Key points:
• Deep-draw stamping can be an economical alternative to machining large blocks of metal.
• Secondary operations such as piercing and grooving can be an integral, automated operation with deep drawing.
• Deep-draw stamping works for parts with variations in diameters and large, hollow areas.

A deep-drawn stamping can be more than a metal trash can. Metal blanks can be deep drawn to form complicated shapes of varying sizes.

Unlike the machining process, stations of the stamping press can incorporate secondary operations such as piercing, notching, coining, embossing, beading, and grooving. And the stamping process uses sheets of raw material instead of blocks of metal which can help reduce upfront costs.

However, the stamping process requires extensive metallurgic and process knowledge. For a 101 on deepdrawn stampings, here is a list of basic terminology and some examples of unexpected deep-drawn shapes.
