Wire drawing. Drawing is a plastic processing that involves passing the material, in the form of bars of different sections, wire rods or bars, through a die or spinneret [fig. 1], consisting of a steel plate provided with a series of calibrated flared holes gradually decreasing in size, so modifying its section until it reaches that desired.

2019-3-12 · IMPACT EXTRUSION VS. DEEP DRAWING . Impacting is preferable to drawing when (1) the shell length is more than twice the diameter, (2) the base must be thicker than the side walls (i.e., having a heavy complex bottom), (3) the design incorporates lugs, bosses, projections, or recesses, and (4) the shell length requires several "draws."
2020-10-22 · Deep drawing The basic design of deep-drawing tools is as follows: » drawing punch » blank holder » draw die The strain on the drawing punch largely arises due to pressure. The blank holder and draw die are subject to wear mainly on the edges. Bending/folding When bending or folding, there is essentially no change in sheet thickness.
