When the resin flow in the mold, the screw speed control and filled with resin after the pressure (pressure protection) control.

当树脂在模具内流动时，则控制螺杆的移动速度并在填充树脂后用压力(保压力)进行控制。

Therefore, if molds were filled at atmospheric pressure, "shrinkage" would make the molding deviate from the SHAPE of the mold.

因此，如果在大气压下向模子充料，成型件会因“收缩”而与模子的形状形成偏差。

Injection speed may be too slow causing freezing before mold is filled.

即计量太小注射速度太小导致充填结束之前树脂凝固。
