Abstract
A method of manufacturing a stamped, extruded finished part includes permanently attaching upper and lower shoes to a moveable ram and a stationary bolster plate of a dedicated stamping press. A replaceable extrusion die sub-assembly is mounted between the upper and lower shoes for extruding a workpiece into a preform. A component die sub-assembly is replaceably attached to the ram and bolster plate of the press for processing the preform into the finished part. The workpiece is progressively extruded then stamped into the finished part. Only the component die sub-assembly and the perishable components of the extrusion die sub-assembly are replaced when a different finished part is ordered.
