消失模铸造（实型铸造）工艺近年来在我国推广和发展得比较快，它以其造型时无需起模，简化了铸造工艺、不用混砂、容易落砂、不用旧砂再生和旧砂回用率可达95％以上等优点，．IJM越来越受到许多铸造企业的重视。中、小铸造企业采用消失模铸造工艺生产铸件零活、工艺装备毛坯和 Lost foam casting (real casting) process in China in recent years to promote and develop relatively fast, it does not need to take the mold in its modeling, simplifying the casting process, no sand, easy to shake off the sand without sand regeneration and the old sand back Use up to 95% or more advantages. IJM more and more attention by many foundries. Medium and small casting enterprises using the lost foam casting technology to produce castings spare parts, process equipment and rough
