SJ80 Twin Screw Extruder 75-250mm PVC Pipe Extrusion Line with PLC control

Conical twin-screw extruder is an efficient mixing and extrusion equipment. The machine has the characteristics of small shear rate, difficult material decomposition, uniform plasticization and mixing, stable quality, high output, wide application range and long service life. With the various specifications of the mold and auxiliary machine production line produced by the company, PVC powder can be directly made into plastic products of different cross sections such as pipes, plates and profiles.

main feature:

The soft plasticization concept is always in the screw design, which provides a strong guarantee for the high-speed extrusion of UPVC pipes.

Reliable two-stage screw core external circulation temperature control system ensures high quality UPVC pipe production with different formulations

High-efficiency, low-noise air-cooling system Reliable and effective vacuum exhaust system, high precision, wide speed regulation, forced dosing system, high-performance deceleration torque distribution gearbox, perfect precise temperature automatic control system, precise and stable speed control system

Function and use:

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 powder. With the corresponding molding head die and auxiliary machine, various thermoplastics, especially hard polyvinyl chloride powder, can be directly extruded into plastic products such as tubes, plates, sheets, rods, films and profiles, and can also be completed. Modification of various plastics and powder granulation process.

The conical twin-screw extruder has stable performance, which can make the melt plasticize and extrude 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 DC motor, which has stable operation, large transmission torque and high efficiency. Through the imported inverter or DC converter, it can achieve stepless and smooth speed regulation, high precision and energy saving. The intelligent dual-display digital temperature controller has high control precision and small temperature fluctuation. With overload protection and fault alarm, screw core oil circulation constant temperature, barrel oil cooling and other functions, and equipped with vacuum exhaust pipe device and quantitative feeding device
