Meltblown Nonwoven Extrusion or Injection
The melt blown process is a nonwoven manufacturing system involving direct conversion of a polymer into continuous filaments, integrated with the conversion of the filaments into a random laid nonwoven fabric.
The melt blown process involves the attenuation of the filaments using high-velocity hot air streams that impinge on the extruded filaments as they are emerged from the extrusion nozzles to obtain much finer filaments.
Meltblown Nonwoven as the filter of the face masks, in recently because of the COVID-19 outbreak, the demand is increased so much. And the meltblown nonwoven extruder becomes the hot sale machine besides the face mask making machine. The screw and barrel size for SJ45 meltblown process extruder is available from RobotDigg.
