Simultaneous stretching and bending during the straightening process serves to regulate material parameters like yield strength and elongation and reduce internal stress. As a result, deformities like corrugation, cross bow, length bow, or strip sabre are minimised and the strips’ deep drawing properties and geometrical precision optimised.

Our new stretch-bend lines straighten and flatten precision strips and foils with tensile strengths up to 2,200 Nm², and also optimise their mechanical properties.

This quality enhancement provides considerable advantages for the strips’ downstream processes.
