One of the latest, most advanced cold bending techniques is stretch bending; a very accurate technique developed in the aerospace industry and used because of its benefits in product and surface quality.
Kersten is the first company that makes this bending method available for other industries as well.
Stretch bending technology is suitable for tubes and (extruded) profiles in aluminium, steel and stainless steel.
Kersten develops and manufactures its own special tooling to bend even the most delicate aluminium profiles without damaging the surface and with just minimal deformation of the cross section. Even if it concerns very small radii.
Stretch bending is complex and requires real craftsmanship. Recently Kersten invested in two highly advanced stretch bending machines of 200kN and 600kN.
