A malleable sheet of material is introduced into a progressive die system having a plurality of stations containing one or more dies for forming a predetermined configuration in the malleable sheet of material as the sheet progresses through the system. At least one strengthening means is formed along the sheet of material at an early station in the progressive die system for strengthening the sheet of material such that the sheet can be controlled at subsequent stations. Die related operations are then performed on the sheet of malleable material by the progressive die system until a completed part is created.
