Abstract：

It is introduced the multi-position progressive die design of auto interior parts. Then, the stamping forming process of part was numerically simulated by software Dynaform, and the defects of part were predicted accurately. According to the bending characteristics of parts at different positions and angles, two bending middle processes were added, and the 11-position layout design including blanking and bending were finally determined by multi-bending to make all stamping areas unrestricted in stamping directions so as to avoid interference. The actual production proves that the multi-position progressive die is compact and reasonable, and the quality of parts is stable with high efficiency to meet the needs of mass production.
