Extrusion International 6-2017

17 Extrusion International 6/2017 Inoutic, based in Bogen / Bavaria, a German subsidiary of the Belgian Deceuninck group, has just ordered a coextrusion solution from its long-standing machine supplier battenfeld- cincinnati. Within only one year, the profile manufacturer has decided for the third time to upgradeandextendanexistingmonoextrusion line and to transform it into a coextrusion line, foroptimal responsetocurrentmarketdemand. Inoutic ranks among the leadingEuropeanmanufacturers of energy- efficient profile systems for windows, doors and roller blinds. Its product portfolio also includes terrace systems aswell as facade and roof claddings made of Twinson wood-plastic composite and PVC. Since sustainablemanagement 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. Coextrudedprofiles offer the ideal option to combine amod- ern, impeccable surface with a core made of regrind, thus creating a sustainable product. For several years now, the Bogen based company has been rely- ing on profile extrusion lines from the German-Austrian machine manufacturer battenfeld-cincinnati. These aremono extrusion lines equipped with sturdy parallel twin screw extruders. To include co- extruded products to the portfolio, three of the existing extrusion www.inoutic.de www.battenfeld-cincinnati.com PROFILE EXTRUSION lines have now each been extended by adding a 63 mm coextruder from the conEX series. The geometries of the screws inside the ex- isting mono extrusion lines were also optimized for coextrusion by adjusting them to the required lower output rates. After the first extensionwas already installed at the beginning, and the second in the middle of this year, delivery of the third, identical model is planned for the end of the year. Norbert Prokopec, Man- ager Operations Central Europe, is very satisfied with the upgrade: “Only by a joint effort can unconventional ideas lead to positive results.” This is his way of expressing special praise for the success- ful open cooperation with the machine manufacturer, with whose help itwas possible toachieveoptimal utilizationof the existingma- chinery and spatial capacities. To take account of the limited space available, the coextruderswere placed in piggyback configuration on themain extruders. The coex- truders are fastened to the floor with linear guides so that they can be moved easily forwards and backwards. This gives the processor maximumflexibility and facilitates cleaning andmaintenance work on the main extruder. All screws, both the new ones for the main extruders and those for the conical coextruders, not only come with molybdenum coating on the screw flights, which has been tried and tested for many years, but with additional BC coating, which provides a unique level of anti-wear protection. Especially in processing PVC regrind or abrasive materials such as wood-plastic composites, this ensures high uptime rates and consequently cost- efficient profile extrusion.
