ZE Basic twin-screw extruders ensure reliable, high-quality and cost-effective compounding of standard plastics

(Hannover, Guangzhou, 18th May 2015) On the occasion of this year’s Chinaplas in Guangzhou, China (20th to 23rd May 2015, hall 5.1, stand J 41) KraussMaffei Berstorff will exhibit a ZE 52 Basic twin-screw extruder designed for high-performance and cost-effective compounding. Chinese plastics producers have been using the proven technology of the ZE Basic series with great success for a number of years already.

Suzhou Sunway increases productivity

“The general market development compels many Chinese compounding companies to invest in sophisticated technologies in order to keep up with competitors and to meet current requirements in terms of delivery time, prices and quality,” says Michael Hofhus, Sales and Service Manager of KraussMaffei Berstorff in China, to explain today’s market challenges.

This is why KraussMaffei Berstorff’s customer Suzhou Sunway Polymer Co. Ltd. – located in Suzhou with a headcount of 220 employees and an annual turnover of nearly 900 million RMB – opts for ZE Basic twin-screw extruders to enhance both productivity and flexibility and the level of innovation. The longstanding customer especially appreciates the solution packages offered by KraussMaffei Berstorff. Last year, Suzhou Sunway installed a ZE 52 Basic equipped with a side feeder. This means that the company currently operates a ZE 25 UTXi laboratory extruder and three ZE 52 Basic twin-screw extruders at its production facilities. At the end of April, the Chinese compounder placed an order for two additional ZE 52 Basic twin-screw extruders with KraussMaffei Berstorff.

“Using the ZE Basic extruders, we will further increase our product quality and process stability in the compounding of standard plastics in order to meet the ever more stringent requirements of our customers,” explains Ren Jun, General Manager of Suzhou Sunway.

ZE 52 Basic twin-screw extruder for a wide range of compounding applications

The ZE 52 Basic exhibited on the occasion of Chinaplas is equipped with a water-cooled drive unit for a maximum speed of 600 rpm and with a side feeder for the introduction of fillers. To ensure adequate and efficient wear protection for this type of process, housings made either of nitriding steel or induction hardened CrMo with an l/d ratio of 4, 8, 10, or 12 can be used. The C-clamp flange system substantially reduces housing assembly and disassembly times. Depending on the application, the KraussMaffei Berstorff ZE Basic series can be provided with different screw elements of complementary functionality that are tailored to specific requirements in compounding.
