The conical twin-screw extruder is a highly efficient mixing and extrusion equipment. The machine has the characteristics of low shear rate, difficult material decomposition, uniform plasticizing and mixing, stable quality, high output, wide application range, and long service life.

Conical twin-screw extruder

Equipped with various specifications of molds and auxiliary machine production lines produced by our company, PVC powder can be directly made into plastic products with different cross-sections such as pipes, plates, and profiles. The electrical control system of the conical twin-screw plastic extruder is equipped with two types: ordinary control and microcomputer control. There are two main drive modes: DC speed regulation and frequency conversion speed regulation for users to choose.

Main features

The gentle plasticizing concept is always present in the screw design, which provides a strong guarantee for the high-speed extrusion of UPVC pipes

The reliable two-stage screw core external circulation temperature control system ensures that different formulas can produce high-quality UPVC pipes

The efficient and low-noise air cooling system, reliable and effective vacuum exhaust system, high-precision, wide speed regulation, forced quantitative feeding system, high-performance deceleration torque distribution gearbox, perfect and accurate temperature automatic control system, accurate and stable speed regulation system

Functions and uses

The conical twin-screw extruder has the characteristics of uniform plasticizing and mixing, high output, stable quality, wide adaptability, long service life, and direct molding of PVC powder. With the corresponding molding head mold and auxiliary machine, various thermoplastic plastics, especially rigid polyvinyl chloride powder, can be directly extruded into plastic products such as tubes, plates, sheets, rods, films and profiles, and can also complete the modification of various plastics and the granulation process of powder.

The conical twin-screw extruder has stable performance and can plasticize and extrude the melt 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 adopts a new variable frequency motor drive or a direct drive flow motor, which has stable operation, large transmission torque and high efficiency. The imported frequency converter or DC speed regulator can achieve stepless and stable speed regulation with high precision and energy saving. The intelligent dual-display digital temperature controller is adopted, which has high control accuracy and small temperature fluctuation. It is equipped with overload protection and fault alarm, screw core oil circulation constant temperature, barrel oil cooling and other functions, and is equipped with a vacuum exhaust pipe device and a quantitative feeding device
