Abstract:A lot of theoretical analyses and repeated experience were carried out in the study of the forging process of cylindrical housing. Some important steps during the process were introduced, including the determination of the forging process, structure of the die and location of the die parting surface. The heating problem and the plastic pad which can avoid the raising of the die were introduced too. These have special significance in the precision forging process of aluminum alloy.

Key words: aluminum alloy isothermal precision forging assembled die heating range
