The Die Face Engineering for the Stamping Die of Auto Cover

The main content of the modular surface engineering is introduced, in which the method of modular surface reconstruction was briefly analyzed from three aspects, Stamping surface, deformation compensation and defects elimination. The processing of stamping surface is described from drawing die, trimming die, flanging die and sizing die; deformation compensation from both bending and tensile deformation of the work piece; defects elimination from how to reduce the error by surface compensation. Modular surface engineering effectively reduces the difficulty and the time of mold test and improve the quality of mold. It is also significant to reduce the cost and cycle time of entire cover mold.
