Reaction Injection Moulding

When you need medium to large, durable, flexible (or rigid), lightweight parts with thin walls and intricate detailing, reaction injection moulding (RIM) provides a flexible and cost-efficient solution.

Unlike the more conventional thermoplastic process of injection molding, RIM utilises low-viscosity liquid polymers in thermoset processes. The polymers are injected into a heated mould, where they expand, thicken and harden. This process allows for fine detailing in design to be accommodated; and surface finishes are so good, part finishing times are drastically reduced. Moulds and tools can be created using reinforced silicones, epoxy resins, GRP, or machined from composite materials. The processes allow for over-moulding.

Using our RIM facility for producing high quantities of niche parts gives you access to an experienced team dedicated to delivering unrivalled levels of service and perfect parts on time, every time.
