Urethane Casting
How it Works
(Poly)Urethane casting is a method of manufacturing custom parts that are made by injecting urethane into a silicone mold. Molds are made by 3D printing a master pattern(s), then using those patterns to create cavities which we then pour silicone or urethane into.
What Can You Make?
You can urethane or silicone cast almost any shape in our custom molds. We have fabricated fully functioning medical prototypes to clear overmolded components used for military and scientific applications.
