The counter-parallel twin-screw extruder was upgraded from the original 18: 1 to the current 26: 1. For the great progress of screw design theory and screw manufacturing technology, higher requirements have been placed on the temperature balance control of the screw core. The increase of the length of the plasticizing section and the equidistant measuring section ensure the stable extrusion and full plasticization of the material and improve the quality of the product. The breakthrough of flat twin screw and double hole barrel processing methods has effectively made up for some shortcomings of large conical twin extruders
counter-parallel twin-screw extruder special for PVC material,for PVC powder,PVC granules all can working.or by mixed material.it is good for PVC plasticization.for PVC profiles by counter parallel twin screw is best choice.we have successful customer running this machine at Europe.
Through proessional and meticulous technical design and specially designed long-acting thrust bearings and high-torque gear reducers, the reliable life of the extruder is guaranteed. Flexible combination structure makes various users' requirements for extruder satisfied
