Rio Grande Mold Frame and Sprue Former System

This quality-made Rio vented mold frame includes a brass screw-in 1/8" sprue former/collet to center the sprue and provide an optimum sprue shape for the mold. After vulcanization, unscrew the sprue former from the frame to reduce torque and stress on your master model and to help you more easily remove the mold from the frame. Ideal for use with most wax injection systems.
