(Munich, June 15, 2016) The K 2016 trade show in Düsseldorf (October 19 to 26, 2016, Hall 15, booth B27/C24/C27/D24) will feature KraussMaffei Berstorff’s custom solution for 36D twin-screw extruders, which is designed for high-performance extrusion of U-PVC pipes with minimum space requirements. The combination of two KMD 108-36 E2/R twin-screw extruders produces at a throughput of up to 2000 kg/h, providing an impressive demonstration of intelligent and individualized systems engineering. The longtime success story of the 36D twin-screw series is due to the high overall system efficiency (OEE) with its process technology features that are designed to increase output. In this respect, with OEE Plus KraussMaffei Berstorff supplies its customers with premium quality solutions.

High-output production of PVC standard pipes in tight spaces
“We not only distinguish ourselves with our high level of expertise as a system provider, but also are in demand as a capable partner for customized systems engineering,” explains Peter Roos, President of the Extrusion Technology Segment and of the KraussMaffei Berstorff brand. Our featured product is an optimal implementation of our customers’ requirements for increased performance while simultaneously minimizing the space requirements,” says Roos. The combination of two KMD 108-36 E2/R twin-screw extruders is designed to reduce the space requirements by about one-third. This enables production at the highest output, even in the smallest spaces. “This system is of particular interest to processors who manufacture U-PVC standard pipes in large quantities and must place particular focus on cost-effectiveness. Higher output with a smaller footprint cuts production costs over the long term,” says Roos, describing the extruder combination. They also feature exceptional energy-saving benefits. The energy requirements are lower compared to a larger extruder that uses the twin-strand. The high-performance combination saves 0.02 kW per h/kg of material throughput compared to a KMD 164-32/R.
The featured product is part of an exemplary combination with the KM-RK 23-250 pipe head, a model from the newly designed pipe head generation designed for a very large diameter range with very high outputs. Due to its design features such as flow channel volume and mandrel ridges configured for optimum flow, the pipe head is ideally suited for high-performance extrusion with consistently high quality. 

Process technology concept for performance and flexibility 
The process concept of the 36D twin-screw extruder from KraussMaffei Berstorff stands for the highest output in conjunction with maximum product quality in PVC processing. The main focus is on the long, effective preheating length, which ensures a balanced combination of shearing energy and heating energy, optimal material processing and thus excellent melt homogeneity. In addition, it ensures low compression values in the area of the throttle zones. Optimal wear-resistance is guaranteed by the deep-nitrided barrels and the molybdenum welded layer on the screw threads. This makes it possible to process even higher-filled PVC compounds optimally.
