Reaction Injection Moulding

RIM casting is and ideal way to get low volume production. There are a huge range of materials available which have differing characteristics such as flame ret ardency or high temp etc. Typical Tool life can be 50 shots and quick de moulding times giving a cost effective method of producing large scale models with a quick turnaround.

For the models pictured we have made SLA masters which have been painted with a light spark finish. We then place these in silicone to make the tool which solidifies overnight and once hard the master can be cut out and saved for another tool. The cavity which is left can be cast into giving a copy of the original master. The parts are trimmed and fitted together ready for despatch.

Thread inserts can be cast during the process to allow the plastic to encapsulate the fully.
