Delivering Excellence in Reaction Injection Moulding (RIM)
Reaction Injection Moulding (RIM) is the injection of a precisely proportioned mix of chemicals into a mould. The mould is manufactured from polymer resin or cast- or CNC-machined aluminium. The material sets by chemical reaction.
By the selection of ingredients, RIM mouldings can range from soft and highly flexible to hard and highly rigid. By the inclusion of a blowing agent, RIM can produce flexible or rigid foams. Foams can also be formulated to have an integral skin for a decorative or functional finish.
By spraying the mould prior to the moulding process it is possible to produce an entirely different surface colour and/or flexibility than the main form of the moulding.
RIM mouldings can incorporate moulded-in components in metal or other materials.
