Deep drawn sheet metal part

Different materials have different tensile properties. The limit of elongation, that is, the proportion of blank diameter to stamping diameter. Stainless steel materials are controlled from 2.1 to 2.2 and carbon steel is controlled from 2.15 to 2.5. Stainless steel can be drawn a second time after deep drawing, but unlike carbon steel, stainless steel cannot normally be drawn to the same degree as the first, unless heat treated. Stainless steel equipment requires one to two times the strength of carbon steel equipment. Generally speaking, deep drawing using double - action hydraulic equipment is the best.

When choosing an oil, two factors should be considered.

1) An oil film should be provided to prevent scratches and reduce friction.

2) And after the completion of the deep drawing operation, to be able to facilitate and completely clear.

May include chlorinated or vulcanized oils or waxes, heavy duty emulsions, or deep drawn soap solutions
