Vacuum Casting
Description
Vacuum Casting is used to produce high-quality parts with detailed and accurate features, often mimicking the properties of injection-molded parts.
Materials Available
- Acrylonitrile butadiene styrene - ABS
- Polyurethane resin - PR700
- Polyurethane clear resin - 8744E
- Nylon
- Nylon+GF
- Polypropylene (PP)
Technical Details
