Pierce & Cut Die Stamping is a very cost-effective way to quickly stamp flat, “rectangular” shaped parts such as shims, spacers, and plates. A benefit of Pierce & Cut Die Stamping is that raw material is better utilized reducing the total amount of scrap material produced over other stamping methods.

Parts are produced when the feed system pushes (strip or coil stock) of raw material into the Pierce & Cut Die; at each stroke or cycle a finished flat part will be cut off the end of the strip. This type of die requires that the raw material width is cut to the size needed for the part. The feed rate of the material is determined by the length of the part. Longer parts need more time per stroke to get the strip in position for the next stroke. Thickness also influences that feed rate. Thicker parts need the press to run a bit slower than thinner parts. Pierce & Cut Dies punch out holes and notches on the first stroke, and then the second and final stroke is the cut-off, where the completed part is cut from the strip. Once cut from the strip finished parts will be exit the die and will fall onto a chute or slider where they flow into the collection bin. The scrap is typically punched through the die and is collected under the press, or next to the press using chutes or slides.
