EVENT PREVIEW | CHINAPLAS 2018


Oriented approach KraussMaffei Berstorff is to introduce its biaxially oriented PVC (PVC-O) pipe technology at the show, in cooperation with local producer Baosu Pipe Industry, based in Hebei province. Since signing an agreement at the end of 2017, the two companies – which have worked together since the 1980s – have been pushing interna- tional sales of their PVC-O technology.


“Baosu is a specialist in


PVC pipe extrusion that has concentrated on the development of special stretching technology over many years,” said


Andreas Kessler, general sales manager at KraussMaffei Berstorff in Munich.


Among other developments, the company will contribute its twin-screw extruder for U-PVC production based on its latest technology.


“Baosu is planning to install a

system – equipped with our twin-screw extruder – for demonstration purposes,” said Kessler. PVC-O pipes can achieve nearly twice the


impact resistance of standard PVC pipes, as well as higher internal pressure resistance and a weight reduction of up to 40%, said Kessler. The pipes will mainly be used for wastewater and drinking water supply. Baosu will market the finished product under the brand name Taiji Blue pipe. KraussMaffei Berstorff will also showcase its QuickSwitch technology, which allows automatic in-line pipe dimension changes. “Our system for fully automated dimension

changes, tried and tested for years in day-to-day production, saves time and money and is a prime example of cost-effective production,” said Bengt Schmidt, vice president of plastic extrusion in China.


QuickSwitch allows producers to make small


order batches with short set-up times and minimal material waste, says the company. At the show, it will demonstrate a tapered piece


to illustrate the transition from the manufactured diameter into the new dimension (160 to 250mm).


Filter debut For the first time under the Maag umbrella, Ettlinger will present its ERF350 melt filter at Chinaplas.


40 PIPE & PROFILE EXTRUSION | April 2018 www.pipeandprofile.com


The device, introduced to the market in late


2017, filters plastic melts with impurities and separates foreign materials such as paper, alumini- um, wood, elastomers or plastics which fuse at a higher temperature with impurity levels up to 18% – all with very low melt losses. Designed for high efficiency, it achieves a maximum throughput of 3800kg/h, depending on the type of melt and degree of impurities, as well as the selected filtration rating. It is suitable for all commonly used polyolefins and polystyrenes as well as a large number of technical plastics such as styrene copolymers, TPE and TPU. Maag acquired Ettlinger at the start of this year, and sees two strong melt filtration players combine their operations. At the time, Ueli Thuerig, president of Maag, said: “Bundling our products and strengths will deliver a new breadth of custom solutions for plastic filtration.” In the near future, the combined companies will look to vertically integrate their portfolios – though will continue to operate under their existing brand names.


Maag has production sites in Switzerland,


Germany, the USA, Italy and China, while Ettlinger has a manufacturing site in Germany. Volker Neuber, CEO of Ettlinger, said: “This is a unique opportunity to expand our product portfo- lio and offer our customers complete solutions. At the same time, we are extending our geographic reach, so will be able to enhance our customer service on a global scale.”


Feeding time Coperion K-Tron will highlight a range of materials handling technologies at Chinaplas, including a quick-change feeder and a pump for conveying solid material. Its K2-ML-D5-T35/S60 Quick Change (QC) feeder features its ActiFlow bulk solids activator
