Notable Features: 
  • .125" (3.17mm) diameter cup shape with varying wall thicknesses.
  • Cup shape is formed with a precise (6 degree) outward flare within the tool progression.
  • Pedestal shape incorporated into the inside bottom of the cup.
  • A rare case of cold heading weldable aluminum into a complex morphology.
Advantages: 
  • Material waste is minimal.
  • The part is formed from small diameter material and the OD features are formed up.
  • No material removal is needed; scrapless. Machining methods would need to start from a large bar over 1/8" diameter and proceed with heavy material removal. Lots of scrap generated.
  • Stamping/deep draw would create scrap and add to cost.
  • Cold heading gives the advantage of varying the thickness of the wall throughout the morphology of the part (ie: the CROSS SECTION is able to VARY in thickness, ie: the side walls of the cup can be thin, the bottom can be thick, and features like the pedestal can be formed on top of the cup bottom).
  • No cut off tit issues occur with this forming process.
  • Surface finish is very good. No special finishing is needed to produce a high finish. The finish is in the tools.
  • Top surface of the cup walls is precisely flat to within tenths of a thousandth. This can be problematic in the stamping/deep draw process-not experienced in the cold forming method.
  • Production speeds are very high allowing for low production costs, especially on higher quantity piece parts.
