The Reaction Injection Molding (RIM) process allows RIM Manufacturing ( to produce affordable, large, light weight polyurethane parts for all industries. Parts can be structural foam, flexible foam, elastomeric or solid RIM. The RIM process opens up design possibilities that injection molding, vacuum forming, pressure forming, and other technologies can impose on your parts.  Our video shows the Reaction Injection Molding process in action and, specifically, you can watch the chemical reaction to better understand the definitive advantage of the RIM process versus other processes.
