The Jor-Mac Company
The Jor-Mac Company has manufactured metal fabrications for Fortune 1000 OEMs since 1952, operating captive manufacturing facilities in Wisconsin.
The Jor-Mac Company
Founded in 1952 and headquartered in Lomira, Wisconsin, The Jor-Mac Company operates as a contract manufacturer of metal fabrications, enclosures, and assemblies for original equipment manufacturers. The company serves a diversified base of Fortune 1000 and middle-market customers across the United States from its headquarters and a secondary facility in Oshkosh, Wisconsin. The firm's deployment centers on direct manufacturing operations, with a strategy that integrates metal fabrication, engineering services, custom NEMA enclosures, and powder coating under a single roof. Its recent acquisition of Muza Metal Products expanded operational capacity and engineering depth, adding a second location that the company states can be further scaled. Jor-Mac's business model targets long-cycle production partnerships with industrial OEMs, supported by in-house design-for-manufacturability prototyping, ERP-driven inventory management, and ISO 9001:2015 certified quality systems. Jor-Mac maintains a non-union workforce across its two Wisconsin facilities and describes its posture as financially strong with capital allocated for growth and investment. The company publicly emphasizes lean manufacturing disciplines and continuous improvement rather than third-party capital management or financial portfolio activity. In 2024, Jor-Mac completed the strategic acquisition of Muza Metal Products, unifying both companies under the Jor-Mac brand to broaden its sheet metal solutions and customer reach. The company's structural differentiator lies in its captive operating-company model: rather than acting as a financial allocator, Jor-Mac channels capital directly into expanding its own manufacturing footprint and production lines. Governance is concentrated within an experienced management team, and the firm publicly positions itself as a collaborative production partner rather than a holding company or diversified investment platform.

Frequently asked questions
What does The Jor-Mac Company actually produce?
The company is a contract manufacturer of metal fabrications, assemblies, custom enclosures, and NEMA-rated metal cabinets. Its services span full metal fabrication engineering, including SolidWorks design and programming, as well as powder coating on what it describes as one of the industry's most sophisticated lines. Jor-Mac primarily serves original equipment manufacturers across diversified industrial end markets.
Is Jor-Mac a family office or an operating business?
Based on available public information, The Jor-Mac Company operates as a direct manufacturing business rather than a financial family office.

Its governance appears concentrated in an experienced management team overseeing day-to-day manufacturing.
Where does Jor-Mac's underlying wealth or capital come from?
