Counter-rotating twin-screw extruders for processing compounds
Counter-rotating twin-screw extruders are used throughout the world to process natural fiber-reinforced plastics such as wood plastic composites. The KraussMaffei Berstorff extruders of the 32D series feature a large number of advantages, for example constant material feed, careful material preparation and high pressure stability of the screws when manufacturing semi-finished products. They are also ideally suited for processing of a prepared compound. High screw torque – coupled with a long processing unit – produces the highest possible output rates. In addition to careful material preparation, the special screw geometry produces a homogeneous melt with an optimum melt temperature even with high melt pressures.
KraussMaffei Berstorff ensures maximum wear resistance through a special process concept, tungsten carbide protection of the screws, and bi-metallic lining of the barrel bores. The machines require very little maintenance and have a long service life.
