Polyurethane Casting
Overall, casting polyurethane is similar to injection molding. A mold, usually made of silicone or a similar soft substance, is injected with hot polyurethane which is then allowed to cure. Since the mold is not as resilient as the metal molds typically used for injection molding, polyurethane casting is not typically used for large volume production. However, very complex and intricate products can be produced with this method. Urethane casting is ideal for prototypes, small custom projects, and single pieces.
