Existing stamping methods generate scrap material. Stampings done on progressive dies (Figure 1) require. timiig holes (l), separate from the actual part, that are used to locate the part in the die. The material used to make the timing holes (2) is eventually scrapped.

STAMPED PART WITH INTEGRAL PROGRESSIVE DIE TIMING HOLES (PUBLICATION ARTICLE)

by Jose Villanueva and Willie Kottke

  Existing stamping methods generate scrap material. Stampings done on progressive dies (Figure 1) require. timiig holes (l), separate from the actual part, that are used to locate the part in the die. The material used to make the timing holes (2) is eventually scrapped.

The new method (Figure 2) eliminates the waste.

Timing holes (3) are integrally formed within the part, saving material that would have previously been scrapped. These integral timiig holes are incorporated into the first stamping operation (4) so that they can be used to move the strip through the stages as well as locate the part during each stage.
