Abstract
A method of forming a can end comprises the step of forming a substantially circular metal blank having a periphery and a center panel. An annular recessed panel is subsequently formed in the blank. The recessed panel has a first depth in relation to a substantially annular portion of the blank contiguously formed with the recessed panel. The substantially annular portion of the blank is then coined while the recessed panel is re-formed to a second depth in relation to the substantially annular portion of the blank. The second depth is greater than the first depth. Forming the can end in this manner minimizes warpage of the can end, and thereby allows the can end to be formed from a relatively thin sheet of metal.
