Abstract：

The application of nested process for Ushaped parts and many small stamping parts in automobile was introduced, and the product modeling requirements, process requirements, die arrangement and precautions, and advantages of application were explained. Then, six stamping parts produced by drawing+(trimming, piercing)+(trimming, piercing and cutting) were obtained by nesting four small stamping parts into the complementary die surface of two Ushaped stamping parts, and six processes of the original process were improved. Therefore, the development costs of die, the number of operators and the punching costs of stamping parts were reduced, and the material utilization and die process ratio were improved. The results show that the development costs of die save 30000 yuan, the material utilization rate increases from 44.1% to 48.9%, the blank is saved as 0.4 kg every single press, and the development costs of white body stamping parts are reduced too.
