About Us
Headquartered in Marshalltown, IA since 1949

Bruin Manufacturing Company is a family-owned plastic injection molding company located in the same spot in Marshalltown, Iowa, since the day we opened in 1949. What began as a machine shop that grew into die casting then ultimately transitioned exclusively to plastic injection molding in the late 1950’s. A second production location was opened in 2016 in Newton, Iowa, for risk mitigation and growth.

At Bruin, we offer a full suite of design and engineering services, along with a full-service tool room. Since Bruin designs, builds, and maintains our client’s molds onsite then produces the parts, we can immediately solve any production issues that may arise. This enables us to deliver molds that meet our customers’ exact specifications and requirements at lower costs and turnaround times.

Since Bruin builds molds from premium tool steel and is in control of the part production process from design to final product, we warrant our molds for life at no additional cost. We set high standards to make sure your parts meet or exceed your expectations.
