Parallel Twin Screw Pelletizing Extrusion Line

The parallel twin screw extruder is composed of the following system parts:

• Feeding system: Including hopper, mixing motor and feeding motor.

  
  

• Heating system: It mainly uses heating rods and cylinders to heat materials efficiently and promote plasticization.

  
  

• Cooling system: The heat exchange system composed of heat conducting oil or water is used to reduce the heat of the fuselage, so as to effectively control the temperature of the cylinder.

  
  

• Hydraulic screen changing system: Use replaceable filter screen to intercept impurities, improve the plasticization degree, and ensure the uniformity and stability of the quality of the output materials.

  
  

• Vacuum system: Extract water and other low molecular volatile substances from the materials.

  
  

• Electric control system: Monitor and control relevant equipment of main and auxiliary material system.

  
  

• Screw and Barrel: The most important part of the extruder can be divided into conveying section, melting section (exhaust port), plasticizing section (vacuum port) and discharging section.The screw system mainly completes the plasticizing and conveying process of materials, which has a great impact on the performance and quality of the finished products. The screw parameter settings of equipment of different models and manufacturers are different, which requires special attention.

High Filler Pelletizing Extrusion Line Introduction

High filling process refers to filling a high proportion of inorganic powder into the matrix resin, so that the filler can be evenly dispersed. In the process of processing, the matrix resin must not be excessively sheared and broken, and good physical properties can be maintained; At the same time, the pelletizer should maintain high output and reduce wear and loss.

Introduction of Engineering Plastic Pelletizing Machine

Engineering plastic (ABS, PA, PC, PPS, POM, PETP, )have excellent comprehensive properties, such as high rigidity, high mechanical strength, good heat resistance and insulation. They can be used in harsh physical and chemical environments for a long time. The modification of engineering plastics requires high stability of parallel twin-screw extruders, mainly reflected in the accuracy of the metering system, the ability of the transmission box to withstand high speed and high torque, the wear-resistant life of the barrel screw and the pelletizer, and the high automation and data of the whole system. Key technologies are as follows:

• Automatic weighing system based on weight-loss scale measurement, meeting the fluctuation error of each component raw material ≤ 0.5%.

  
  

• High reliability transmission box, torque grade up to 13.5n. M / cm3, rotational speed up to 1200rpm, transmission efficiency higher than 96%, safety factor ≥ 1.25.

  
  

• Provide a variety of barrel, screw and mandrel material solutions to meet the needs of customers at different levels.

  
  

• Provide a variety of barrel heating solutions to meet different energy-saving efficiency and stability requirements.

  
  

• Provide advanced double-layer composite water channel barrel cooling scheme to ensure uniform temperature on the left and right sides of the barrel while cooling efficiently.

  
  

• The cutter system of the pelletizer is made of imported materials, wear-resistant and durable, with sound insulation design, which is convenient for cleaning.

  
  

• Based on PLC, IPC and the Internet, it can realize automatic control integration of equipment, massive data storage, interconnection and intercommunication of multiple equipment, and facilitate various levels of management, remote debugging and diagnosis.

Introduction of Color Masterbatch Pelletizing Machine

The masterbatch is mainly used for coloring polymers, and mainly classified as black masterbatch, white masterbatch, color masterbatch and liquid masterbatch. The twin screw extruder is widely used in the production of color masterbatch due to its easy operation, low energy consumption and simple color changing. Process routes typically include premixed and multi-feeding.

Our equipment widely uses small gap design in color masterbatch production industry to improve shear dispersion ability and ensure product quality. The production process of functional masterbatch is similar to that of Color Masterbatch, which can be used for multiple purposes.

Introduction of Thermoplastic Elastomers Pelletizing Machine

Thermoplastic elastomer (TPE) is a multifunctional material that exhibits rubber elasticity at normal temperature and can be plasticized at high temperature. It has both the elasticity of rubber and the melt fluidity and reusability of thermoplastic. It can not only replace general vulcanized rubber, but also some general resins. It can also be extruded like plastic to keep its rubber elasticity unchanged, which can

be used in automobile, electronics, engineering and medical, etc.
