The structure of the engineering plastic twin screw extruder barrel is basically similar to that of the single-screw extruder screw barrel. From the appearance structure, the twin-screw extruder barrel is also divided into an integral barrel and a segmented barrel. The engineering plastic twin screw extruder is an upgrade of the single screw extruder, which has also greatly improved the efficiency of use.

What are the reasons why people choose engineering plastic twin screw extruder?

1. Improve labor efficiency

When the equipment is repaired, engineering plastic twin screw extruder only needs to loosen a few bolts, turn the worm gear box handle device to lift the upper part of the barrel to open the entire barrel, and then perform repairs. This not only shortens the maintenance time, but also reduces the labor intensity.


2. High torque and high speed

The development trend of engineering plastic twin screw extruder in the world is towards high torque, high speed, and low energy consumption. The effect of high speed is high productivity. engineering plastic twin screw extruder belongs to this category, and its speed can reach 500 rpm. Therefore, it has unique advantages in processing high-viscosity, heat-sensitive materials.


3. Wide range of applications

engineering plastic twin screw extruder has a wide range of applications and can be applied to the processing of a variety of materials

4. High output, high quality

engineering plastic twin screw extruder has other advantages of ordinary extruder, and can achieve high output, high quality and high efficiency.


What is the workflow of engineering plastic twin screw extruder?

The engineering plastic twin screw extruder used for profile extrusion is usually tightly meshed and rotated in different directions, although a few also use co-rotating twin screw extruders, generally operating at a relatively low screw speed, about 10 r/ min. The high-speed meshing co-rotating engineering plastic twin screw extruder is used for compounding, venting or as a continuous chemical reactor. The maximum screw speed of this type of extruder is 300-600r/min. Non-intermeshing extruder is used for mixing, venting and chemical reaction. Its conveying mechanism is quite different from intermeshing extruder, which is closer to the conveying mechanism of single screw extruder, although there are essential differences between the two.


What are the essential devices in the engineering plastic twin screw extruder?

Among the straightening devices used in engineering plastic twin screw extruder, the most common one is eccentric, and various types of bending of the core are one of the important reasons for the insulation eccentricity. In sheath extrusion, scratches on the sheath surface are often caused by the bending of the cable core. Therefore, the straightening device in various engineering plastic twin screw extruder is indispensable. The main types of straightening devices are: drum type (divided into horizontal and vertical); pulley type (divided into single pulley and pulley block); winch type, which has multiple functions such as dragging, straightening, and tension stabilization; Press wheel type (divided into horizontal type and vertical type), etc.


The engineering plastic twin screw extruders are used more and more widely in daily life, but its quality has a great influence on the experience of use. Nanjing JlEYA has focused on the production and development of engineering plastic twin screw extruders for more than several years, and they have always put the needs of customers as their top priority.
