The ongoing optimisation of our Stretch-Bend-Leveling line has made B+S to a global market leader for the leveling of thin and extremely thin metal strips.
By overlapping tension and bending during the levelling process, material parameters such as yield point, elongation and spring bend limit can be adjusted and internal stresses reduced. Shape deviation of the strip like waviness, transverse curvature, longitudinal bow and strip camber are reduced to a minimum.
These quality improvements of the strip improve processing considerably. This in turn improves deep drawing properties of the strips, shape accuracy of the end products is enhanced and the layer thickness of surface coating can be thinner.
