Research on the improvement of production process of twin-screw extruder

As a kind of high-efficiency and high-precision plastic processing equipment, twin-screw extruder has a wide range of applications in actual production. However, with the continuous improvement of market requirements on product quality and production efficiency, the traditional production process has been difficult to meet the demand. Therefore, it is especially necessary to improve the production process of twin-screw extruder.

In recent years, the improvement of the production process of twin-screw extruder mainly focuses on the following aspects:

First, the screw structure has been optimised. The traditional screw design often has problems such as uneven material mixing and poor plasticising effect. In order to solve these problems, the researchers have adjusted the screw geometry, pitch, depth of screw groove and other parameters to enhance the mixing effect and plasticising quality of the material. These improvements not only improved the uniformity and quality of the product, but also reduced energy consumption and production costs.

Secondly, the temperature control system of the extruder was upgraded. Temperature is one of the key factors affecting extruder productivity and product quality. The traditional temperature control system often has problems such as large temperature fluctuation and low control precision. In order to improve the stability and precision of temperature control, the researchers introduced advanced sensors and control systems to achieve real-time monitoring and precise control of the temperature of each section of the extruder. These improvements have greatly improved product quality and production efficiency.

In addition, the extruder's feeding system and die design were optimised. The traditional feeding system often suffers from uneven feeding and clogging, while the irrational design of the die leads to problems such as inaccurate product shape and unstable size. To solve these problems, the researchers adjusted the structure and parameters of the feeding system, while optimising the mould design and manufacturing process. These improvements not only improve the dimensional accuracy and shape stability of the products, but also increase the productivity and reliability of the extruder.

In summary, the improvement of the production process of the twin-screw extruder involves a number of aspects, including the optimisation of the screw structure, the upgrading of the temperature control system as well as the optimisation of the feeding system and die design. These improvements have not only improved product quality and production efficiency, but also reduced energy consumption and production costs. In the future, with the continuous progress of technology and market development, the production process of twin-screw extruders will continue to be improved and optimised, making greater contributions to the development of the plastics processing industry.
