Working state of shotsleeve is analyzed, further more according to my own experience some new design methods are proposed.
分析了压室的工作状况，进而根据自己的经验提出几种新设计方法。

The air entrapment of the liquid metal flow in the shotsleeve during the slow shot phase is one of the factors resulting in this kind of defect.
气孔是压铸生产中的常见问题，导致这一缺陷的原因之一就是在慢压射过程中压室内的金属液流动卷入了气体。

The T-junction channel used for the electromagnetic transfer system was designed, then liquid metal flows from the channel to the shotsleeve was simulated with software FLOW-3D.
