DEEP DRAWING - The process of cold working or drawing sheet or strip metal blanks by means of dies on a press into shames which are usually more or less cup-like in character involving considerable plastic deformation of the metal.

Deep drawn metal stampings have several advantages. These parts stamped from a flat strip of material (stainless steel, copper, aluminum, etc.) and through a series of die sets drawn or stretched into a cup or tube shaped part. One advantage is the ability for the final part to be seamless. Other advantages of deep draw metal stamping include nearly limitless O.D. to I.D. combinations, different shapes other than round stampings, and better control of part dimensions.
