Extruder ZSE Maxx Series
Extruders from Leistritz Extrusionstechnik GmbH, Nuremberg, Germany, are used in the production of BOPP (bi-oriented polypropylene) films. Now, a ZSE 135 Maxx extruder has been delivered to the Austrian-French company DMT. DMT is a supplier of machines and equipment for producing biaxially stretched plastic films, which, among other applications, are used as packaging materials in the food industry. The ZSE 135 Maxx has a screw diameter of 140 mm and enables extremely high torques together with a large free screw volume. DMT employs the extruder as part of a direct extrusion line. A total of 16 machines from Leistritz, with screw diameters of 75 to 140 mm, are now in operation at DMT.
Leistritz is also continuing to develop its program of large machines. Because of the success of the ZSE Maxx Series, it plans to deliver the first ZSE 180 Maxx in 2009. The twin-screw extruder is characterized by a greater flight depth of the screw elements, achieving a larger free volume together with high torque. The ratio of exterior to interior diameter has been increased from 1.5 to 1.66 in the ZSE Maxx series. A high-end gearbox has been able to significantly increase the specific torque.
