Four bending technologies. One for your geometry.

Mandrel, mandrel-less, 3-roll and multi-radius.

The right technology depends on the radius, the material and the series you have to produce.

Buying guide

Which bending technology do you need?

Tube and profile bending covers several technologies that aren’t interchangeable with each other: the choice depends on the radius you need, the material’s wall thickness, and whether the tube can lose its cross-section during the bend. Confusing one technology with another usually results in out-of-tolerance parts or an avoidable tooling overcost.

01

Mandrel or mandrel-less

Mandrel bending introduces an internal mandrel that supports the tube wall, essential for tight radii and thin-wall tube. Mandrel-less bending does without that mandrel when the radius is wide enough for the tube not to ovalize, simplifying the tooling.

02

3-roll or multi-radius

3-roll bending machines are designed for structural profile and large-section tube with wide radii. Multi-radius bending machines let you program several different radii on the same part without repositioning it or changing tooling between one bend and the next.

03

Electromechanical, hydraulic or full-electric

Electromechanical drive offers precision in medium sections with contained energy consumption; hydraulic drive brings more force for thick walls; full-electric drive, typical of multi-radius bending, simplifies maintenance by doing away with the hydraulic system. No technology replaces another: it’s worth defining the radius and material first, before comparing drive types.
