Why Choose True Cast Resin?
Castable Resin Formulated for Reliable, Precise Casting of Detailed Patterns
Designed for Consistent, High-Quality Casting
Crisp features, smooth surfaces, and superior accuracy enable highly detailed cast parts.
Reliable Printing and Forgiving Casting
Printed parts have low thermal expansion and maintain surface integrity with no wax migration or residue over time, allowing for a more forgiving casting experience.
Clean Burnout
With 0.03% ash content and low shrinkage, True Cast Resin delivers a clean burnout that integrates easily into existing investment casting workflows.
Versatile Casting Applications
Cast intricate jewelry patterns, heavy jewelry, and complex engineering components up to 5 mm thick.
Applications of True Cast Resin
True Cast Resin delivers precise, high-quality cast parts with crisp features, smooth surfaces, and clean burnout, making it ideal for a wide range of demanding casting applications.
Consider True Cast Resin for:
Post-Processing
Form Wash (2nd Generation) Settings
5 min in IPA
Parts should be washed for 5 minutes in IPA or ethyl alcohol (concentration of 91% or higher). Immediately afterwards, dry the part thoroughly using compressed or forced air. Spray (or rinse) parts with fresh IPA or ethyl alcohol, then dry again using compressed or forced air.
Form Cure (2nd Generation) Settings
3 min
Ambient
It is highly recommended to cure parts - this will significantly reduce any potential defects during casting. Cure for 10 minutes without heat in Form Cure or equivalent third-party curing machine. Cure for 3 minutes without heat in Form Cure (2nd Generation).
