The lightweight casting has been prototyped by forming a foam structure in the casting using new method. In this study, molten metal is impregnated into a mold was filled small-diameter hollow iron ball of thin-walled (diameter 2-4 mm) in vacuum atmosphere. In the case of using a magnesium alloy, aluminum alloy and copper alloy as a metal to be impregnated, the lowest density ratio is 27%, 52% and 42%, respectively. Similar to the foam metal of conventional, large plastic deformation is obtained at a low stress in any case.

使用新方法在铸造中形成泡沫结构，已将轻量级铸件原型化。在这项研究中，将熔融金属浸入霉菌中被填充在真空气氛中的薄壁（直径为2-4毫米）的小直径空心铁球。在使用镁合金，铝合金和铜合金作为浸渍的金属的情况下，最低的密度比分别为27％，52％和42％。与常规的泡沫金属相似，在任何情况下，在低应力下都获得了大型塑性变形。
