ABSTRACT:
A press crown having a central plug characterized by having a greater stiffness than the surrounding transitional region connecting the plug to a plurality of lugs. The shape of the press crown transfers a significant portion of the deflection to occur in the transitional region. This substantially reduces the possibility of the deflection causing undesirable lateral forces to act upon the tooling apparatus.
