Bending & Punching , using a machine presses or Stamping Presses for large series and mass production. 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 flange region (sheet metal in the die shoulder area) experiences a radial drawing stress and a tangential compressive stress due to the material retention property. Die cutting is the process of using a die to shear materials, such as sheet metal rubber, foil , plastics, foam
