Vacuum Casting
Cost-effective small series polyurethane parts with production-like properties
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
ABS-like
Strength: 45 MPa • Shore D: 80-85. Ideal for holders, housings and mechanical parts.
PC-like
Transparent • High impact. Perfect for transparent parts and light guiding.
PP-like
Flexible • Chemically resistant. Excellent for clips, hinges and flexible connections.
Rubber-like
