Cast Urethane is a manufacturing technique to make high-quality cosmetic and functional parts produced in a production-like material quickly and inexpensively before proceeding to injection-molding.
Process
- Parts can be made in less than 10 days
- Silicone RTV tools have 20-30 shots
- Master tools made from additive or CNC
