The plastic go down the hopper smoothly and is gripped by the thread of the screw. It is forced to go toward the direction of the gear end along with the rotation of the screw. A mechanical transferring process is formed. During the running of the plastic from the feed port to gear end, a high pressure is formed in the process of plastic curing due to the gradual decreasing of the thread depth and the resistance of filter gauze, splitter plate and gear end. The high pressure helps to press the raw material and improve its heat conductivity performance and the quick melting of the plastic, at the same time, the gradual increasing pressure can help the gas which is among material particles exhausted from the air holes.
