Urethane Casting

Urethane casting provides end-use, rigid, or flexible plastic parts with production-level quality. Built without expensive and time-consuming hard tooling, our urethane casting process uses a 3D printed master pattern and silicone molds to deliver high-quality, short-run parts up to 30” long. We’ve created this guide to give you tips on creating highly accurate parts with a wide variety of high-quality cosmetic finish options.
