DESIGN BASICS 36D twin-screw extruders with an optimized screw concept for ultra-flexible processing The 36D twin-screw extruders with their HPG (High Performance Geometry) screw concept are ideal in every way for producing U-PVC and M-PVC pipe, foamcore PVC pipe and PVC-O pipe. High Performance Geometry (HPG) The HPG screw design incorporates an effective preheating length with an extended output and mixing zone. The whole length of 36 L/D can be used for processing the PVC compound. This results in significant benefits for processors. The long effective preheating zone means a high degree of...

CUTTING MATERIAL COSTS PVC foamcore pipe - produced on Raw material costs can account for up to 90% of the manufacturing cost of plastic pipe. Material costs can be slashed by producing PVC foamcore pipe on 36D twin-screw extruders combined with the foamcore pipeheads developed by KraussMaffei Berstorff. The 36D twin-screw extruders deliver premium product quality. They can be used as main extruders or as coextruders. Foaming the middle layer of the 3-layer pipe reduces its density to as low as 0.6 kilograms per cubic decimeter. This reduces the total density of the composite pipe by up to 30%...

DETAILED PRODUCT INFORMATION Our modular extruder concept - the recipe for success with cost-effective, customer- specific solutions Like all the extruders built by KraussMaffei Berstorff, the twin-screw extruders in the 36D series are engineered to an intelligent modular design. Starting with a universal machine frame and a standard barrel, KraussMaffei Berstorff can supply customized extruders closely matched to customer requirements. A closed-loop controlled metering unit with a conveying spiral ensures constant specific melt throughput, even with different formulations. The metering unit...

DETAILED PRODUCT INFORMATION Lower material consumption and constant product quality - with twin-screw extruders Big savings in pipe manufacturing costs through the use of fillers or by foaming the core layer cannot be allowed to impact on pipe quality. Special metering unit for high filler content In the fiercely competitive PVC pipe market, where producers are face constantly increasing pressure on prices, there is a strong trend towards taking filler content as high as possible. This is especially the case for waste water pipe, but also increasingly for pressure pipe. Producers not only need...

DETAILED PRODUCT INFORMATION monitoring systems in the industry Centralized control of the extrusion line Meeting tough specifications for product quality and output demands a stable, reliable production process.
