Deep drawing is a sheet metal forming process in which a sheet metal blank is radially drawn into a forming die by the mechanical action of a punch. It is thus a shape transformation process with material retention. The process is considered `deep` drawing when the depth of the drawn part exceeds its diameter. This is achieved by redrawing the p.....
