Innovative flexible production line for the manufacture of thin-walled quality tubes

Continous throughput
The tried-and-tested Flexistar concept is a high-quality pattented tube production line for thin-walled material.

Variable
As a compact tube production center in one system - combining multiroller and laser welding equipment - Flexistar does not require any change parts when changing length or diameter. This enables the production of two different diameters in alternation (e.g. inner tube - outer tube), as required for insulated chimney tubes or multi-layer bellows.

Modular automation
On the infeed side, the sheets can be fed from stacks or a coil. Automatic inline quality control can be integrated with ease.

Tube end processing
Tube end processing options include expanding, beading, flipping, shrinking, etc.
