Profile manufacturer invests in coextrusion INOUTIC, a German subsidiary of the Belgian Deceuninck group, has ordered a coextrusion solution from machine supplier battenfeld-cincinnati. For the third time within a year, the profile manufacturer has decided to upgrade and extend an existing mono extrusion line and to transform it into a coextrusion line, for optimal response to current market demand. the open cooperation with the machine manufacturer, with whose help it was possible to achieve optimal utilisation of the existing machinery.

Taking account of the limited space available, the coextruders were placed in piggyback configuration on the main extruders. The coextruders are fastened to the floor with linear guides so that they can be moved easily forwards and backwards. This gives the processor maximum flexibility and facilitates cleaning and maintenance work on the main extruder. All screws – both the new ones for the main extruders and those for the conical coextruders – have molybdenum coating on the screw flights, with additional BC coating, which provides enhanced anti- wear protection. battenfeld-cincinnati – Germany Website: www.battenfeld-cincinnati.com Inoutic/Deceuninck GmbH – Germany Website: www.inoutic.de

The company has been relying on profile extrusion lines from battenfeld- cincinnati for several years. The mono extrusion lines are equipped with sturdy parallel twin-screw extruders. To include coextruded products in its portfolio, three of the existing extrusion lines have now been extended by adding a 63mm coextruder from the conEX series. The geometries of the screws inside the existing mono extrusion lines were also optimised for coextrusion by adjusting them to the required lower output rates. Norbert Prokopec, manager operations Central Europe, is satisfied with the upgrade, expressing praise for

Inoutic manufactures energy-efficient profile systems for windows, doors and roller blinds. Its product portfolio also includes terrace systems as well as facade and roof claddings made of Twinson wood-plastic composite and PVC. Since sustainable management of existing resources is a top priority for the company, the profiles it produces are not only recyclable, but also to an increasing extent made of recycled PVC in the first place. Coextruded profiles offer the option to combine a modern surface with a core made of re-grind, creating a sustainable product.
