What is Deep Draw?Deep Draw metal forming is a complex process in which flat, sheet steel is formed into simple or more complex components. From a coil of flat strip metal, the material to be drawn is placed over a shaped die and pressed, in stages, with a punch.

Initial Stages: Blanking and Cupping
A circle or disc of sheet metal is first blanked from the coiled stock as the first station in the die. Then the flat blank is cupped around the nose of a punch and pressed into a die to form a cup.
Subsequent Stages: Drawing
During the drawing process, the metal is formed under pressure. Forces of tension (in the steel wall) and compression (in the shell flange) are induced as the steel is stretched by the “nose” of the punch into the die. These forces tend to thin the shell wall and thicken the shell flange. Depending on the length to diameter ratio, several draws may be required to create the basic shape of the part. In the drawing process several stepped diameters may also be created in the part. 
Final Part Configuration
A wide variety of in die stations can be developed to provide additional features. These additional features may include:coining, bottom piercing, multiple side piercing, extruding, embossing, marking, burnishing, ironing, chamfering, flange forming, shaped flange trimming, beading, reverse drawing, and rib forming.
