Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation
	The condensed consolidated financial statements include the accounts of Park-Ohio Industries, Inc. and its subsidiaries (collectively, “we”, “our” or the “Company”). All significant intercompany transactions have been eliminated in consolidation. Park-Ohio Industries, Inc. is a wholly-owned subsidiary of Park-Ohio Holdings Corp. (“Holdings”). Certain amounts in the prior years’ financial statements have been reclassified to conform to the current year presentation.
	The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the three-month period ended March 31, 2015 are not necessarily indicative of the results that may be expected for the year ending December 31, 2015. The balance sheet at December 31, 2014 has been derived from the audited financial statements at that date, but does not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. For further information, refer to the consolidated financial statements and footnotes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2014.
	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.

	Accounting Pronouncements 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. The adoption had no effect on our consolidated financial statement as it only applies to future disposals.
	Recent Accounting Pronouncements Not Yet Adopted
	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, including interim periods within that reporting period, however, in April 2015, the FASB proposed a one-year deferral of this standard with a new effective date of December 15, 2017. The ASU 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.
	In April 2015, the FASB issued ASU 2015-03, "Interest-Imputation of Interest: Simplifying the Presentation of Debt Issuance Costs." The amendment requires an entity to present debt issuance costs in the balance sheet as a direct deduction from the related debt liability rather than as an asset. Amortization of the debt issuance costs will continue to be reported as interest expense. This ASU is effective for fiscal years beginning after December 15, 2015 and interim periods within those fiscal years. Early adoption is permitted. The new guidance will be applied retrospectively to each prior period presented. The Company is currently evaluating the impact of adopting this guidance.

Segment Reporting [Abstract]
Segments	Segments
	The Company operates through three reportable segments: Supply Technologies, Assembly Components and Engineered Products. Supply Technologies provides our customers with Total Supply Management™ services for a broad range of high-volume, specialty production components. Total Supply Management™ manages the efficiencies of every aspect of supplying production parts and materials to our customers’ manufacturing floor, from strategic planning to program implementation, and includes such services as engineering and design support, part usage and cost analysis, supplier selection, quality assurance, bar coding, product packaging and tracking, just-in-time and point-of-use delivery, electronic billing services and ongoing technical support. Assembly Components manufactures cast aluminum components, automotive and industrial rubber and thermoplastic products, gasoline direct injection systems, fuel filler and hydraulic assemblies for automotive, agricultural equipment, construction equipment, heavy-duty truck and marine equipment industries. Assembly Components also provides value-added services such as design and engineering, machining and assembly. Engineered Products operates a diverse group of niche manufacturing businesses that design and manufacture a broad range of high quality products engineered for specific customer applications.
	The Company primarily evaluates performance and allocates resources based on segment operating income as well as projected future performance. Segment operating income is defined as revenues less expenses identifiable to the product lines included within each segment. Segment operating income reconciles to consolidated income before income taxes by deducting corporate costs that are not attributable to the segments and net interest expense.
	Results by business segment were as follows:

	The following table summarizes the Company's recent acquisitions:
	Description		Date of Transaction	Purchase			Acquired	Segment
				Consideration
				(In millions)
	Saet S.p.A		4-Dec-14	$	22.1		100% of equity	Engineered Products
		An Italian based leader in the design, manufacturing and testing of induction heating equipment and heat treat solutions through its locations in Italy, China, India and Tennessee.
	Autoform Tool & Manufacturing		10-Oct-14	$	48.9		100% of equity	Assembly Components
		An Indiana supplier of high end pressure fuel lines used in Gasoline Direct Injection systems across a large number of engine platforms.
	Apollo Group Limited		10-Jun-14	$	6.5	*	100% of equity	Supply Technologies
		A U.K. supply chain management services company providing Class C production components and supply chain solutions to aerospace customers worldwide.
	* Purchase consideration is net of cash acquired.
	The acquisitions of Apollo and Autoform were accounted for under the acquisition method of accounting. The purchase price allocations were preliminary as of March 31, 2015. The Apollo purchase agreement provides for 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 and at March 31, 2015, the fair value of the earn-out was approximately $1.6 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 are 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 intangible assets and deferred income tax assets and liabilities for Apollo and Autoform 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 $5.6 million was recorded.
	The acquisition of Saet was accounted for under the acquisition method of accounting. The entire purchase price allocation for Saet is preliminary. At March 31, 2015, 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, 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.

	Balance at March 31, 2015	$	7.2		$	53.9		$	25.8		$	86.9
	During the first quarter of 2015, we adjusted the preliminary goodwill recorded for Autoform primarily to reflect the adjustments to the determination of fair value of acquired intangible assets. The 2014 condensed consolidated financial statements have not been retroactively adjusted as these measurement period adjustments did not have a material impact on such statements.
	The increase in goodwill from January 1, 2014 is due to the acquisitions of Apollo, Autoform and Saet. The goodwill associated with the Apollo and Saet transactions is not deductible for income tax purposes.

	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, increased the revolving credit facility to $230.0 million, provided a term loan for $16.1 million and extended 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.
	The Amended Credit Agreement was further amended in accordance with Amendments No. 1, 2 and 3 to the Amended Credit Agreement, dated October 24, 2014, January 20, 2015 and March 12, 2015, respectively (the “Amendments”). The Amendments:
	•	increase the revolving credit facility from $230.0 million to $275.0 million;
	•	increase 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;
	•	reload the term loan up to $35.0 million from $15.5 million, of which $31.2 million has been borrowed and is outstanding as of March 31, 2015;
	•	increase the Canadian sub-limit up to $25.0 million from $15.0 million;
	•	increase the European sub-limit up to $25.0 million from $10.0 million; and
	•	provide 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 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 deposit offered rate plus 1.5% to 2.5%;
	•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. 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 following table represents fair value information of the Company's Senior Notes, classified as Level 1, at March 31, 2015 and December 31, 2014. The fair value was estimated using quoted market prices.

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. 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 $10.0 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, which the Company recognized and accrued for at that time. 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 claim 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 claim 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. IPSCO's motion to recover attorney's 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 Securities and Exchange Commission (“SEC”) in connection with the staff’s investigation of a third party. At that time, the Company also learned that the U.S. 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.
	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.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Use of 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.
New Accounting Pronouncements	Accounting Pronouncements 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. The adoption had no effect on our consolidated financial statement as it only applies to future disposals.
	Recent Accounting Pronouncements Not Yet Adopted
	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, including interim periods within that reporting period, however, in April 2015, the FASB proposed a one-year deferral of this standard with a new effective date of December 15, 2017. The ASU 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.
	In April 2015, the FASB issued ASU 2015-03, "Interest-Imputation of Interest: Simplifying the Presentation of Debt Issuance Costs." The amendment requires an entity to present debt issuance costs in the balance sheet as a direct deduction from the related debt liability rather than as an asset. Amortization of the debt issuance costs will continue to be reported as interest expense. This ASU is effective for fiscal years beginning after December 15, 2015 and interim periods within those fiscal years. Early adoption is permitted. The new guidance will be applied retrospectively to each prior period presented. The Company is currently evaluating the impact of adopting this guidance.
