Pipe extrusion lines: A success story for China - made in China Twin-strand technology – produced locally with German engineering – to reduce unit wage costs drop-off table. The C6 line control system ensures optimum monitoring and safe process control. Expansion of the market position thanks to the successful Performance Series “Economical production, high outputs and perfect end product quality have also long been standard requirements in the mechanical engineering and system construction industry in China,” emphasized Michael Hofhus, Vice President Extrusion at KraussMaffei Berstorff in China. “As a competent system supplier, we have been satisfying precisely these needs of our customers through our product portfolio in the Performance Series from our plant in Haiyan for several years. On a highly competitive local market processors focus on both quality and lower unit wage costs,” said Hofhus. The twinstrand line, which will produce PP-R pipes live from 12.00 to 13.30, will demonstrate very clearly how economical production functions in a confined space. “In the last few years we have placed complete lines up to a diameter of 1200 mm on the market. However, we are not only very successful as a system supplier for complete lines, but also in business with individual machines,” added Hofhus. “With our single-screw extruder model KME 6030 B/R from the Performance Series, we offer processors a suitable machine concept, especially in regard to locally used materials,” said Hofhus. The 30D Series, an extension of the single-screw series that has been used successfully for many years, is perfectly designed to process local PP-R material thanks to its revised screw concept. “The advantage here is the short processing unit which ensures optimum thermal and material melt homogeneity with high output, and therefore a final product of the highest possible quality. Another important criterion for Chinese producers who are increasingly setting themselves apart from competitors on the local market through highquality products,” said Hofhus. The exhibit in the 30D Series, which is produced at the production plant in Haiyan, is equipped with the new userfriendly C6 control system with its modern operating philosophy. The line will produce PP-R pipes with a diameter between 20 and 40 mm at a speed of up to 25 m/ min per strand and an axial distance of 450 mm. The core components of the line are the singlescrew extruder KME 75-30 B/R, two co-extruders KME 20-25 D/C for strip production and two pipe heads KM-RKW 32 from the locally produced Performance Series. The line is completed by other components ranging from a suction conveyor, a cooling zone, a saw and a haul-off through to a 7 TN MAY 2016
