Reasons and value of extruder-mounted screen changers

1、Filtering impurities: In the production and storage process of plastics, rubber and other raw materials, it is inevitable that some impurities will be mixed in, such as metal particles, carbonized materials, wood chips and so on. The screen in the screen changer can effectively filter these impurities to ensure the purity of the extruded material, avoid impurities affecting the quality and performance of the product, and prevent surface defects, holes, breakage and other problems.

2, to protect downstream equipment: impurities, if not filtered, with the material into the downstream equipment, such as melt metering pumps, molds, etc., may cause wear and tear on these precision equipment, clogging and other damages, reducing the service life of the equipment and work efficiency. Filtering impurities through the screen changer can reduce the occurrence of equipment failure, reduce maintenance costs and downtime.

3, improve product quality and stability: continuous and stable production process is very important to ensure the consistency of product quality. Screen changer can be realized in the case of no downtime or short downtime to replace the screen, to avoid production interruptions and material waste due to the replacement of the screen, to maintain the continuity of the production process, so as to improve the stability of product quality.

4, to adapt to different production needs: in the production of different specifications, different quality requirements of the product, may need to use different mesh or type of screen. Screen changer makes it easier and faster to replace the screen, can flexibly adapt to different production needs, improve the flexibility and adaptability of production.

5, improve production efficiency: the design of modern screen changer is constantly optimized, the operation is more simple, the time to change the screen is greatly reduced. This means that in the production process, the screen can be replaced more quickly, reducing downtime, improving the productivity of the extruder and increasing production.
