Process-Constant & Back-flushing Filter Screen Mesh

Extruder screen, also called filter screen, extruder screen pack, filter screen mesh, is used to filter impurities when melting plastic products. To make sure filtration fineness, back-flushing technique is adopted while producing the wire mesh filter screen and at the same time, we can provide filter screen mesh with different layers. The filter screens with multiple layers are so solid that they can be used several times during filtering rubber and plastic products.
