Double Plate Type Hydraulic Screen Changer for Plastic extruder

Double plate screen changer play an important role in industrial production, especially in the field of polymer material processing, such as plastics, rubber, and other industries. As an advanced mesh swapping equipment, dual board mesh swappers have significant advantages in improving production efficiency, ensuring product quality, and saving energy. This article will provide a detailed introduction to the structure, working principle, application areas, and maintenance of the dual board screen changer, helping readers better understand and apply this technology.

1、 The structure and working principle of a dual board screen changer

The dual plate screen changer mainly consists of two parallel arranged metal plates, heating elements, control system, etc. During the work process, one metal plate serves as a hot plate and the other as a cold plate. By adjusting the heating elements through the control system, the hot plate reaches the set temperature, while the cold plate maintains a lower temperature through natural heat dissipation or external cooling equipment. When the polymer material flows through a hot plate, it softens upon heating and then enters the narrow gap between two metal plates. Through compression and shear, the material undergoes a mesh exchange process.

2、 Application fields of double plate hydraulic screen changer

The double plate screen changer is widely used in the processing industry of polymer materials such as plastics and rubber. In the production processes of plastic extrusion, injection molding, blow molding, etc., the double plate screen changer can be used to filter impurities, change colors, switch grades, etc., thereby improving product quality and production efficiency. In addition, the double plate screen changer can also be used for vulcanization, rolling and other processes of rubber products, achieving rapid material screen changing.
