ABSTRACT

A system for forming a steel material includes a first binder, a second
binder, a punch and a carrier blank. The first binder and the second binder
are configured to form a draw bead shape in the steel material by compressing
the steel material between a draw bead protrusion and a draw bead channel. The
punch is configured to form the steel material relative to the first binder
and the second binder. The carrier blank is positioned on a surface of the
steel material and is configured to cover a portion of the draw bead shape
during formation of the draw bead shape in the steel material.
