BU-U Urethane bending roll

Specialized machine for mass production of thin plate bending (Center adjustment is equipped)

Specialized machine for mass production of thin plate bending.

BU-U Urethane bending roll

  • High productivity and simple operation
    3000-4000 small piece work can be processed per day.
  • Excellent edge bending, roundness, and cylindrical.
    Flat plate, pressed work, work with hole, uneven work can be processed
  • No scratches on work
    aluminum, stainless steel, printed work can be processed.
  • Automatic deflection stopper
    When processing thin and long material by urethane roll, deflection appears on upper roll from pressurizing. Also deflection will be appeared in the center of work where forming pressure is not enough. However ISEL has controlled pressure to push the center of urethane roll by hydraulic system and solved this problem.(PAT.)

Urethane roll forming process

Steel cylindrical bending process by urethane roll is using the deformation of lower urethane roll ( urethane is melted on steel shaft )by pressurizing from upper roll (steal). Therefore work sheet is pressed and rotate between urethane roll and upper roll wtih pressure for processing. For changing work diameter size, it required to change upper roll diameter or installing the forming ring.

Small diameter processing / Large diameter

Small diameter processing / Large diameter


Suspension device

Suspension deviceSuspension device is proposed for the stability of forming ring and easy discharging of work, when large space between upper roll and forming ring. Also second pipe suspension device is for preventing small diameter work is not be processed twice after first processing.
