Single screw plastic extruder production line
Working principle
The polypropylene raw material is put into the extruder, after melting between the screw and the barrel, it is transported to the melt pump and the filter, after filtering, it is quantitatively sent to the spinneret assembly. At this time, the hot air flow on both sides of the spinneret hole blows out the melt material at a speed close to the speed of sound, so that it is quickly thinned, and in the falling process, it is cooled and solidified by the traction air flow on both sides.
