Abstract
A tool pack is described that includes a redraw die, a first ironing die and a second ironing die. The tool pack may be incorporated in a bodymaker that has about a thirty-inch stroke to form a metal cup with a height to diameter ratio of about four. In some embodiments, the redraw die, the first ironing die and the second ironing die are situated in the body maker so that each reduces a sidewall thickness of the cup that is forced through the redraw die, the first ironing die and the second ironing die by a plunger by a predetermined amount to produce a cup that can be formed into a bottle-shaped container with low defect rates.
