High quality compounding twin screw extruder for plastic industry

Date:2022-3-24 Author:xinchen1

Twin-screw extruders is one kind of compound extruder which have screw threads made of high grade steel with a five-axis machining tool to reduce clearance and wear.

This twin screw extruder is equipped with PLC controllers and high-level touch screen panels for manual or automatic operations. The extruder’s operating parameters are input and displayed on the touch panel. Designed by CAD, the closely intermeshed screw elements have excellent self-wiping characteristics, and can be interchanged with each other easily. Besides, twin-screw compounding extruder is installed with the newly designed torque distribution system, high-precision grinding of hardened gear teeth, and imported high-quality key bearings.

Furthermore, the system is capable of remote control. This twin screw extruder can be extensively used in many fields, such as polymer blending, homogeneity, plasticization, filling modification and granulation, engineering polymer and glass fiber reinforcement, master batch, functional parent granule, special material, power coating material and cable material reactive extrusion, degassing and devolatilization, etc.

All twin-screw compounding extruders meet or exceed CE and international safety standards. The compound extruder can also designed by customers’ specifications.

Co-rotating twin-screw extruder : Due to the co-rotating twin-screw has the opposite speed at the meshing point, one screw pulls the material into the meshing gap, and the other screw pushes the material out of the gap, resulting in material from one screw turns to the other screw and advances in a “∞” shape. Since the gap of the meshing zone is small, the speed of the meshing screw and the groove are opposite in direction, so that the cutting speed is high, and the self-cleaning effect is good, that is, any accumulated material adhering to the screw can be scraped off, thereby The residence time of the material is very short, so the twin screw extruder is mainly used for compounding and pelletizing . This kind of compound extruder can greatly improve the pelletizing effect.

There is also one compund extruder which making masterbatches.AC cable
