What Mayfair Plastics does

Mayfair Plastics is an engineering-led precision injection molding company serving automotive OEMs, Tier 1 suppliers, and off-highway vehicle manufacturers. Founded in 1952 in the Detroit area and relocated to Gaylord, Michigan in 1967, the company designs, engineers, and manufactures tight-tolerance plastic components for functional, performance-critical systems exposed to heat, load, vibration, and continuous operation. Core capabilities include insert molding, metal-to-plastic conversion, and secondary operations such as wire harness assembly, sonic welding, sealing, and component assembly.

The company's technology stack centers on injection molding with integrated engineering support and deep expertise in high-temperature engineered resins, including crystalline polymers (Nylon 6, 66, 9T, 46, PPS, POM, PBT, PPA, PEEK) and amorphous polymers (Polycarbonate, PEI) suited for under-hood automotive applications. Manufacturing operations run from a single 85,000+ square foot facility in Gaylord equipped with 77 molding machines and supported by approximately 130 employees.

Mayfair's business model is project-based B2B contract manufacturing with custom, non-public pricing tied to component complexity, materials, and volume. The company was acquired by Husco, a privately-owned Waukesha, Wisconsin-based supplier of hydraulic and electro-mechanical control systems, in March 2026. Mayfair retained its name, workforce, and Gaylord operations, with full integration into Husco expected by the end of fiscal 2026. The acquisition provides USMCA-compliant, US-based plastics manufacturing capabilities directly to Husco's automotive and off-highway customers.
