The document discusses using DirectTool to create prototype stamping dies for metal parts. A Ford Motor Company project used DirectTool and DirectMetal 20 to produce stamping tools in only 2.5 days, requiring just 33 tons of force to stamp 8 parts per tool without any tool deformation. The tools were used to stamp strengthening brackets for car doors from 2.5mm mild steel sheet.
