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.
