Abstract：

The technology and die structure of support plates for left and right panels of auto door were introduced. By optimizing the technology and die structure, the support plates of left and right panels of the car doors were produced in one die including drawing, trimming, punching and cutting process. The optimized technology, the structure and principle of multi-position die were described. Production practice proves that the cost of die development is effectively reduced；the original six sets of die are integrated into a set of die, which reduces the cost of punching times and the number of stamping operation workers, improves the production efficiency, and saves the storage space of stamping workshop, increases the material utilization by 5.66% than that of the forecast sheet drawing. Therefore, the cost of development on the vehicle will reduced considerably.
