The high manufacture precision of the brake shield with thickness of 2.5 mm and complicated shape used in electric-car was satisfactory using exact stamping technique.A feasible forming technique was framed,and one multiple process composite die was designed in order to accomplish the punching,extending,cutting and forging base on the analysis and account for the configuration and stamping technology of brake shield.The composite die structure,stamping process of brake shield and key point of die designing were introduced.The obtained moulds are permitted to be used in real production and the products are satisfactory.
