Abstract
A pressure sequence hydro-forming method is used to form an extruded structural tube. The extruded structural tube is placed in a hydro-forming die that is partially closed to compress the tube. The tube is filled with a hydro-forming liquid at a first pressure. The hydro-forming die is then closed and the pressure of the hydroforming fluid is increased as the hydro-forming die is fully closed. The pressure is increased to a second level of pressure to shape the tube into the desired part shape.
