This design used piercing and blanking progressive die to form the products.The forming principle can be divided to two stages: First, piercing punch and die affect together and pierce two holes of1.85mm and two holes of6.5mm,then use the three holes as pinpoint to make the product formed.Key word Piercing and blanking progressive die Piercing punch Pr
