For Jewelers, making jewelry needs Mold Frames. These frames are made from solid aluminum bar stock that won’t warp after repeated heating and cooling. Carefully milled surfaces are absolutely parallel and smooth. These vented frames allow excess rubber to escape, preventing model deformation when using natural rubber. Pre-drilled frame ends hold the sprue rod and formers perfectly centered during vulcanization so jewelers' model stays centered, ensuring a precision line-up with wax injector nozzles.
