Plastic conical twin-screw extruder is mainly used for extruding PVC and WPC materials. Coordinated with the appropriate auxiliary machinery, it can produce many kinds of plastic products, such as: PVC pipes, PVC profiles, PVC panels, WPC profiles, WPC boards/panels, pvc/wpc pelletes and so on.
Structural features of Plastic conical twin-screw extruder:
A1: Unique screw design, the material stays in the barrel for a short time, and the mixing and plasticizing effect is good;
A2: Using high-quality gearbox, beautiful appearance, stable operation and low noise;
A3: The barrel adopts copper fin ceramic heater and air cooling system, which has good heating and cooling effects and precise temperature control;
A4: The use of vacuum exhaust system can exhaust the moisture and volatile gases in the materials, which can improve the quality of products;
A5: The main motor adopts thyristor DC speed regulator or frequency conversion speed regulator, the output torque of the motor is stable, and stepless speed regulation can be realized.
A6: Vacuum shaping device: profile shaping table, all parts in contact with water are made of stainless steel.
A7: Traction machine: a series of two-track profile traction machine to meet the production requirements of different profiles.
A8: Cutting machine: blade-free cutting, sawing, planetary sawing (with chamfering).
A9: Stacking device: automatic turning or roller stacking device
