Low Volume, Durable Parts with Production-Level Quality
Urethane Casting
Urethane casting provides end-use, rigid plastic, rubber, and silicone parts with production-level quality. Liquitac is a leader in urethane casting services with domestic (US-based) and international economy options to fit your timeline and budget. Urethane gives professional results for low-volume production using a soft-tooling approach. The urethane casting process uses a 3D printed master pattern and RTV silicone molds to deliver high-quality, short-run parts up to 30â 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 typical.
Cast urethane parts are ideal when color, surface quality, and toughness are required for quantities from one to one hundred. Urethane molding is a perfect alternative for insert molding or overmolding in low volumes with diverse material choices. Polyurethane or silicone casting can bridge production between a 3D printed rapid prototype and an injection molding with a balance of quality, cost, and time. Urethane cast parts can be clear, color-matched, painted (including EMI shielding), installed inserts, and custom finished.
