POF film blowing machine works

POF film blowing machine works: POF film blowing machine is mainly dry polyethylene particles are added to the hopper, by virtue of its own weight of particles from the hopper into the screw, when the particles are in contact with the screw rotating inclined facet be plastic and oblique ridge vertical surface to produce a thrust, which shares the thrust to promote plastic particles move forward in the process goes on, the collision will produce friction between the plastic and the screw and barrel of plastic particles and particles gradually being external heating barrel melting, filter impurities, and then after weathering cool.
