The main function of the progressive model is getting the motor stator and rotor plate out at one time， reaching the goal of the utter use of material. The main characters of the progressive mold structure: 1. In the material guide system , bilateral plate mechanism and steel ball are included , with material in the plate medial continuous feeding, and the steel balls body poin
