Abstract: Sheet hydroforming has become an effective method in the material manufacturing fields because of its many advantages. A new metal forming method of drawing with two-sided pressure was investigated in this paper, in order to deal with the problem of the defects in asymmetric cylindrical part processing. This method exerts liquid pressure on the upper sheet surface coordinating with the counter pressure. The upper pressure can offset the pre-bulging which is suited for forming complex shape parts such as cylindrical and semi-ball cup. The results showed that pressure increased, and the single drawing ratio 2.2 was achieved by drawing with two-sided pressure compared with 1.9 in traditional forming.
