vacuum casting

High-quality polyurethane parts for prototypes and low-volume production

what we offer

Pro2Pro’s Vacuum Castingservice delivers high-detail, moulded-quality parts without the cost of hard tooling. Using Renishaw vacuum chamber systems, we eliminate air bubbles for superior part quality compared to traditional RIM processes – ideal for detailed, cosmetic and functional prototypes.

why customers choose us

Injection moulding-like surface finish and flexible material options
Wide PU material range closely simulating thermoplastics (vs RIM)
Short lead times
Ideal for visual models, fit testing and low-volume runs
Multiple surface finishes available
