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。
When the resin flow in the mold, the screw speed control and filled with resin after the pressure (pressure protection) control.
采用金属型立式浇铸，严格控制铸造工艺参数(模具温度、浇注温度、浇注速度)，以避免气孔、缩松、冷隔等缺陷的产生。
By using metal mold casting, we can control mold temperature, infusing temperature, infusing speed to avoid defects of pore, cold partition, shrink and loose.
