多余的锁模力，可能让模具无法“呼吸”或排气，周期超时等，对模具分模线的挤压。

Heaping on the clamp force, makes the mold harder to "breathe" or vent, and over time, can permanently hob closed the vents on the parting line.

它的吸气、压缩、排气三个连续过程是靠转子、星轮旋转时产生周期性的容积变化来实现的。

Its inspiration, compression, exhaust process is on three consecutive rotor, when rotating stars round of cyclical changes in volume achieved.
