The twin screw extruder is developed on the basis of the single-screw extruder. Due to its good feeding performance, mixing and plasticizing performance, extrusion stability and other characteristics, it has been widely used in the molding of various plastic extrusion products processing. It is a special equipment suitable for extrusion molding of PVC powder and PVC wood-plastic particles. Equipped with different molds and auxiliary machines, it can produce all kinds of PVC plastic pipes, profiles, plates, sheets, bars and granulation.

The main structure of the twin screw extruder consists of a transmission device, a feeding device, a barrel and a screw. The functions of each component are similar to those of a single screw extruder. There are two parallel screws in the extruder placed in the "∞" cross-section feedstock. According to the different rotation directions of the two screws, the twin-screw extruder is divided into two types: the same direction and the opposite direction. The two screws rotate in opposite directions when working. According to the shape of the two screws and the different angle of the combination, the twin-screw extruder is divided into a conical twin screw extruder and a parallel twin screw extruder. In addition, according to the structure, there are meshing and non-meshing.

Compared with the traditional extruder, the twin-screw extruder has been optimized in structure, and it is more convenient to open and close for maintenance, which is convenient for regular maintenance of the equipment and the disassembly and replacement of old parts. It will not be discovered when there is a problem with the extruded product, causing unnecessary waste. At the same time, it can also save production costs. The optimization of the structure has greatly improved the production efficiency. The development direction of mechanical equipment is for the purpose of high production capacity and low energy consumption. The twin-screw has the characteristics of high torque and high speed, and the output of production products is high. Good efficiency, more and more favored by the plastic extrusion market.

The twin-screw extruder produced by Kunshan Oneplus Machinery Co., Ltd. is exported to Southeast Asia, the Middle East, Africa, Europe and other countries and regions for its superior performance, excellent production efficiency, professional technical support, and high-quality after-sales service.
