Deep drawn metal stamping FAQs.


What is deep drawn metal stamping?

Drawing of metal into closed cylindrical shapes, that frequently have a depth greater than the narrower dimension of their opening, is one of the most widely used and important of all stamping processes. The process had its earliest uses in manufacturing eyelets for shoes, artillery shells and cartridge cases it is sometimes called shell drawing. When the depth of the drawn part is greater than its diameter, it is considered to be Deep Drawn Stamping.

Deep Drawn Progression

The control of wall thinning, buckling, and tearing of the metal present complex problems, that Twinplex engineers, designers and setup personnel recognize and are experienced in solving.

Generally several draws are required to bring a shell into the final desired shape and diameter. A wide variety of in press and auxiliary operations can be performed on the base shell to bring the end part into the final configuration specified (as seen below).
