Abstract
A sheet metal material is stamped into a formed shape having a side wall between a central portion and a flange portion. The central portion is held between an upper pad and a die, and the flange portion is held between an upper binder and a lower binder. A post-stamping compression force is applied along a length of the side wall of the formed shape. For example, application of the post-stamping compression force includes moving the lower binder relatively toward the upper pad, such as by delaying a return of the upper pad during a portion of a return of the lower binder. During application of the post-stamping compression force, an outward force is applied against an inner surface of the side wall to insure any bowing of the side wall is in an outward direction.
