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
how it works
- Master pattern built (3D print of CNC)
- Silicone mould cast around the master
- PU resin poured under vacuum, bubble-free
- Captures fine detail and complex features
- Typical tolerances: +0.2 – 0.5mm
- Rigid, flexible, clear or coloured materials available
- Optional post curing to increase heat deflection properties
typical volumes:
Up to 25 parts per mould set
lead times:
1 – 2 weeks
(depending on quantity and complexity)
best suited for:
- Pre-production prototypes and market-ready samples
- Low-volume production (10-25+ parts per mould)
- Parts needing cosmetic quality or functional testing
- Bridge production before tooling investment
- Automotive, Medical, Industrial and Consumer sectors
