Screen changer should be used in polymer extrusion system

　　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 defects of the quality of the production when it enters the subsequent extrusion die. In order to eliminate these effects and ensure that pure plastic melt enters the mould, it is necessary to add a melt screen-changing filter between the screw extruder and the mould to filter the impurities in the plastic melt, so as to effectively guarantee the quality of the final product.
  
The melt filter equipment provided by Zhengzhou Bart net changer manufacturer includes single board fast screen changer, cylindrical hydraulic screen changer, film blower automatic screen changer, etc.
