采用温挤压制坯与温冲压成形相结合的近净成形加工技术，对壁薄且外形复杂的2a12铝合金小型外壳体进行精密成形加工。
Put forward the near-net-sharp forming process of warm extrusion and warm stamping to manufacture the precision forgings for the thin-wall shell bodies made of 2a12 aluminium alloy.
对挤压制坯、开式终锻成形进行了有限元模拟。模拟结果显示，挤压毛坯能正确成形锻件；
The extruding forming and finish die forging were simulated, and the simulation results show that the backward extruding blank is right and can form forgings;
