[0002] The traditional plastic processing technology is to add dry plastic particles into the lower hopper, and the particles enter the screw from the hopper by their own weight. When the particles come into contact with the bevel of the thread, the rotating bevel surface generates a thrust perpendicular to the bevel surface on the plastic, pushing the plastic particles forward. During the pushing process, the plastic gradually melts due to the friction between the plastic and the screw, the plastic and the barrel, the collision and friction between the particles, and the external heating of the barrel. The molten plastic is filtered through the die head to remove impurities and comes out from the die head. It is cooled by the air ring and blown through the herringbone plate.
