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
