Reinforced Reaction Injection Moulding Machinery

Reinforced reaction injection moulding (RRIM) is an extension of RIM. Materials for RIM and RRIM are very similar, but the moulding processes are substantially dissimilar because of the differences in viscosity and 

The shaded bars represent properties relative to each other on the same comparative scale. Bar widths indicate range of costs, bar positions indicate relative costs, left-hand side indicates lower costs.

Lance-type cylinders should be used instead of other high-pressure metering pumps. Pumps are not able to meter the highly viscous materials without undesirable fibre breakage and excessive internal pump wear. 

Recirculation pumps are needed that can handle viscous materials and keep fibres in suspension.
