Curve Bending

Along with 3D rotary tension bending, we offer free-form bending for diameters from 3 to 219.1 mm, with our without an inner mandrel. Bends with a radius as small as 0.5 times the outside diameter and any desired bend angle can be produced using cold bending.

 

Curve bending

  • Several successive bends with different radiuses produced in a single operation.
  • R min = approx. 4 times the diameter of the input material
  • R max = infinite.

 

Radius bending
with or without mandrel

  • A bend with a defined radius is formed in a single operation.
  • R max = approx. 1,000 mm


 

Die bending

  • A bend is formed in a single operation by a closing die.
  • R min = less than 1.0 times the diameter of the input material
  • R max = infinite.



Cryogenic bending
mandrel-free

  • The mandrel is replaced by a medium.
  • R min = 0.8 times the diameter of the input material
  • R max = approx. 1,000 mm
