Why do polymer extrusion systems use mesh screen changers

Zhengzhou Batte Technology Co., Ltd. focuses on the research and development, production and sales of screen changers. It relies on strong technology accumulation and invention patents to occupy the technological highland in the network changer industry. It provides more than 2,000 customers with screen changer filtering solutions, which improves efficiency and saves costs. The reasons for the use of screen changers in polymer extrusion systems are described as follows:

In the process of polymer extrusion, the polymer melt will produce residue and some impurities in the raw material due to long time plasticization and heating, which will cause blockage of the runner and defect of the quality of production when it enters the subsequent extrusion die. In order to eliminate these effects and ensure that pure plastic melt enters the die, it is necessary to add a melt screen-changing filter between the screw extruder and the die to filter the impurities in the plastic melt and effectively guarantee the quality of the final product.
