Abstract：

The technique of superplastic extrusion of lock core with cross-shaped groove are researched in this paper. The results show it is a feasible and effective process technology to produce thelock core with cross-shaped groove by using superplastic forming technique. The formed parts accordwith the design demands. The technique has higher productivity, utilization ratio of materials, and lowercost of production.
