Tube hydroforming (THF) is ametal-forming process that uses a pressurized fluid in place of a hard tool to plastically deform a given tube into a desired shape. In addition to the internal pressure, the tubematerial is fed axially toward the die cavity. This process has various applications in the automotive, aerospace, and bicycle industries. Accurate coordination of the fluid pressure and axi...

High-pressure tube hydroforming is a promising method to deform the tubes in various shapes by bulging applying high internal pressure. However, challenges lie process itself, i.e., requires an expensive pump system and brings excessive thinning deformed part section. One option reduce required pressure solve these difficulties, other provide axial feed deformation zone thinning. due higher loa...
