Clear Plastic Metal Mold Injection Pellets - 1 lb

These specialized plastic pellets are used in injection machines to create high-precision "plastic wax" patterns for jewelry casting. Unlike traditional wax these plastic patterns offer superior dimensional stability and a smoother surface finish for mass production. They are formulated for a clean 100% ash-free burnout in the furnace to prevent casting porosity in the final metal piece.

The pellets are commonly made from materials like HDPE or modified acrylic to ensure they can capture .01 mm details from the metal mold. Using these pellets allows manufacturers to achieve more symmetrical and uniform-weight pieces than traditional rubber mold methods.
