Reaction Injection Molding

Reaction Injection Molding

Reaction Injection Molding (RIM) can produce strong, flexible, lightweight parts which can easily be painted. It also has the advantage of quick cycle times compared to typical vacuum cast materials. The bi-component mixture injected into the mold has a much lower viscosity than molten thermoplastic polymers, therefore large, light-weight, and thin-walled items can be successfully RIM processed. This thinner mixture also requires less clamping forces, which leads to smaller equipment and ultimately lower capital expenditures. Another advantage of RIM processed foam is that a high-density skin is formed with a low-density core. The disadvantages are slow cycle times, compared to injection molding, and expensive raw materials.

RIM tooling materials we normally used: Aluminum, ABS, Epoxy and Silicone Rubber.

The reaction injection molding‍ we offer at Honkia has varying wall thickness on one part to increase the efficiency of the product, also has no sink mark on the thick wall. It can mold over metal, glass, wood, wiring, circuit boards, hardware, etc. In case you are trying to looking for an economic solution for the low volume plastic parts with big size, reaction injection molding is the right choice as it features lower cost per-part for low volume production.
