Single-process die only completes one stamping process in a pair of dies, such as blanking and punching, but there can be multiple punches or dies. However, parts with complex shapes need to be punched several times to meet the requirements of shape and size, which is not suitable for single-process dies.

Single-process die refers to the die that only completes one process in one stroke of the press. It can be divided into blanking die, bending die, drawing die, hole turning die and forming die. Single-process mold makes the mold simple to manufacture and convenient to maintain.
