Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	The accompanying unaudited consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q and include all of the information and disclosures required by accounting principles generally accepted in the United States of America for interim reporting, which are less than those required for annual reporting. In the opinion of management, the accompanying unaudited consolidated financial statements contain all adjustments (all of which are normal and recurring in nature) necessary to present fairly the financial position of Core Molding Technologies, Inc. and its subsidiaries (“Core Molding Technologies” or the “Company”) at March 31, 2020 , and the results of operations and cash flows for the three months ended March 31, 2020 . The Company has reclassified certain prior-year amounts to conform to the current-year's presentation. The “Notes to Consolidated Financial Statements” contained in the Company's Annual Report on Form 10-K for the year ended December 31, 2019, should be read in conjunction with these consolidated financial statements. Core Molding Technologies and its subsidiaries operate in the composites market as one operating segment as a molder of thermoplastic and thermoset structural products. The Company's operating segment consists of two component reporting units, Core Traditional and Horizon Plastics. The Company produces and sells molded products for varied markets, including medium and heavy-duty trucks, automobiles, marine, construction and other commercial markets. The Company offers customers a wide range of manufacturing processes to fit various program volume and investment requirements. These processes include compression molding of sheet molding compound ("SMC"), bulk molding compounds ("BMC"), resin transfer molding ("RTM"), liquid molding of dicyclopentadiene ("DCPD"), spray-up and hand-lay-up, glass mat thermoplastics ("GMT"), direct long-fiber thermoplastics ("D-LFT") and structural foam and structural web injection molding ("SIM"). As of March 31, 2020 , Core Molding Technologies has its headquarters in Columbus, Ohio, and operates seven production facilities in Columbus and Batavia, Ohio; Gaffney, South Carolina; Winona, Minnesota; Matamoros and Escobedo, Mexico; and Cobourg, Ontario, Canada. All produce structural composite products.

Critical Accounting Policy (Not

Critical Accounting Policy (Notes)	3 Months Ended
	Mar. 31, 2020
Accounting Policies [Abstract]
Significant Accounting Policies [Text Block]	On an on-going basis, management evaluates its estimates and judgments. Management bases its estimates and judgments on historical experience and on various other factors that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates, due to the uncertainty around the magnitude and duration of the COVID-19 pandemic, as well as other factors. Management believes the following critical accounting policies, among others, affect its more significant judgments and estimates used in the preparation of its consolidated financial statements. Going Concern: Under FASB ASU 2014-15, “Presentation of Financial Statements - Going Concern,” management is required to evaluate conditions or events as related to uncertainties that raise substantial doubt about the Company’s ability to continue as a going concern and to provide related financial disclosures, as applicable. Our consolidated financial statements have been prepared on a going-concern basis, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. As further discussed in Note 11, "Debt", as of March 31, 2020, the Company was not in compliance with the leverage and fixed charge coverage ratio requirements under the Company's Amended and Restated Credit Agreement, dated January 16, 2018 (the “A/R Credit Agreement”), with KeyBank National Association as the administrative agent (the "Administrative Agent") and various other financial institutions thereto as lenders (the "Lenders"). On November 22, 2019, the Company entered into a forbearance agreement (the "Forbearance Agreement") with the Lenders. Pursuant to the Forbearance Agreement, the Borrowers and the Lenders acknowledged and confirmed that an event of default occurred under the A/R Credit Agreement resulting from the Borrowers failure to maintain the required fixed charge coverage ratio (as defined in the A/R Credit Agreement) for the fiscal quarter ended September 30, 2019. The Forbearance Agreement provides that the Administrative Agent and Lenders shall forbear from the exercise of rights and remedies pursuant to the loan documents described in the A/R Credit Agreement through March 13, 2020, as long as the Company satisfies the conditions set forth in the Forbearance Agreement. See additional detail in Note 11, "Debt". On March 13, 2020, the Company entered into the first Amendment to the Forbearance Agreement (the “Amended Forbearance Agreement”) with the Lenders. The Amended Forbearance Agreement provides that the Administrative Agent and Lenders shall forbear from the exercise of rights and remedies pursuant to the loan documents described in the A/R Credit Agreement through May 29, 2020, as long as the Company satisfies the conditions set forth in the Amended Forbearance Agreement. See additional detail in Note 11, "Debt". As a result of non-compliance with the Amended Forbearance Agreement and A/R Credit Agreement, the Company’s remaining borrowings under the A/R Credit Agreement, consisting of $44,901,000 in borrowings under the revolving credit commitment and the loan commitments, were classified as a current liability in the Company’s consolidated balance sheet as of March 31, 2020. As a result, the Company’s current liabilities exceeded its current assets by $13,350,000 as of March 31, 2020. If the Lenders were to call the loans or demand repayment of all existing borrowings, this could result in the Company being unable to meet its working capital obligations. While the Company has executed an Amended Forbearance Agreement with existing Lenders, it has not met all the conditions of the Amended Forbearance Agreement. The Company cannot predict if the Lenders will exercise their rights and remedies under the A/R Credit Agreement beyond the term of the Amended Forbearance Agreement. Additionally, since the Company has no firm commitments for additional financing, there can be no assurances that the Company will be able to secure additional financing. As there can be no assurance that the Company will be able to successfully implement its refinancing plan, these conditions raise substantial doubt about the Company’s ability to continue as a going concern within one year after the date the financial statements are issued. The Company's consolidated financial statements do not include adjustments, if any, that might arise from the outcome of this uncertainty. Management has been executing on its turnaround plan that started in December of 2018 and has been successful in improving equipment uptime, improving employee retention and reducing premium freight costs for expediting shipments to customers. The Company’s financial results in the quarter ending March 31, 2020 reflect the operational improvements implemented in 2019 as the Company returned to operational profitability. Management believes that the operational turnaround is complete and is now focused on continuous improvement and operational excellence. Management has, or is in the process of taking, the following continuous improvement actions which will further improve financial performance at its operating facilities: • Implemented quality management systems that provide for continual improvement, defect prevention and reduction of variation and waste in manufacturing processes • Improved inventory management systems to reduce stock outage events which cause downtime and labor inefficiency • Implementation of improved mold and waterjet fixture change procedures to reduce production equipment downtime. • Conducted value add/value engineer projects with customers to remove waste from the operating process and reduce cost • Implementation of focused problem solving to improve quality and reduce scrap costs • Implemented cost saving measures and actions to align controllable spending and labor workforce to reduced sales volumes in the current market as a result of the COVID-19 pandemic • Implemented technical training programs specific to the Company’s products and processes • Improved free cash flow through improved terms with customers and vendors • Utilization of Kaizen techniques, process mapping and multi-functional problem solving teams to improve operational performance and reduce waste The Company recorded a tax receivable of $6,155,000 for the three months ended March 31, 2020, due to tax law changes made by the Coronavirus Aid Relief and Economic Security Act (the "CARES Act") which will allow the Company to carryback tax net operating losses, see Note 12, "Income Taxes". The funds from the utilization of the net operating losses will provide additional financial resources for the Company to operate the business and refinance its existing debt. The Company’s current and potential new lenders have been provided with the Company’s most recent improved results. Based on the updated results, the Company received multiple refinancing term sheets, but the refinancing process has been delayed due to the current capital market being affected by COVID-19. As a result of COVID-19 restrictions, several of the Company’s major customers suspended operations during April due to reduced demand and the impact of government regulations and mandates. The Company has begun to increase production starting May 4, 2020 and expects to increase production throughout the month of May as customers come back online and supply chains stabilize. Potential new lenders require Company’s customers to resume operations before proceeding with refinancing. The Company is currently negotiating a forbearance amendment with its current lenders to extend the Company’s current amended forbearance agreement. Revenue Recognition: The Company recognizes revenue from two streams, product revenue and tooling revenue. Product revenue is earned from the manufacture and sale of sheet molding compound and thermoset and thermoplastic products. Revenue from product sales is generally recognized as products are shipped, as the Company transfers control to the customer and is entitled to payment upon shipment. In certain circumstances, the Company recognizes revenue from product sales when products are produced and the customer takes control at our production facility. Tooling revenue is earned from manufacturing multiple tools, molds and assembly equipment as part of a tooling program for a customer. Given that the Company is providing a significant service of producing highly interdependent component parts of the tooling program, each tooling program consists of a single performance obligation to provide the customer the capability to produce a single product. Based on the arrangement with the customer, the Company recognizes revenue either at a point in time or over time. When the Company does not have an enforceable right to payment, the Company recognizes tooling revenue at a point in time. In such cases, the Company recognizes revenue upon customer acceptance, which is when the customer has legal title to the tools. Certain tooling programs include an enforceable right to payment. In those cases, the Company recognizes revenue over time based on the extent of progress towards completion of its performance obligation. The Company uses a cost-to-cost measure of progress for such contracts because it best depicts the transfer of value to the customer and also correlates with the amount of consideration to which the entity expects to be entitled in exchange for transferring the promised goods or services to the customer. Under the cost-to-cost measure of progress, progress towards completion is measured based on the ratio of costs incurred to date to the total estimated costs at completion of the performance obligation. Revenues are recorded proportionally as costs are incurred. Accounts Receivable Allowances: Management maintains allowances for doubtful accounts for estimated losses resulting from the inability of its customers to make required payments. If the financial condition of the Company’s customers were to deteriorate, resulting in an impairment of their ability to make payments, additional allowances may be required. The Company recorded an allowance for doubtful accounts of $ 105,000 and $50,000 at March 31, 2020 and December 31, 2019 , respectively. Management also records an allowance for estimated customer chargebacks for returns, price discounts and adjustments, premium freight and expediting costs and customer production line disruption costs resulting from late deliveries. At times, customers have asserted a right to significant production line disruption charges to recover damages as a result of late delivery. The Company typically works with its customers to minimize disruption charges, validate damages and negotiate resolution. The Company records accruals for customer chargebacks when a valid charge is probable and the amount of the charge can be reasonably estimated. Should customer chargebacks fluctuate from the estimated amounts, additional allowances may be necessary. The Company reduced accounts receivable for chargebacks by $ 368,000 at March 31, 2020 and $ 476,000 at December 31, 2019 . Inventories: Inventories, which include material, labor and manufacturing overhead, are valued at the lower of cost or net realizable value. The inventories are accounted for using the first-in, first-out (FIFO) method of determining inventory costs. Inventory quantities on-hand are regularly reviewed, and where necessary, provisions for excess and obsolete inventory are recorded based on historical and anticipated usage. The Company has recorded an allowance for slow moving and obsolete inventory of $ 915,000 at March 31, 2020 and $ 898,000 at December 31, 2019 . Contract Assets/Liabilities: Contract assets and liabilities represent the net cumulative customer billings, vendor payments and revenue recognized for tooling programs. For tooling programs where net revenue recognized and vendor payments exceed customer billings, the Company recognizes a contract asset. For tooling programs where net customer billings exceed revenue recognized and vendor payments, the Company recognizes a contract liability. Customer payment terms vary by contract and can range from progress payments based on work performed or one single payment once the contract is completed. The Company has recorded contract assets of $ 565,000 as of March 31, 2020 and $ 888,000 at December 31, 2019. Contract assets are generally classified as current within prepaid expenses and other current assets on the Consolidated Balance Sheets. During the three months ended March 31, 2020 , the Company recognized no impairments on contract assets. Contract liabilities are also generally classified as current within other current liabilities on the Consolidated Balance Sheets. For the three months ended March 31, 2020 , the Company recognized $554,000 amount of revenue from contract liabilities outstanding as of December 31, 2019. Income Taxes: The Company’s Consolidated Balance Sheets include a net non-current deferred tax asset of $2,026,000 for the Canadian and Mexican tax jurisdictions and a net non-current deferred tax liability of $517,000 for the U.S. tax jurisdiction at March 31, 2020 . The Company evaluates the balance of deferred tax assets that will be realized based on the premise that the Company is more likely than not to realize deferred tax benefits through the generation of future taxable income. For more information, refer to Note 12, "Income Taxes", of the Notes to Consolidated Financial Statements contained in the Company's Annual Report on Form 10-K for the year ended December 31, 2019 . Derivative Instruments: Derivative instruments are utilized to manage exposure to fluctuations in foreign currency exchange rates and interest rates on long term debt obligations. All derivative instruments are formally documented as cash flow hedges and are recorded at fair value at each reporting period. Gains and losses related to currency forward contracts and interest rate swaps are deferred and recorded as a component of Accumulated Other Comprehensive Income in the Consolidated Statement of Stockholders' Equity and then subsequently recognized in the Consolidated Statement of Income when the hedged item affects net income. The ineffective portion of the change in fair value of a hedge, if any, is recognized in income. For additional information on derivative instruments, see Note 14, "Fair Value of Financial Instruments". Long-Lived Assets: Long-lived assets consist primarily of property, plant and equipment and definite-lived intangibles. The recoverability of long-lived assets is evaluated by an analysis of operating results and consideration of other significant events or changes in the business environment. The Company evaluates whether impairment exists for property, plant and equipment on the basis of undiscounted expected future cash flows from operations before interest. There was no impairment of the Company's long-lived assets for the three months ended March 31, 2020 or March 31, 2019 . Goodwill and Other Intangibles: The Company evaluates goodwill annually on December 31 to determine whether impairment exists, or at interim periods if an indicator of possible impairment exists. As a result of the Horizon Plastics acquisition on January 16, 2018 and the status of its integration, the Company established two reporting units, Core Traditional and Horizon Plastics. The annual impairment tests of goodwill may be completed through qualitative assessments, however the Company may elect to bypass the qualitative assessment and proceed directly to a quantitative impairment test for any reporting unit in any period. The Company may resume the qualitative assessment for any reporting unit in any subsequent period. Due to the Company's financial performance and continued depressed stock price, the Company performed a quantitative analysis for both of its reporting units at September 30, 2019. During 2019, the Company incurred a loss of margin in its Horizon Plastics reporting unit caused by selling price decreases that the Company has not been able to fully offset with material cost reductions. As a result of the quantitative analysis, the Company concluded that the carrying value of Horizon Plastics was greater than the fair value, which resulted in a goodwill impairment charge of $ 4,100,000 at September 30, 2019 representing 19% of the goodwill related to the Horizon Plastics reporting unit. There were no indicators of impairment for the three months ended March 31, 2020 that would trigger additional analysis; however, should the Company experience a prolonged suspension of operations due to COVID-19, the Company may incur goodwill and intangible impairment charges in the future. Self-Insurance: The Company is self-insured with respect to its Columbus and Batavia, Ohio; Gaffney, South Carolina; Winona, Minnesota and Brownsville, Texas for medical, dental and vision claims and Columbus and Batavia, Ohio for workers’ compensation claims, all of which are subject to stop-loss insurance thresholds. The Company is also self-insured for dental and vision with respect to its Cobourg, Canada location. The Company has recorded an estimated liability for self-insured medical, dental, vision and worker’s compensation claims incurred but not reported at March 31, 2020 and December 31, 2019 of $ 961,000 and $ 1,203,000 , respectively. Post-retirement benefits: Management records an accrual for post-retirement costs associated with the health care plan sponsored by the Company for certain employees. Should actual results differ from the assumptions used to determine the reserves, additional provisions may be required. In particular, increases in future healthcare costs above the assumptions could have an adverse effect on the Company's operations. The effect of a change in healthcare costs is described in Note 13, "Post Retirement Benefits", of the Notes to Consolidated Financial Statements contained in the Company's Annual Report on Form 10-K for the year ended December 31, 2019. The Company had a liability for post retirement healthcare benefits based on actuarially computed estimates of $ 9,146,000 at March 31, 2020 and $ 9,160,000 at December 31, 2019 .

Accounting Changes and Error Corrections [Abstract]
Accounting Standards Update and Change in Accounting Principle [Text Block]	. RECENT ACCOUNTING PRONOUNCEMENTS Current expected credit loss (CECL) In June 2016, the FASB issued ASU 2016-13, “Financial Instruments-Credit Losses,” which changes the impairment model for most financial assets and certain other instruments. For trade and other receivables, held-to-maturity debt securities, loans and other instruments, entities will be required to use a new forward-looking “expected loss” model that will replace today’s “incurred loss” model and generally will result in the earlier recognition of allowances for losses. For available-for-sale debt securities with unrealized losses, entities will measure credit losses in a manner similar to current practice, except that the losses will be recognized as an allowance. Subsequent to issuing ASU 2016-13, the FASB issued ASU 2018-19, “Codification Improvements to Topic 326, Financial Instruments - Credit Losses,” for the purpose of clarifying certain aspects of ASU 2016-13. ASU 2018-19 has the same effective date and transition requirements as ASU 2016-13. In April 2019, the FASB issued ASU 2019-04, “Codification Improvements to Topic 326, Financial Instruments - Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments,” which is effective with the adoption of ASU 2016-13. In May 2019, the FASB issued ASU 2019-05, “Financial Instruments - Credit Losses (Topic 326),” which is also effective with the adoption of ASU 2016-13. In November 2019, the FASB voted to delay the implementation date for certain companies, including those that qualify as a smaller reporting company under SEC rules, until fiscal years beginning after December 15, 2022. We will adopt this ASU on its effective date of January 1, 2023. We do not expect the adoption of this ASU to have a material impact on our consolidated financial position, results of operations, cash flows, or presentation thereof. Facilitation of the Effects of Reference Rate Reform In March 2020, the FASB issued ASU No. 2020-04, Facilitation of the Effects of Reference Rate Reform on Financial Reporting (Topic 848). The ASU provides optional expedients and exceptions for applying GAAP to transactions affected by reference rate (e.g., LIBOR) reform if certain criteria are met, for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. The ASU is effective as of March 12, 2020 through December 31, 2022. We will evaluate transactions or contract modifications occurring as a result of reference rate reform and determine whether to apply the optional guidance on an ongoing basis.

Leases [Abstract]
Lessee, Operating Leases [Text Block]	7. LEASES The Company has operating leases with fixed payment terms for certain buildings and warehouses. The Company's leases have remaining lease terms of less than one year to five years, some of which include options to extend the lease for five years. Operating leases are included in operating lease right-of-use ("ROU") assets, and operating lease liabilities in the Consolidated Balance Sheets. ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. The Company used the applicable incremental borrowing rate at implementation date to measure lease liabilities and ROU assets. The incremental borrowing rate used by the Company was based on baseline rates and adjusted by the credit spreads commensurate with the Company’s secured borrowing rate. At each reporting period when there is a new lease initiated, the Company will utilize its incremental borrowing rate to perform lease classification tests on lease components and to measure ROU assets and lease liabilities. The components of lease expense were as follows: Three Months Ended March 31, 2020 2019 Operating lease cost $ 357,000 $ 429,000 Total net lease cost $ 357,000 $ 429,000 Other supplemental balance sheet information related to leases was as follows: Three Months Ended March 31, December 31, 2020 2019 Operating Leases: Operating lease right of use assets 4,159,000 4,484,000 Total operating lease right of use assets $ 4,159,000 $ 4,484,000 Current operating lease liabilities (A) $ 987,000 $ 1,304,000 Noncurrent operating lease liabilities 3,109,000 3,119,000 Total operating lease liabilities $ 4,096,000 $ 4,423,000 Weighted average remaining lease term (in years): Operating leases 4.0 4.0 Weighted average discount rate: Operating leases 4.9 % 4.9 % (A) Current operating lease liabilities are included in accrued other liabilities on the Consolidated Balance Sheets.

On March 14, 2019, the Company entered into the first amendment (“First Amendment”) to the A/R Credit Agreement (as amended by the First Amendment, the "Amended Credit Agreement") with the Lenders. Pursuant to the terms of the First Amendment, the Company and Lenders agreed to modify certain terms of the A/R Credit Agreement.

On November 22, 2019, the Company entered into a forbearance agreement (the "Forbearance Agreement") with the Lenders. Pursuant to the Forbearance Agreement, the Borrowers and the Lenders acknowledged and confirmed that an event of default occurred under the A/R Credit Agreement resulting from the Borrowers failure to maintain the required Fixed Charge Coverage Ratio (as defined in the A/R Credit Agreement) for the fiscal quarter ended September 30, 2019. The Forbearance Agreement provides that the Administrative Agent and Lenders shall forbear from the exercise of rights and remedies pursuant to the Loan Documents described in the A/R Credit Agreement through March 13, 2020, as long as the Company satisfies the conditions set forth in the Forbearance Agreement, including, (i) the Borrowers shall remain current on all loan payments during the forbearance period, (ii) on or before December 6, 2019, the Administrative Agent and Lenders shall each receive a copy of a report of Huron Consulting Group containing findings and observations in respect of the businesses and operations of the Company and the Borrowers shall deliver a strategic alternative assessment in respect of the Borrowers’ operations and financing, (iii) on or before December 15, 2019, the Administrative Agent and Lenders shall each receive a copy of appraisals of machinery and equipment and inventory appraisals, and the Borrowers shall have determined and proposed a new capital structure to the Administrative Agent and Lenders, (iv) on or before February 14, 2020, the Borrowers shall have obtained a definitive, written commitment from involved parties and/or lenders providing the basis for implementation of a new capital structure, and (v) on or before March 13, 2020, the Borrowers shall have closed on a new capital structure, acceptable to the Administrative Agents and Lenders. The Forbearance Agreement also implemented a new availability block with respect to the U.S. Revolving Loans portion of the A/R Credit Agreement, reducing availability from $32,500,000 to $28,000,000 and increasing the applicable margin for existing term and revolving loans, as well as increasing the commitment fees on any unused U.S. Revolving Loans. On March 13, 2020, the Company entered into the first Amendment to the Forbearance Agreement (the “Amended Forbearance Agreement”) with the Lenders. Pursuant to the terms of the Amended Forbearance Agreement, the Company and Lenders agreed to modify certain terms of the Forbearance Agreement and extend the Forbearance Agreement through May 29, 2020. The modifications include (1) a reduction in the U.S. Revolving Loan to $25,000,000 with an availability block of $5,000,000 which can be borrowed with the approval of the lenders, (2) a change of interest rate to LIBOR rate plus 650 basis points, (3) forebear compliance with the leverage covenant and fixed charge covenant through May 29, 2020, and (4) implementation of a capital expenditure spend limit of $3,500,000 from the effective date of the Amended Forbearance Agreement through May 29, 2020. The Amended Forbearance Agreement provides that the Administrative Agent and Lenders shall forbear from the exercise of rights and remedies pursuant to the Loan Documents described in the Credit Agreement through May 29, 2020, as long as the Company satisfies the conditions set forth in the Amended Forbearance Agreement, including, (i) on or before March 31, 2020, the borrowers shall have obtained an executed term sheet from involved parties and/or lenders providing the basis for implementation of a new capital structure and defined due diligence parameters, (ii) on or before May 15, 2020 the Borrowers shall have obtained an executed definitive, written commitment from the new lenders to enter into a definitive agreement to effect the refinancing, and (iii) on or before May 29, 2020, the borrowers shall have closed on a new capital structure. Due to the COVID-19 pandemic, several of the Company’s customers have suspended operations due to reduced demand and government regulations and mandates. As a result of customer demand reductions, the Company temporarily ceased operations at several of its manufacturing facilities. Because of the temporary shutdown of the Company's facilities and the economic uncertainty due to the pandemic, the Company’s ability to complete a refinancing has been delayed. Potential lenders are requiring the reestablishment of normal operations in order to proceed with a refinancing. The Company and its current lenders are negotiating an extension of the forbearance agreement that will allow the Company to continue with its refinancing efforts once operations resume. As a result of non-compliance with the Amended Forbearance Agreement and A/R Credit Agreement, the Company’s remaining borrowings under the A/R Credit Agreement, consisting of $44,901,000 under the revolving credit commitment and the term loan commitments, were classified as a current liability in the Company’s consolidated balance sheet as of March 31, 2020. As a result, the Company’s current liabilities exceeded its current assets by $13,350,000 as of March 31, 2020. If the Lenders were to call the loans or demand repayment of all existing borrowings, this could result in the Company being unable to meet its working capital obligations. The Company has unblocked maximum availability of $20,000,000 of variable rate revolving loans of which $7,776,000 is outstanding as of March 31, 2020 . Bank Covenants The Company is required to meet certain financial covenants included in the A/R Credit Agreement with respect to leverage ratios, fixed charge ratios and capital expenditures. As of March 31, 2020, the Company was in default with its fixed charge coverage and leverage ratio covenants associated with the loans made under the A/R Credit Agreement as described above. As a result of this default the Company and the Administrative Agent on behalf of the Lenders entered into an Amended Forbearance Agreement to address the non-compliance and establish milestones for the Company related to restructuring of its existing debt. Management is pursuing the restructuring or refinancing of its existing obligations under the A/R Credit Agreement. The Company has engaged Huron Transactional Advisor's to facilitate a full marketing processes for refinancing the A/R Credit Agreement. Management and Huron are evaluating term sheets submitted by potential lending sources. The Company is considering financing options including an asset backed lending facility using the Company’s accounts receivable and inventories as security, term loans secured with the Company’s real estate and machinery and equipment, sale and leaseback of Company owned real estate and potential equity financing. Any new financing remains subject to asset appraisals, field exams, financial projection due diligence, real estate environmental reviews, and other customary legal documentation. Interest Rate Swaps The Company entered into two interest rate swap agreements that became effective January 18, 2018 and continue through January 2023, one of which was designated as a cash flow hedge for $ 25,000,000 of the $ 32,000,000 term loan to the Company mentioned above and the other designated as a cash flow hedge for $ 10,000,000 of the $ 13,000,000 term loan to the Subsidiary mentioned above. Under these agreements, the Company will pay a fixed rate of approximately 2.49% to the counterparty and receives 30 day LIBOR for both cash flow hedges. The fair value of the interest rate swap was a liability of $1,489,000 and $706,000 at March 31, 2020 and December 31, 2019 , respectively. While the Company is exposed to credit loss on its interest rate swaps in the event of non-performance by the counterparty to the swap, management believes that such non-performance is unlikely to occur given the financial resources of the counterparty.

Income Tax Disclosure [Abstract]
Income Taxes	The Company evaluates the balance of deferred tax assets that will be realized based on the premise that the Company is more likely than not to realize deferred tax benefits through the generation of future taxable income. As of March 31, 2020 and December 31, 2019 , the Company had no liability for unrecognized tax benefits. The Company does not anticipate that unrecognized tax benefits will significantly change within the next twelve months. Income tax benefit for the three months ended March 31, 2020 is estimated to be $ 4,854,000 , approximately 156% of the income before income taxes. Income tax benefit for the three months ended March 31, 2019 was estimated to be $ 1,044,000 , or approximately 21% of income before income taxes. On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (the "CARES Act") was enacted in response to the COVID-19 pandemic, and among other things, provides tax relief to businesses. Tax provisions of the CARES Act include the deferral of certain payroll taxes, relief for retaining employees, and other provisions, including allowing net operating losses to be carried back five years versus an indefinite carryforward. The Company plans to carry back net operating losses incurred in 2018 and 2019 under this new law, resulting in an income tax receivable of $6,155,000 that is expected to be received this fiscal year, as well as an income tax benefit of $ 5,638,000 that is realized this quarter. The income tax benefit consists of the reversal of the full valuation allowance against net deferred tax assets in the United States for approximately $ 3,267,000 . It also consists of a rate benefit of $ 2,371,000 based on the losses being carried back to years where the Company paid tax at 34% compared to the valuation of the losses being recorded at the 21% current U.S. statutory tax rate. The Company files income tax returns in the U.S., Mexico, Canada and various state jurisdictions. The Company is not subject to U.S. federal and state income tax examinations by tax authorities for years prior to 2016, not subject to Mexican income tax examinations by Mexican authorities for years prior to 2014 and not subject to Canadian tax examinations by Canadian authorities for years prior to 2018.

Stock Based Compensation

Share-based Payment Arrangement, Noncash Expense [Abstract]
Stock Based Compensation	The Company has a Long Term Equity Incentive Plan (the “2006 Plan”), as approved by the Company’s stockholders in May 2006 and as amended in May 2015. The 2006 Plan allows for grants to directors and employees of non-qualified stock options, incentive stock options, stock appreciation rights, restricted stock, performance shares, performance units and other incentive awards (“Stock Awards”) up to an aggregate of 3,000,000 awards, each representing a right to buy a share of Core Molding Technologies common stock. Stock Awards can be granted under the 2006 Plan through the earlier of December 31, 2025, or the date the maximum number of available awards under the 2006 Plan have been granted. Restricted Stock The Company grants shares of its common stock to certain directors, officers, key managers and employees in the form of unvested stock and units (“Restricted Stock”). These awards are recorded at the market value of the Company's common stock on the date of issuance and amortized ratably as compensation expense over the applicable vesting period, which is typically three years. The Company adjusts compensation expense for actual forfeitures, as they occur. The following summarizes the status of Restricted Stock and changes during the three months ended March 31, 2020 : Number of Shares Weighted Average Grant Date Fair Value Unvested balance at December 31, 2019 343,919 $ 9.37 Granted — — Vested (4,771 ) 17.92 Forfeited (8,385 ) 13.72 Unvested balance at March 31, 2020 330,763 $ 9.14 At March 31, 2020 and 2019 , there was $ 1,292,000 and $ 2,349,000 , respectively, of total unrecognized compensation expense, related to Restricted Stock granted under the 2006 Plan. That cost is expected to be recognized over the weighted-average period of 2.3 years. Total compensation cost related to restricted stock grants for the three months ended March 31, 2020 and 2019 was $ 292,000 and $ 350,000 , respectively, all of which was recorded to selling, general and administrative expense. During the three months ended March 31, 2020 and 2019 , employees surrendered no shares of the Company's common stock to satisfy income tax withholding obligations in connection with the vesting of restricted awards. Stock Appreciation Rights As part of the Company's 2019 annual grant, Stock Appreciation Rights (SARs) were granted with a grant price of $ 10 . These awards have a contractual term of five years and vest ratably over a period of three years or immediately vest if the recipient is over 65 years of age. These awards are valued using the Black-Scholes option pricing model. A summary of the Company's stock appreciation rights activity for the quarter ended March 31, 2020 is as follows: Number of Weighted Average Outstanding as of December 31, 2019 222,112 $ 2.57 Granted — — Exercised — — Forfeited (27,266 ) 2.57 Outstanding at the period ended March 31, 2020 194,846 $ 2.57 Exercisable at the period ended March 31, 2020 29,028 $ 2.57 The average remaining contractual term for those SARs outstanding at March 31, 2020 is 4.1 years, with no aggregate intrinsic value. At March 31, 2020 and 2019 , there was $ 292,000 and $ 0 , respectively, of total unrecognized compensation expense, net of estimated forfeitures, related to SARs. Total compensation cost related to SARs for the three months ended March 31, 2020 and 2019 was $24,000 and $0 , respectively, all of which was recorded to selling, general and administrative expense. That cost is expected to be recognized over the weighted-average period of 2.1 years.

Fair Value of Financial Instrum

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in a transaction between market participants as of the measurement date. Fair value is measured using the fair value hierarchy and related valuation methodologies as defined in the authoritative literature. This guidance provides a fair value framework that requires the categorization of assets and liabilities into three levels based upon the assumptions (inputs) used to price the assets or liabilities. Level 1 provides the most reliable measure of fair value, whereas Level 3 generally requires significant management judgment. The three levels are defined as follows: Level 1 - Quoted prices in active markets for identical assets and liabilities. Level 2 - Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active and model-derived valuations, in which all significant inputs are observable in active markets. Level 3 - Significant unobservable inputs reflecting management's own assumptions about the inputs used in pricing the asset or liability. The Company’s financial instruments consist of cash and cash equivalents, accounts receivable, accounts payable, debt, interest rate swaps and foreign currency derivatives. Cash and cash equivalents, accounts receivable and accounts payable carrying values as of March 31, 2020 and December 31, 2019 approximate fair value due to the short-term maturities of these financial instruments. The carrying amounts of long-term debt and the revolving line of credit approximate fair value as of March 31, 2020 and December 31, 2019 due to the short term nature of the underlying variable rate LIBOR agreements. The Company had Level 2 fair value measurements at March 31, 2020 and December 31, 2019 relating to the Company’s interest rate swaps and foreign currency derivatives. Derivative and Hedging Activities Foreign currency derivatives The Company conducted business in foreign countries and paid certain expenses in foreign currencies; therefore, the Company was exposed to foreign currency exchange risk between the U.S. Dollar and foreign currencies, which could impact the Company’s operating income and cash flows. To mitigate risk associated with foreign currency exchange, the Company entered into forward contracts to exchange a fixed amount of U.S. Dollars for a fixed amount of foreign currency, which will be used to fund future foreign currency cash flows. At inception, all forward contracts are formally documented as cash flow hedges and are measured at fair value each reporting period. Derivatives are formally assessed both at inception and at least quarterly thereafter, to ensure that derivatives used in hedging transactions are highly effective in offsetting changes in cash flows of the hedged item. If it is determined that a derivative ceases to be a highly effective hedge, or if the anticipated transaction is no longer probable of occurring, hedge accounting is discontinued, and any future mark-to-market adjustments are recognized in earnings. The effective portion of gain or loss is reported in other comprehensive income and the ineffective portion is reported in earnings. The impacts of these contracts were largely offset by gains and losses resulting from the impact of changes in exchange rates on transactions denominated in the foreign currency. As of March 31, 2020 , the Company had no ineffective portion related to the cash flow hedges. Interest Rate Swaps The Company entered into interest rate swap contracts to fix the interest rate on an initial aggregate amount of $35,000,000 thereby reducing exposure to interest rate changes. The Company pays a fixed rate of approximately 2.49% to the counterparty and receives 30 day LIBOR for both cash flow hedges. At inception, all interest rate swaps were formally documented as cash flow hedges and are measured at fair value each reporting period. See Note 11, "Debt", for additional information.

Critical Accounting Policy (Policies)	3 Months Ended

Accounting Policies [Abstract]
Contract with Customer, Asset and Liability [Policy Text Block]	Contract Assets/Liabilities: Contract assets and liabilities represent the net cumulative customer billings, vendor payments and revenue recognized for tooling programs. For tooling programs where net revenue recognized and vendor payments exceed customer billings, the Company recognizes a contract asset. For tooling programs where net customer billings exceed revenue recognized and vendor payments, the Company recognizes a contract liability. Customer payment terms vary by contract and can range from progress payments based on work performed or one single payment once the contract is completed. The Company has recorded contract assets of $ 565,000 as of March 31, 2020 and $ 888,000 at December 31, 2019. Contract assets are generally classified as current within prepaid expenses and other current assets on the Consolidated Balance Sheets. During the three months ended March 31, 2020 , the Company recognized no impairments on contract assets. Contract liabilities are also generally classified as current within other current liabilities on the Consolidated Balance Sheets. For the three months ended March 31, 2020 , the Company recognized $554,000 amount of revenue from contract liabilities outstanding as of December 31, 2019.
Postemployment Benefit Plans, Policy [Policy Text Block]	Post-retirement benefits: Management records an accrual for post-retirement costs associated with the health care plan sponsored by the Company for certain employees. Should actual results differ from the assumptions used to determine the reserves, additional provisions may be required. In particular, increases in future healthcare costs above the assumptions could have an adverse effect on the Company's operations. The effect of a change in healthcare costs is described in Note 13, "Post Retirement Benefits", of the Notes to Consolidated Financial Statements contained in the Company's Annual Report on Form 10-K for the year ended December 31, 2019. The Company had a liability for post retirement healthcare benefits based on actuarially computed estimates of $ 9,146,000 at March 31, 2020 and $ 9,160,000 at December 31, 2019 .
Self Insurance Reserve [Policy Text Block]	Self-Insurance: The Company is self-insured with respect to its Columbus and Batavia, Ohio; Gaffney, South Carolina; Winona, Minnesota and Brownsville, Texas for medical, dental and vision claims and Columbus and Batavia, Ohio for workers’ compensation claims, all of which are subject to stop-loss insurance thresholds. The Company is also self-insured for dental and vision with respect to its Cobourg, Canada location. The Company has recorded an estimated liability for self-insured medical, dental, vision and worker’s compensation claims incurred but not reported at March 31, 2020 and December 31, 2019 of $ 961,000 and $ 1,203,000 , respectively.
Goodwill and Intangible Assets, Policy [Policy Text Block]	Goodwill and Other Intangibles: The Company evaluates goodwill annually on December 31 to determine whether impairment exists, or at interim periods if an indicator of possible impairment exists. As a result of the Horizon Plastics acquisition on January 16, 2018 and the status of its integration, the Company established two reporting units, Core Traditional and Horizon Plastics. The annual impairment tests of goodwill may be completed through qualitative assessments, however the Company may elect to bypass the qualitative assessment and proceed directly to a quantitative impairment test for any reporting unit in any period. The Company may resume the qualitative assessment for any reporting unit in any subsequent period. Due to the Company's financial performance and continued depressed stock price, the Company performed a quantitative analysis for both of its reporting units at September 30, 2019. During 2019, the Company incurred a loss of margin in its Horizon Plastics reporting unit caused by selling price decreases that the Company has not been able to fully offset with material cost reductions. As a result of the quantitative analysis, the Company concluded that the carrying value of Horizon Plastics was greater than the fair value, which resulted in a goodwill impairment charge of $ 4,100,000 at September 30, 2019 representing 19% of the goodwill related to the Horizon Plastics reporting unit. There were no indicators of impairment for the three months ended March 31, 2020 that would trigger additional analysis; however, should the Company experience a prolonged suspension of operations due to COVID-19, the Company may incur goodwill and intangible impairment charges in the future.
Derivative Instruments and Hedging Activities Disclosure [Text Block]	Derivative Instruments: Derivative instruments are utilized to manage exposure to fluctuations in foreign currency exchange rates and interest rates on long term debt obligations. All derivative instruments are formally documented as cash flow hedges and are recorded at fair value at each reporting period. Gains and losses related to currency forward contracts and interest rate swaps are deferred and recorded as a component of Accumulated Other Comprehensive Income in the Consolidated Statement of Stockholders' Equity and then subsequently recognized in the Consolidated Statement of Income when the hedged item affects net income. The ineffective portion of the change in fair value of a hedge, if any, is recognized in income. For additional information on derivative instruments, see Note 14, "Fair Value of Financial Instruments".
Inventory, Policy [Policy Text Block]	Inventories: Inventories, which include material, labor and manufacturing overhead, are valued at the lower of cost or net realizable value. The inventories are accounted for using the first-in, first-out (FIFO) method of determining inventory costs. Inventory quantities on-hand are regularly reviewed, and where necessary, provisions for excess and obsolete inventory are recorded based on historical and anticipated usage. The Company has recorded an allowance for slow moving and obsolete inventory of $ 915,000 at March 31, 2020 and $ 898,000 at December 31, 2019 .
Receivables, Trade and Other Accounts Receivable, Allowance for Doubtful Accounts, Policy [Policy Text Block]	Accounts Receivable Allowances: Management maintains allowances for doubtful accounts for estimated losses resulting from the inability of its customers to make required payments. If the financial condition of the Company’s customers were to deteriorate, resulting in an impairment of their ability to make payments, additional allowances may be required. The Company recorded an allowance for doubtful accounts of $ 105,000 and $50,000 at March 31, 2020 and December 31, 2019 , respectively. Management also records an allowance for estimated customer chargebacks for returns, price discounts and adjustments, premium freight and expediting costs and customer production line disruption costs resulting from late deliveries. At times, customers have asserted a right to significant production line disruption charges to recover damages as a result of late delivery. The Company typically works with its customers to minimize disruption charges, validate damages and negotiate resolution. The Company records accruals for customer chargebacks when a valid charge is probable and the amount of the charge can be reasonably estimated. Should customer chargebacks fluctuate from the estimated amounts, additional allowances may be necessary. The Company reduced accounts receivable for chargebacks by $ 368,000 at March 31, 2020 and $ 476,000 at December 31, 2019 .
Revenue [Policy Text Block]	Revenue Recognition: The Company recognizes revenue from two streams, product revenue and tooling revenue. Product revenue is earned from the manufacture and sale of sheet molding compound and thermoset and thermoplastic products. Revenue from product sales is generally recognized as products are shipped, as the Company transfers control to the customer and is entitled to payment upon shipment. In certain circumstances, the Company recognizes revenue from product sales when products are produced and the customer takes control at our production facility. Tooling revenue is earned from manufacturing multiple tools, molds and assembly equipment as part of a tooling program for a customer. Given that the Company is providing a significant service of producing highly interdependent component parts of the tooling program, each tooling program consists of a single performance obligation to provide the customer the capability to produce a single product. Based on the arrangement with the customer, the Company recognizes revenue either at a point in time or over time. When the Company does not have an enforceable right to payment, the Company recognizes tooling revenue at a point in time. In such cases, the Company recognizes revenue upon customer acceptance, which is when the customer has legal title to the tools. Certain tooling programs include an enforceable right to payment. In those cases, the Company recognizes revenue over time based on the extent of progress towards completion of its performance obligation. The Company uses a cost-to-cost measure of progress for such contracts because it best depicts the transfer of value to the customer and also correlates with the amount of consideration to which the entity expects to be entitled in exchange for transferring the promised goods or services to the customer. Under the cost-to-cost measure of progress, progress towards completion is measured based on the ratio of costs incurred to date to the total estimated costs at completion of the performance obligation. Revenues are recorded proportionally as costs are incurred.
Income Tax, Policy [Policy Text Block]	Income Taxes: The Company’s Consolidated Balance Sheets include a net non-current deferred tax asset of $2,026,000 for the Canadian and Mexican tax jurisdictions and a net non-current deferred tax liability of $517,000 for the U.S. tax jurisdiction at March 31, 2020 . The Company evaluates the balance of deferred tax assets that will be realized based on the premise that the Company is more likely than not to realize deferred tax benefits through the generation of future taxable income. For more information, refer to Note 12, "Income Taxes", of the Notes to Consolidated Financial Statements contained in the Company's Annual Report on Form 10-K for the year ended December 31, 2019 .
Impairment or Disposal of Long-Lived Assets, Policy [Policy Text Block]	Long-Lived Assets: Long-lived assets consist primarily of property, plant and equipment and definite-lived intangibles. The recoverability of long-lived assets is evaluated by an analysis of operating results and consideration of other significant events or changes in the business environment. The Company evaluates whether impairment exists for property, plant and equipment on the basis of undiscounted expected future cash flows from operations before interest. There was no impairment of the Company's long-lived assets for the three months ended March 31, 2020 or March 31, 2019 .
