介绍了一种在压力下真空密封铸造的新方法简称ＰＶ法，试验结果表明，与Ｖ法铸造相比，金属液在压力下真空密封铸造中有更好的充型能力。用ＰＶ法可以铸造出黑色金属薄壁铸件。
A new method of vacuum-sealed casting under pressure, referred to as PV method, is introduced. The experimental results show that the molten metal has better filling ability in vacuum sealing and casting compared with V method. P V method can be used to cast black metal thin-walled castings.
