Deep drawing manufacturing technology is stretching sheet metal stock, commonly referred to as a blank, around a plug. Rings restrain the edges of the metal blank, and the plug is deep drawn into a die cavity to achieve the end shape that is desired. Many shapes can be made through deep drawing and stamping, such as cups, pans, cylinders, domes & hemispheres, as well as irregularly shaped products.

The deep-drawn process is ideal for making parts such as wear rings and escutcheons out of stainless steel for the hot tub industry and Sierra cups and cups for carbide grinding tools. There are many other applications for this process as well.
