Deep drawing entails the cold forging of metal sheets, operations that allow the obtaining, without swarf removal and through plastic deformation, objects of the desired size and shape from sheets of metal material (e.g., steel, copper, aluminum or light alloys) of limited thickness.

Deep drawing is the most difficult operation of cold forging, but thanks to it, a flat metal sheet is transformed into a hollow body through one or more phases. During this operation, the material is subjected to considerable tension and compression efforts that change the position of the metal fibers. For this reason, it requires the use of quality metal sheets. Deep drawing operations are often flanked by bending activities, operations by which it is possible to obtain objects of various shapes without changing the thickness of the sheet.
