Deep Draw 101

A product design engineers guide to the Deep Draw metal stamping process

Deep draw technology (or, deep drawn stamping) is a process of cold forming a round or shaped flat blank into a desired form — without excessive wrinkling, thinning or fracturing. Parts are “deep drawn” if their length, after being drawn, is in excess of one-half of their diameter.

Sizes of deep drawn parts may vary from very small (less than 0.250”, or the metric equivalent) to very large (more than 12”, or the metric equivalent).

The material thickness of deep drawn parts has a large range. Some may have a wall thickness of less than 0.010”, while others may have a wall thickness greater than 0.125”.
