The process takes its name from a chemical reaction that occurs within the tool. The plastics used are thermosets, either polyurethanes or foamed polyurethanes. The two components that produce the polyurethane are mixed just prior toinjection into the tool. With the low viscosity and low injection pressures, large, complex parts can be produced economically in low quantities.
ReactionInjection Molding (RIM) produces parts with intricate detail that aredimensionally stable, chemically resistant, physically tough, and wearresistant. This process is an excellent choice for larger plastic partsproduced in short run or low volume production quantities.
Excellent flow ability allows molding complex geometry including: louvers, ribs, bosses and openings
Superior cosmetic appearance for visibly critical applications
Superb encapsulation ability
Polyurethane molded parts in 2-5 weeks
