Abstract: Provided is a process of making an aluminum bottle, the process including: obtaining sheet aluminum, the sheet aluminum having a difference between ultimate tensile strength and yield strength between 3.31 thousand pounds per square inch (ksi) and 8.0 ksi, and the sheet aluminum having a yield strength between 33.1 ksi and 42 ksi; cutting a blank from the sheet aluminum; plastically deforming the blank into a cup with three or fewer drawing steps; and necking the cup to form an aluminum bottle with a neck.

Abstract: A draw pad reduces instances and the extent of earing when a blank of metal is clamped and punched during a drawing process that results in the formation a cup-shaped body from the blank. A draw pad for a cupping press includes an inner surface that defines a draw aperture that is configured to receive a punch. The draw pad also includes a clamping surface that has a first force concentrating segment disposed circumferentially spaced apart from a second force concentrating segment, where each force concentrating segment includes a first arcuate groove and a second arcuate groove that is disposed concentric and radially spaced apart from the first arcuate groove.

Abstract: A low-spread metal elongated bottle and its production method are described for reducing rejection rates associated with the production of metal bottles at high speeds. The elongated bottle includes a sheet metal formed body. The sheet metal has a low spread between a yield state corresponding to the yield stress of the sheet metal and an ultimate tensile state corresponding to the ultimate tensile stress of the sheet metal. The body further includes a concave bottom portion having a circular perimeter. A cylindrical portion extends from the circular perimeter of the bottom portion and has a uniform diameter. A neck portion extends from the cylindrical portion and has a tapered profile. The neck portion may include a threaded portion including threads exposed on the outer surface of the neck portion or an area for crimping of a crown.

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.
