WebLow-pressure tube hydroforming begins with a tube whose circumference is slightly less than the final circumference of the finished geometry. Tube pressurization occurs after placing the tube in an open die, prior to closing. As the die closes, the circumference of the tube changes shape to conform to the closing die. WebTube hydroforming is an innovative forming process in which the tube is pressurized by a fluid medium and formed into a complex shape. There are two types, low and high pressure hydroforming. In the high pressure process, the tube is expanded by an internal pressure to fill the die cavity.
