Metal sheet metal hydroforming technology refers to the use of liquid medium instead of concave or convex die, which can forming a process by the pressure of liquid media sheet.
The advantages of hydroforming sheet metal:
(1) Increase the forming limit, reduce the number of forming passes, reduce tooling number, and reduce costs.
(2) The sheet hydroforming technology can improve the surface quality of the product. Compared with the traditional drawing process, hydroformed parts have higher geometrical dimension accuracy, higher material utilization, less rebound and better residual stress distribution.
(3) Hydroforming technology has many advantages such as light weight, cheap price and complex geometry.
