The melt-blown fabric extruder adopts high-quality extruder reducer, which has stable quality and long life; high-quality inverter motor of the motor; electrical control system, which is equipped with a humanized operating system for the extruder according to the actual situation; the design of the single-screw extruder is simple . The number of extruders for each production line of the cast film extrusion unit depends on the number of layers and the requirements for the layer. There are also three extruders, the materials of the three layers are different, and three sets of five-layer cast film are configured. Extruders are also equipped with four extruders. Its unique properties are widely used in mask filter materials, thermal insulation filling materials, medical sanitary materials, wiping materials, etc.
