The deep drawing tool was produced to build a cup with a diameter of 49mm and a sheet metal thickness of 0.8mm. It consists of a drawing die, a punch and a blank holder, made of hardened tool steel. To prevent heat flor out of the sheet metal, the blank holder and the drawing die are covered with an isolation layer. At the area near the punch there is a protecting ring from tool steel with a diameter of 55mm which prevents the isolation layer from breaking, since it cannot withstand the shear stress during the drawing operation.
