Castable Resin

Functional Resins
VisualSmoothTransparent

Castable resin is composed of synthetic acrylate or epoxy-based polymers formulated to burn out completely at controlled rates, leaving minimal ash residue so molten metal can fill the void a pattern leaves behind. Unlike standard general-purpose resin, which leaves significant ash and expands aggressively when heated – often cracking the investment mold – castable resin is specifically engineered for low thermal expansion and clean combustion. It is generally more affordable than wax-based casting materials, though it doesn't replicate true wax's burnout behavior quite as closely. Castable resin suits jewelry, small metal parts, and precision components produced through investment casting.
