1.Liquid metal filling is stable and speed is controllable.Avoiding turbulence,impact,spatter.Reducing roll gas and oxidation.
2.Metal has good fluidity to help thin-walled parts forming a clear and smooth surface casting.
3.The liquid solidify under pressure,and the feeding effect is good.So the die casting structure is dense,and the mechanical properties are high.
4.Low pressure casting gating system is simple,don’t need set up the riser.So the process yield is high.Like the car engine and aluminum cylinder head,it has over 85% utilization rate.
5.Easy to implement mechanization and automation.
