In addition to the standard drawing processes, there are a number of additional metal stamping processes that can be employed within the press to generate additional features on the finished metal part. These additional metal stamping processes include:

  • Side Piercing: In the side piercing process holes are pierced in the side wall of the drawn part. The holes may be round or shaped according to specifications.
  • Bottom Piercing: In the bottom piercing process a round or shaped portion of metal is cut from the drawn part.
  • Beading: In the beading process, metal material is displaced to create a larger, or smaller, diameter ring of material beyond the original body diameter of a part.
  • Bulging: In the bulging process a portion of the part's diameter is forced to protrude from the surrounding geometry.
  • Coining: In the coining process material is displaced to form specific shapes in the part. Typically coining should not exceed a depth of 30% of the material thickness.
  • Curling: In the curling process metal is rolled under a curling die to create a rolled edge.
  • Extruding: In the extruding process, after a pilot hole is pierced, a larger diameter punch is pushed through, causing the metal to expand and grow in length.
  • Ironing / Wall Thinning: Ironing is a process to reduce the wall thickness of parts. Typically ironing should not exceed a depth of 30% of the material thickness.
  • Necking: In the necking process a portion of the part is reduced in diameter to less than the major diameter.
  • Notching: In the notching process a notch is cut into the open end of the part. This notch can be round, square, or shaped.
  • Rib Forming: Rib forming involves creating an inward or outward protruding rib during the drawing process.
  • Stamping / Marking: This process is typically used to put identification on a part, such as a part number or supplier identification.
  • Threading: Using a wheel and arbor, threads are formed into a part during this process. In this way threaded parts can be produced within the stamping press.
  • Leak Testing: Finished parts can be tested for leakage using a pressure-decay system.
