Successful userXinli produces plastics for the automotive and electrical industry on a ZE Performance twin-screw extruder.
“Since we began using the new compounder, weʼve seen significant increases in our cost efficiency and ability to stay competitive in the cutthroat market for polyamide compounds,” states Ye Yaoting at Zhejiang Xinli. The compounder is a twin-screw extruder of the new ZE Performance series from KraussMaffei Berstorff. Its performance profile is adapted precisely to the needs of the mid- to high-range market. On a total of 25 lines with a yearly capacity of 20,000 tons, Xinli produces flameproof and reinforced PA6 and PA66 compounds for the automotive and electrical industries. Customers in these industries have very high standards. High product quality is absolutely essential for any plastics processor that hopes to stand out from the competition and earn the business of customers like Chint, Tengen, Huanyu or Great Wall Motors. Ye Yaoting says, “Thanks to the excellent, gentle mixing of the new extruder, the compounds that it produces have significantly better mechanical properties than comparable products, and there is also greater machine productivity.”
Wide range of applications
Like all twin-screw extruders, the ZE Performance is equipped with process elements that were developed exclusively by KraussMaffei Berstorff using resources from renowned suppliers. In conjunction with the screw elements developed specially for the standard compounding tasks, the ZE Performance offers a wide application range for compound quality and productivity. The process unit has a modular design. This allows it to be adapted to various applications throughput quantities. ZE Performance machines are available in sizes 52 and 62 for throughputs of 300 to 1,200 kg/h. They cover the entire standard spectrum for compound manufacturing. Four housing sizes in various models with L/D ratios of 4, 8, 10 or 12 are available for optimum process adaptation. Cooling is by means of water injection, and heating by means of electric heating cartridges. The C-clamp flange system for quick and easy housing element replacement ensures short setup time. It is not only the performance parameters of the extruder that are “well known on the market and increase the trust of our customers in our products,” according to the satisfied Chinese customer. The experience of collaborating with the team from the machine manufacturer also won him over. He states, “KraussMaffei Berstorff has provided us with a tailored solution and supports us promptly and in a highly professional manner with all our questions and concerns.”
