Double working position melt filter  Screen Changer for Plastic Extruder

Thsi kind of hydraulic screen changer is also called
plate type hydraulic screen changer for plastic extruder
slide plate type double working position screen changer
single plate hydraulic screen changer for plastic extrusion machine

Benefits of this kind of hydraulic screen changer
1)filter and dischanrge the impurities mixed in the polymer melt, improve the quality of final products
2)greatly improve the plasticizing and homogenization of the raw material
3)increase the out-put capacity
4) easy operation and  reduce the labor costs
