Urethane Casting Service

Low Volume, Durable Parts with Production-Level Quality

Urethane casting provides end-use, rigid plastic parts or rubber 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. The finished dimensions of urethane cast parts depend on the accuracy of the master model, part geometry, and casting material. In general, a shrinkage rate of + 0.15% is expected. Cast urethane parts are frequently used when color, surface quality, and toughness are required. Cast urethane is a perfect alternative for insert molding or overmolding in low volumes with diverse material choices.    Urethane casting parts can also be clear, color-matched, painted (including EMI shielding), have installed inserts, and even custom finished.

Proto MFG Urethane Casting services are more than just a molding process – it’s a team of highly skilled operators ensuring every step of the process goes smoothly, from pattern to cast to post-processing.
