Product Description

The conical twin-screw extruder has the characteristics of uniform plasticization and mixing, high output, stable quality, wide application range, long service life, and direct molding of PVC powder. Equipped with corresponding molding head molds and auxiliary machines, 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 [1].
The conical twin-screw extruder has stable performance and can make the melt plasticize and extrude well 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 frequency conversion motor or a direct-drive flow motor, which has stable operation, large transmission torque and high efficiency. It can achieve stepless and stable speed regulation with high precision and energy saving through imported frequency converter or DC speed regulator. Adopt intelligent dual-display digital temperature controller, with high control precision 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


Coupled 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 kinds of ordinary control and microcomputer control. There are two main driving modes: DC speed regulation and frequency conversion speed regulation for users to choose.


Features:

The soft plasticization concept has always been throughout the screw design, providing 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 formulations can produce high-quality UPVC pipes
High-efficiency 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 precise automatic temperature control system, precise and stable speed regulation system
