Bruin Manufacturing

Since 1949, Bruin Manufacturing Company has been a trusted leader in American manufacturing. Family-owned and operated, our journey began in Marshalltown, Iowa, as a machine shop that evolved into die casting before finding its true calling in the late 1950s: high-precision plastic injection molding. To ensure absolute business continuity, risk mitigation, and scalable growth for our clients, we expanded our footprint in 2016 with a second state-of-the-art production facility in Newton, Iowa. What truly sets Bruin apart is our seamless, under-one-roof production ecosystem. Featuring full design, engineering, and onsite tool-room capabilities, we design, build, and maintain our clients' molds in-house. Because we control the entire lifecycle from blueprint to final part, we eliminate production delays, slash lead times, and reduce costs. Built from premium tool steel and maintained by our expert team, we proudly warrant our molds for life at no additional cost—delivering parts that consistently exceed expectations.
