In the automotive industry and aviation, aerospace and other fields, reducing structural quality to save energy in operation is a long-term goal and one of the trends in the development of advanced manufacturing technology. Hydroforming is an advanced manufacturing technique for achieving lightweight construction.
Hydroforming is also called "internal high pressure forming". Its basic principle is to use a pipe as a blank to apply an ultra-high pressure liquid inside the pipe while applying axial thrust to both ends of the pipe blank to feed. Under the joint action of the two external forces, the tube blank material is plastically deformed and finally adhered to the inner wall of the mold cavity to obtain a hollow part whose shape and precision meet the technical requirements.
