Reaction Injection Molding

MRC Manufacturing offers reaction injection molding (RIM) services for the rapid production of strong, flexible, lightweight parts. The RIM process consists of high-pressure injection of liquid polyurethane thermosetting polymers into a mold, where the mixture chemically reacts to expand and cure. Greater part strength can be achieved by adding reinforcing agents, such as Mica or Wollastonite fillers, to the polyol. Compared to injection molding, RIM is an excellent alternative for large plastic parts produced in low volume quantities on several tooling options.

Our well-equipped facility houses machinery capable of injection pressures up to 30 lbs./sec into molds with multiple cavities. Class A surface finishes are easily achieved, and inserts are readily accommodated. We perform inspections in accordance with customer requirements and our quality management system is TS 16949 certified for continuous improvement. As a lean manufacturer, our work processes are efficient, which enables us to cut lead times, reduce operating costs, and ultimately save you money.

We offer complete turnkey services from concept to completion. Our knowledgeable engineering team has many years of experience in the automotive and heavy equipment industries. All parts produced by our reaction injection molding services will prove dimensionally stable, physically tough, and wear resistant. For more information on how our RIM services can improve your next project, contact us today.
