A compound die can produce pierced blanks to close flatness and dimensional tolerances. A characteristic of compound die is the inverted position of the blanking punch and blanking die. The die is fastened to the upper shoe and the blanking punch is mounted on the lower shoe. The blanking punch also functions as the piercing die ,having a tapered hole in it and in the lower shoe for slug disposal.. Key word: Raised mold Concave mold Press tonnage
