Extrusion International 3-2022

43 Extrusion International 3/2022 excellent support provided by his Chinese colleagues. “This project is an impressive example of the fruitful cooperation between KraussMaffei Extrusion inHan- nover and our Chinese colleagues, especially against the background of fast local response times, cultural differences and language barriers.” The frst com - pounding line delivered by KraussMaffei is equipped withaZE110UT twin-screwextruderIn the caseof the second line, again a package solution, Lanxess opted for a ZE 98 twin-screw extruder from the BluePower series. The decision in favor of the ZE BluePower ex- truder was made after having carried out compound- ing tests with specifc Lanxess material formulations at KraussMaffei’s R & D center in Hannover. Dieter Brunner and his team are extremely pleased that ”the extraordinary compounding results as well as the unparalleled extruder performance combined with low energy consumption convinced Lanxess to choose the ZE Blue Power solution“. Ideally prepared for the production of different compounds On the lines supplied by KraussMaffei Extrusion, Lanxess produces PBT and PA compounds with a glass fber weight percentage ranging between 5 and 60 %. These compounds are mainly used in the booming Chinese e-mobility industry. An optimized set of screws is available for each of the two matrix materials – polyester and polyamide – which only needs to be exchanged in the event of a production changeover thus minimizing set-up times. Just like the frst production line, the second line will also be provided with an optimized wear protection as well as with versatile metering stations, side feeders and degassing units, so that a wide variety of formula- tions can be processed without any problems.
