What is Cast Urethane?
Cast urethane uses a 3D-printed master pattern to create a soft mold, typically of silicone. Polyurethanes are injected into the mold to fabricate parts. These can range from rigid to flexible and rubber-like. The soft mold is able to capture small surface details, thus enabling an accurate production of parts with a consistent quality.
Cast Urethane is ideal for small to mid-scale runs of end-use parts or prototypes for market testing. Compared to traditional injection molding, the tooling cost for cast urethane is less expensive and its lead time is much shorter. Parts can be finished in a variety of colors and produced from a wide selection of materials.
