About Ironwood Plastics Inc.
Ironwood Plastics Inc. was founded in 1979 by Gordon K. Stephens in Ironwood, Michigan. The company was acquired by CTB, Inc., a Berkshire Hathaway subsidiary, in 2010 and operates today as a division of that organization. A second production site was established in Two Rivers, Wisconsin, giving the company a dual-facility footprint in the Upper Midwest. The company specializes in custom injection molding with a focus on complex, high-precision processes. Its core capabilities include two-shot molding, reel-to-reel molding, insert molding, close-tolerance molding, and overmolding. A scientific, data-driven approach to process development and optimization underpins production, and secondary services such as pad printing, sonic welding, and tape-and-reel packaging provide a single-source solution. The management team brings more than 200 years of combined plastics-industry experience. Primary markets served are automotive, electronics, and medical. Automotive projects have included HVAC damper components, fuel-pressure sensors, cylinder-deactivation valves, and inlet check valves for plastic fuel tanks. Electronics work centers on reel-to-reel insert-molded connectors and sensor components requiring zero-defect quality. Medical applications are referenced in the context of tight-tolerance molding for critical devices. Ironwood's stated vision since inception has been "to be a world class injection molder of complex projects." The company differentiates itself through its engineering-driven methodology, investment in in-line inspection and vision-assisted automation, and a partnership model that emphasizes traceability from resin receipt through finished product.
