Sheet hydroforming has many advantages and has gained increasingly attentions in the industrial fields of automotive,aerospace and aircraft etc. Focused on the industrial production＇s need, this paper addresses the definition and extension of the sheet hydroforming technology. Based on the proposed hydromechanical deep drawing without a draw die and the combined hydroforming method, some different processes are discussed and the major design points and the features of the products are investigated. The key process parameters in the sheet hydroforming are generalized and made explanation finally.
