Reaction injection molding or RIM is the high speed production of polymer parts by quick injection of low viscosity reactive monomers or prepolymers into complex shape cavities. The trial and error approach, mostly employed in production nowadays, reflects the state of art of this relatively new process. Obviously, material and process parameters determine the 'moldability' of a specific system in a particular application. The concept of 'molding areas' on the critical parameters plane can be extended from thermoplastic injection molding (TIM) to reaction injection molding (RIM). These moldability diagrams are intended to give first guidelines for process optimization as well as directions for starting new materials and new mold cavities.
