The conical twin-screw extruder has the characteristics of uniform plasticizing and kneading, high output, stable quality, wide adaptability, long service life and direct molding of pvc. Equipped with the corresponding molding head die and auxiliary machine, various thermoplastics, especially the PVC powder, can be directly sent out to the city, pipe, sheet, film, and special plastic products. Plastic modification and powder granulation process.

The melt can be plasticized and extruded at a lower temperature. The barrel is equipped with a cast aluminum heater, which has high thermal efficiency, fast and uniform heating, and is equipped with a cooling fan. The specially designed transmission part is driven by a new variable frequency motor or Driven by DC motor, it runs smoothly, has large transmission torque and high efficiency. Conical twin-screw stable speed regulation, high precision and energy saving. The intelligent dual-display digital temperature controller has high control precision and small temperature fluctuation. It has overload protection and fault alarm, screw core oil circulation constant temperature, barrel oil cooling and other functions, and is equipped with vacuum exhaust pipe device and quantitative feeding device.
