High stability where it is really needed and softness wherever possible – that is VarioSection®. The tool cross-section and thus the profile cross-section is modified during the ongoing extrusion process. This results in a continuous profile strand with seamless, smooth transitions between functionality and visibility areas with varying thickness. It is no longer necessary to join or rework several individual strands in order to incorporate the various sections into one whole strand. VarioSection® can even make the use of forming tools superfluous: even on very sharp bends such as the corner of a door, VarioSection® maintains a perfect and secure “cornering” thanks to its flexible bend radii and modified outer and inner geometry.
