Hydroforming Technology

Compared to traditional stamping processes, hydroforming offers significant technical and economic advantages-such as reduced weight, fewer parts and molds, enhanced rigidity and strength, and lower production costs-leading to its increasingly widespread application in industry, particularly within the automotive sector.
Reducing structural mass to conserve energy during operation has long been a goal in the automotive, aviation, and aerospace industries, as well as a key trend in the evolution of advanced manufacturing technologies. Hydroforming is one such advanced manufacturing technique designed to achieve structural lightweighting.
Also known as "internal high-pressure forming," the process utilizes a tubular blank. Ultra-high-pressure fluid is applied to the interior of the tube while axial force is simultaneously exerted on both ends to feed material into the deformation zone. Under the combined action of these forces, the tube material undergoes plastic deformation and eventually conforms to the inner walls of the mold cavity, resulting in a hollow component that meets all technical specifications regarding shape and dimensional accuracy.
