Our vacuum tube Wrapper has its own characteristics, Diecasting, size and shape is very stable. Solid very conducive to the closure Poles casting.
我们的真空管包封有自己的特点，是成形模浇铸的，外形尺寸非常稳的，很利于固封极柱的浇铸。

The results showed that although the vacuum smelting has strongly degassing capacity, the degassing effects is relevant to the relative humidity of compressed air in low pressure diecasting.
结果表明，尽管真空精炼具有很强的除气能力，但低压铸造的除气效果与压缩空气的相对湿度有关。
