Schüco Polymer Technologies KG, a longtime KraussMaffei Berstorff customer, will be commissioning a coextrusion combination in the twin strand at the Weißenfels plant early this year. In this project, a KMD 114-32/P twin-screw extruder, which has been running for more than ten years, has been integrated into a new coex combination, which is also equipped with two KMD 63 K/P conical machines.
Robust 32D extruder modified for cost-effective and high-performance coextrusion
“With our concept of twin-strand coextrusion, we have met a special requirement from Schüco,” says Marc Stramm, sales representative for Germany at KraussMaffei Berstorff. “The machine, which has been in operation as a single extruder for more than ten years, has been integrated into the new, efficient and high-performance twin-strand extrusion machine that produces coextruded window profiles with a high output of 700 – 800 kg/h,” Stramm continues. The main extruder prepares the material with a higher proportion of recycled or filler content for the inner layer. The two coextruders (executed as a piggyback model) deliver the outer layer in the twin strand with performance of up to 200 kg/h per strand.
With the implementation of the C6 control system, the machine is state-of-the-art in terms of control and monitoring. Reliable production is guaranteed, especially regarding extruders produced in cooperation and downstream units.
“We have been using twin-screw extruders from KraussMaffei Berstorff for profile extrusion for many years,” emphasizes Joachim Papenheim, Supply Chain Manager at Schüco Polymer Technologies KG. “The machines are highly compact and robust and we are confident that the revised configuration will continue to manufacture in such a reliable, hassle-free and, above all, substantially higher-performance fashion,” explains Papenheim.
