Reaction Injection Molding

Overview

Reaction Injection Molding systems combine two liquid components that chemically react in a closed mold to form a polyurethane plastic part. Unlike processes which require very high temperatures and pressures to melt and force plastic into a steel tool, RIM molding is an exothermic process, and the reacting urethane expands within the mold filling the cavity without external pressure while using significantly less energy.  Tools are machined out of aluminum for less expensive molds, shorter lead times, and greater flexibility in design and changes.
