LOW VOLUME AND PROTOTYPING SOLUTIONS

Why RIM?

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

Unlike the more conventional thermoplastic process of injection moulding, 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 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.

  • RIM enables production of parts of varying wall thickness and can incorporate inserts

  • Suitable for low production runs to 100s of parts with cost efficiencies above those of injection moulding

  • Tooling is considered cheaper than for injection moulding – especially with on-site tooling capability

  • Part consolidation is possible
