Reaction Injection Molding

Upload your CAD files (Pro-E, SolidWorks, STP or IGES) along with your annual volumes, paint requirements and other project specific information and we’ll prepare an estimate for the cost and timing for the RIM tooling and part costs of your project.

What is Reaction Injection Molding?

RIM (reaction injection molding) is a process that involves injecting two liquid raw materials (polyol and isocyanate) separately into a heated mold cavity using only a small amount of pressure. The two liquids combine to create an exothermic reaction where they polymerize to form a molded part.

This RIM process can achieve a broad range of physical properties. Depending on the formulation and mix ratios of the two raw material components of the polyurethane, the finished parts can be foamed, a solid, dual-density foam, and can vary from being flexible to very rigid.
