The principle of this system is that we can calculate the leak ratio of the airproof gate through detecting the change ratio of press in the cavity of airproof gate.
其基本原理是利用计算机高速采集密封门的密封腔内压力的变化规律，据此计算出密封门的泄漏率。

Hot runner nozzle is the terminal of the hot runner system, which includes the heating, the end of the gate, which can transfer the molten material to the mold cavity or the additional cold runner.
热流道喷嘴是热流道系统的终端，它包括加热，浇口的末端，它将熔料输送到模具型腔或附加的冷流道。
