Manufacturing

Pressure-Sequence Hydroforming

  • Tube blank, three to ten feet long, one to six inches in diameter gets placed in the forming die
  • Tube is filled and pressurized with water
  • As dies close, pressure is gradually increased to shape the tube
  • Corners of the component are formed, retaining a constant wall thickness for exceptional structural integrity

  • Piercing is completed in the die
  • Access and mounting holes can be
    • Any shape
    • Any size
    • Any number
