Reaction Injection Molding

Reaction Injection Molding (RIM) is a new process for the production of large parts in large runs. In the RIM process, a monomer or pre-polymer (PU derivatives) in a liquid state is poured using a dosing pump into the mold head.

The mixture is then injected into the mold at a low ambient temperature and pressure, the crosslinking and curing begin quickly, and after 10 minutes the figure will already be solidified, being able to be removed from the mold.
