Abstract：

The characteristics of the hot stamping and super plastic inflatable compound forming process were analyzed. For realizing the fast superplastic technology scheme, a kind of special forming mould which integrated beading structure and seal structure was designed, and the hot stamping and super plastic inflatable compound forming process completed in the same set of mold was realized. According to the mould design and experiment analysis of the simulated test mould and a certain type of automobile engine cover, the forming part was obtained with no rupture, high uniformity of the forming thinning thickness and short time for forming, which can meet the reguirement of mass-production.
