Abstract：The local squeezing process was applied to the back cover of heavy duty gearbox,and the local squeezing process was optimized in production,in order to solve the defects such as local thickness and large shrinkage holes of aluminum alloy die castings.The results show that local squeezing process can effectively solve the shrinkage defects of original castings.Through the verification of the best process,the qualified rate of the casting has been greatly improved.
