Conical Twin Screw Plastic Extruder

This SJSZ conical twin screw plastic extruder is the specialized equipment suiting for extrusion shaping of diversified PVC powder materials. With different molds and auxiliary machines provided, it is able to manufacture all kinds of PVC plastic pipes, profiles, panels, sheets, bars and plastic granules. Moreover, this product can adapt to the high speed extrusion of PP and PE pipe products under the help of its dedicated barrel and screw.

The control system of our conical twin screw plastic extruder allows to be operated by special computer or general control. In respect of different requirements on configurations of customers, it is structured with the most proper screw to get optimum plasticizing and flowing state of the materials. All the screws are processed by specialized numerically controlled milling machine precisely so as to keep the consistent extruding performance of each machine in the same type.

We are the first to apply the international most advanced technology of changing the pitch and depth of the screw in China. Then the flowing materials will be sheared and compressed more moderately while passing the screw, approaching the actual needs of customers more effectively. Meanwhile, this conical twin screw plastic extruder uses the distribution case in particular design. Its enlarged thrust bearing is imported, bearing larger extrusion pressure with long working life.
