Extruder matching screen changer: double guarantee of quality and efficiency

Extruder supporting screen changer can improve product quality and production efficiency through the following ways:

I. Enhance product quality

Filtering impurities: In the extrusion production of plastics, rubber, ceramics and other materials, the raw materials may contain unplasticized particles, foreign objects and impurities mixed in the transportation or production process. The filter of the screen changer can effectively intercept these impurities and prevent them from entering the extrusion mold, avoiding defects such as flaws and bubbles on the surface of the product, and air holes and cracks internally, ensuring the surface quality and internal performance of the product.

Improve plasticizing and homogenizing effect: Adding the screen changer is equivalent to increasing the length of the melt runner, so that the melt is subjected to more shear and stirring effect during the extrusion process, thus improving the plasticizing and homogenizing effect of raw materials, and making the product texture more uniform, more stable performance and better finish.

Extend the life of the mold: the screen changer can reduce the wear and clogging of impurities on the mold, so that the working condition of the mold is more stable, thus prolonging the life of the mold, but also help to ensure the stability of product quality, reduce the incidence of product quality problems caused by mold damage.

2.Improve production efficiency

No downtime to change the screen: many modern screen changers with no downtime to change the screen function, such as single-plate duplex, double column duplex, mesh belt type automatic screen changer and so on. In the process of replacing the screen, the production line can maintain continuous operation without interrupting the production process, greatly reducing the production interruption time due to downtime to change the screen, improve the utilization rate of the equipment and production efficiency, but also reduces the frequent starting and stopping the equipment and the production of scrap.

High degree of automation: The extruder screen changer provided by Zhengzhou Batte can be equipped with advanced automation control system, which can automatically detect the clogging condition of the screen, and when the preset clogging degree or time is reached, it automatically triggers the screen changing program without frequent manual checking and intervention, realizing the functions of automatic screen changing and automatic cleaning etc., reducing the operation difficulty and error, and improving the automation level and efficiency of the production.

Optimization of runner design: High-quality screen changer can ensure smooth material flow, reduce pressure loss and temperature fluctuation by optimizing the runner design, such as adopting straight-through runner, so that the material can maintain a good flow state during the process of screen changing, which is conducive to improving the production speed and efficiency.
