Aluminum profiles can be bent with the same equipment as for other metals. At large radii bending can be performed in hardened condition but at small radii you usually bend in soft annealed or in T4 condition (semi-cured). After bending it is possible to anneal to full strength.

Bending should accur before anodizing if demands are made for completely anodizing layer without cracks. Already at the profile construction you should take into account that the profile will be bended. At larger volumes and material in T4 condition you should not produce too large series, as there is a risk that the material remains and thereby there is a risk for self curing.

The most common methods for bending that we can offer are:

  • Tensile bending
  • Stretch bending
  • Roll bending
  • Press bending
