Mold Frame and Sprue Systems


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.

  • Country of origin : United States

Please Note: A screw-in 3/16" sprue former/collet is also available to create larger sprues.
