Extruder SJ45, SJ50, SJ65, SJ90 Extrusion Screw, and Barrel
The melt-blown process is a nonwoven manufacturing system involving the direct conversion of a polymer into continuous filaments, integrated with the conversion of the filaments into a randomly 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 filters for face masks, recently because of the COVID-19 outbreak, the demand is increased so much. And the melt-blown nonwoven extruder becomes the hot sale machine beside the face mask-making machine. The screw and barrel size for the SJ45 meltblown process extruder is available from RobotDigg.
Meltblown Process Extruder Screw and Barrel
Why RobotDigg are slow in the supply of desktop extruders, filament production lines, and pelletizing lines?
That is caused by the production of Meltblown Nonwoven Extrusion or Injection Machine SJ45, SJ50, SJ65 and SJ90 :-( This is because the price of the meltblown nonwoven extrusion machine is Big money, we call it Pandemic Economy Phenomenon.
The good news is that the Screw and Barrel for the larger extrusion machine SJ45, SJ50, SJ65, and SJ90 are dropping back to normal.
