摘　　要：它是通过对真空密封造型法、实型铸造和磁型铸造等新工艺进行"工艺嫁接"而产生的一种新的铸造方法。它省时、省力、减少清砂工时、提高产品质量、降低工时和材料费用、浇注后2 h,即可开箱清砂,装箱,进行再浇注,大大提高了劳动生产率。It is a new system technique of casting that including the vacuum sealed molding process, the full mould casting. It will use less time and fewer labors. It also can raise quality of our products while reduce the time of sand removal and the overhead of material. You can clean the trunk and refill the sand into it so that you can work again after tow hours you did last time. Extranets greatly increase the speed and efficiency with this new method.

关 键 词：负压 真空 表面质量 效率
