CO-EXTRUDER

1. The main machine is equipped with parallel twin screw extruder in the same direction, multi-stage exhaust, all raw materials are free from drying, reducing labor intensity; The plasticizing and mixing effect is better, and the crystal points on the surface of the sheet are less. 2. Melt metering control, closed loop with extruder, extrusion pressure more stable. 3. Equipped with precision five-roll calender drive, the sheet can be fully cooled under high yield extrusion. 4. The whole line adopts man-machine interface display, equipped with temperature module management, one-button speed up and other functions, more convenient operation. 5. The mould adopts on-line manual screw adjustment, which greatly saves the time of adjusting the width of sheet material and does not leak material. 6. The machine is equipped with lateral precision feeding device, which can produce different colors and properties of the sheet. 7. The net changer of the main extruder adopts the double column circular long-acting filter, the single net changing time can be extended to 50-100 hours. 8. Large winding diameter (up to 1500mm), equipped with frequency conversion drive, constant tension control, so that sheet winding more orderly. 9. The frame adopts low center of gravity structure and heavy steel material, which makes the machine more stable and the sheet extrusion more stable.
