reaction injection moulding (RIM)

Ideal for large format or complex parts without full production tooling

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
