PLASTIC EXTRUSION SCREEN CHANGER
The plastic extruder screen changer is a crucial component used to filter impurities from raw materials during the extrusion process. This essential plastic extrusion screen changer ensures that contaminants are effectively removed, resulting in a higher quality end product. A screen changer for extruder systems, particularly the hydraulic screen changer, offers seamless and efficient operation, allowing for continuous production without the need for frequent shutdowns. By incorporating a reliable screen changer, manufacturers can maintain optimal performance and product consistency in their extrusion processes.
The filter screen is one of the indispensable parts of the film blowing machine, and its main function is to filter the impurities in the plastic raw materials, such as dust, not melted completely plastic particles, etc., and to avoid these impurities causing slippage or irreversible damage in the die head. The function of the filter screen in addition to filtering the impurities in the plastic raw materials, can also increase the friction resistance between the screw and the plastic raw materials in the extruder, and increase the back pressure at the same time to help achieve the complete mixing of raw materials.
