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.

在压力升高的同时，塑料一方面被外部加热，另一方面塑料本身在压缩、剪切、搅拌的运动过程中，由于内磨擦力也产生了大量的热，在外力和内力的联合作用下，塑料温度逐渐增高，其物理状态也经历了玻璃态--高弹态--粘流态的变化，一般地说来，在加料段中主要是玻璃态，在螺杆螺纹逐渐减少的中间部分压缩段中，物料主要处于高弹状态，同时也逐渐的熔融，而物料到压缩段后部和化段作用处于粘流态了，这时我们称塑料已完全塑化了，由螺杆推力作用将塑化的塑料定压定量的从机头中挤出。
