ABSTRACT:
A flange forming process uses first and second stages. The first stage produces a partially formed flange on an article. The second stage forces the partially formed flange into a die so a stepped surface of a knockout punch that is disposed in the die, produces a predetermined can height such as the FFCH (Factory Finished Can Height) while the retaining die limits the outside diameter of the flange.
