reaction injection moulding (RIM)

Small, medium and large production-quality parts with flexible design freedom

what we offer

Pro2Pro’s Reaction Injection Moulding (RIM) service provides a fast, cost-effective way to produce small to large polyurethane parts — ideal for multiple prototypes or low-volume production. Using soft tooling methods (including aluminium, silicone, and resin-based moulds), we deliver structural or cosmetic components quickly, even when timelines and budgets are tight.

why customers choose us

  • Cost-effective for large-format parts.
  • Strong, durable PU materials with Carbon Fibre options for strength critical parts.
  • Complex geometries without heavy tooling investment.
  • Excellent surface finish and paint-ready options.
  • Rapid lead times.

how it works

  • PU resins injected into a closed mould.
  • Materials react and cure in-mould. Post process options for high heat deflection.
  • Produces rigid or flexible parts.
  • Lower tooling pressure — ideal for bigger, complex shapes.
  • Smooth, textured, or paint-readyfinishes available.

Typical volumes:

10-500+
(depending on tool material)

Lead times:

Approx. 2-3 days (small RIM tool)
Approx. 3-4 weeks (large or complex tools)

best suited for:

  • Large format or complex parts without full production tooling.
  • Multiple prototype iterations before finalising design.
  • Panels, housings, and structural components.
  • Short-run production where speed and flexibility are key.
  • Automotive, Off-highway, Agricultural, and Industrial sectors.
