Process Introduction

Reaction Injection Molding (RIM) is a low molding pressure process for production of complex plastic parts directly from low viscosity monomers or oligomers. Two or more reactive streams A and B are combined by impingement mixing in a self -cleaning mix head (10 to 20 MPa) prior to enter the mold. Mold pressures are very low (less than 1 MPa). With this process parts can typically be demolded in less than one minute.
