Abstract
A stamping die is provided. The stamping die includes a die block, a punch, and a trap wall. The punch is configured to engage the die block in order to form a part from a sheet metal blank. The trap wall is secured to the punch and configured to restrict the flow of sheet metal into the die block during punch and die block engagement. The trap wall is adjustable with respect to the punch such that a trap wall adjustment alters the flow of sheet metal into the die block.
