Extrusion International 3-2022

42 Extrusion International 3/2022 Compounding Extruder Customized Production Lines for High-Tech Compounds Against the background of the booming e-mobility industry in China, the demand for high-tech compounds used in light-weight applications grows continuously. Reason enough for the chemical group Lanxess to substantially increase its compounding capacities in the People’s Republic. Lanxess opted for KraussMaffei Extrusion as the machine supplier for the Changzhou site and benefits from excellent German engineering services combined with efficient on-site support provided by KraussMaffei China in Jiaxing. “W e have designed, installed and already commissioned a high-performance turnkey com- pounding line for Lanxess’ Chinese production site in Changzhou,” explains Dieter Brunner, Key Ac- count Manager at KraussMaffei Extrusion GmbH. He proudly adds that “we have also been awarded the contract for the second line, which is scheduled for delivery in the course of 2022 and will increase the compounding capacity by an- other 30,000 metric tons per year.” Lanxess’ goal was to signifcantly expand production output of the two high-tech Durethan and Pocan plastics in China. With the installa- tion of the secondKraussMaffei line, the chemical group will achieve a total annual production capacity of 110,000 metric tons of compounds based on PA 6, PA 66 and PBT at its two sites in Changzhou and Wuxi. Customized production lines for high-tech compounds “In the case of the compounding line already in production at Lanxess in China, wewere responsible for the completeengineering– starting from the steel structure and all upstream and downstream components right through to the conveying systems to the fnished product silos,” says Dieter Brunner, who is not only very satisfed with the effcient coopera - tion with Lanxess but also with the High-performance turnkey compounding line fromKraussMaffei at Lanxess production site in Changzhou Lanxess produces PBT and PAcompounds with glass fiber weight fractions between 5 and 60 percent on the compounding lines in Changzhou, China Lanxess is responding to the increasing demand for PA 6, PA 66 and PBT from the Chinese e-mobility industry with the capacity expansion
