Abstract:
A press punch for pressing a powder includes a generally cylindrical metallic body and a polyurethane layer disposed around the metallic body. The metallic body has a nominal outside diameter and a generally flat bottom face. The polyurethane layer is disposed around the metallic body such that a bottom of the polyurethane layer is flush with the generally flat bottom face of the metallic body and an outside diameter of the polyurethane layer is substantially the same as the nominal outside diameter of the metallic body. In another embodiment, the outside diameter of the polyurethane layer is greater than the nominal outside diameter of the metallic body.
