True Cast Resin for High-Accuracy, Clean Burnout

True Cast Resin is a wax-filled material designed for precision casting of intricate jewelry to complex engineering components up to 5 mm thick. It delivers highly accurate parts with exceptional detail and smooth surfaces.

Engineered for reliability, quality, and versatility, True Cast Resin integrates easily into a wide range of burnout schedules. Low thermal expansion, minimal shrinkage, and 0.03% ash content ensure clean burnout and consistently excellent casting outcomes.

For fine wire filigree and lightweight jewelry, Castable Wax Resin is recommended to achieve optimal results. For large, demanding engineering parts, Clear Cast Resin is the recommended solution.
