	Legal Contingencies:     We are involved in a variety of claims, suits, investigations and administrative proceedings with respect to commercial, premises liability, product liability, employment and environmental matters arising from the ordinary course of business. We accrue reserves for legal contingencies, on an undiscounted basis, when it is probable that we have incurred a liability and we can reasonably estimate an amount. When a single amount cannot be reasonably estimated, but the cost can be estimated within a range, we accrue the minimum amount in the range. Based upon facts and information currently available, we believe the amounts reserved are adequate for such pending matters. We monitor the development of legal proceedings on a regular basis and will adjust our reserves when, and to the extent, additional information becomes available.
Foreign Currency Translation	Foreign Currency Translation:    The functional currency for a majority of subsidiaries outside the United States is the local currency. Financial statements for these subsidiaries are translated into U.S. dollars at year-end exchange rates for assets and liabilities and weighted-average exchange rates for revenues and expenses. The resulting translation adjustments are recorded in accumulated comprehensive income (loss) in shareholders’ equity.
Earnings Per Share	Earnings from continuing operations per common share is computed as net income from continuing operations less net income attributable to noncontrolling interests divided by the weighted average basic shares outstanding. Diluted earnings from continuing operations per common share is computed as net income from continuing operations less net income attributable to noncontrolling interests divided by the weighted average diluted shares outstanding.
	Earnings (loss) from discontinued operations per common share is computed as income (loss) from discontinued operations, net of taxes divided by the weighted average basic shares outstanding. Diluted earnings (loss) from discontinued operations per common share is computed as income (loss) from discontinued operations, net of taxes divided by the weighted average diluted shares outstanding.
	Total basic earnings per common share is computed as net income attributable to Park-Ohio common shareholders divided by the weighted average basic shares outstanding. Total diluted earnings per common share is computed as net income attributable to Park-Ohio common shareholders divided by the weighted average diluted shares outstanding.
	Outstanding stock options with exercise prices greater than the average price of the common shares are anti-dilutive and are not included in the computation of diluted earnings per share. For the year ended December 31, 2014 and 2013, the anti-dilutive shares were insignificant.
Recent Accounting Pronouncements Not Yet Adopted	Recent Accounting Pronouncements Not Yet Adopted
	In April 2014, the FASB issued ASU 2014-08, “Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity,” which raises the threshold for disposals to qualify as discontinued operations and requires new disclosures for discontinued operations and for individually material disposal transactions that do not meet the definition of a discontinued operation. The ASU is effective prospectively for reporting periods beginning with the first quarter of 2015. Early adoption is permitted for disposals that have not been previously reported in the financial statements. We believe the adoption of this ASU will have an insignificant effect on our consolidated financial statement as it only applies to future disposals.
	In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers (Topic 606),” which was the result of a joint project by the FASB and International Accounting Standards Board to clarify the principles for recognizing revenue and to develop a common revenue standard for U.S. generally accepted accounting principles and International Financial Reporting Standards. The issuance of a comprehensive and converged standard on revenue recognition is expected to enable financial statement users to better understand and consistently analyze an entity’s revenue across industries, transactions, and geographies. The ASU will require additional disclosures to help financial statement users better understand the nature, amount, timing, and potential uncertainty of the revenue that is recognized. The ASU is effective for annual reporting periods beginning after December 15, 2016, and will require either retrospective application to each prior reporting period presented or retrospective application with the cumulative effect of initially applying the standard recognized at the date of adoption.

Summary of Components of Net Periodic Benefit Cost	In determining its expected return on plan assets assumption for the year ended December 31, 2014, the Company considered historical experience, its asset allocation, expected future long-term rates of return for each major asset class, and an assumed long-term inflation rate. Based on these factors, the Company derived an expected return on plan assets for the year ended December 31, 2014 of 8.25%. This assumption was supported by the asset return generation model, which projected future asset returns using simulation and asset class correlation.
