Vacuum casting
Cost-effective small series of polyurethane parts with production-like properties, through selected, certified partners
Vacuum casting process
Polyurethane parts. Vacuum casting is a cost-effective method for producing small to medium series (1-100 pieces) of high-quality polyurethane parts. The process uses silicone moulds cast from a master model.
Process advantages
- Low cost for small series
- Fast development (5-7 days)
- Excellent surface quality
- Complex geometries possible
- Various colours and properties
Technical specifications
Ideal for
Functional prototypes · Pre-series validation · Test models · Marketing samples · Bridge tooling.
Polyurethane materials
