Abstract: | This paper briefly presents characteristics, application and development of the metallic foams. Sound specimen has been achieved with preparing foam aluminum by using investment casting process. The preparation of plaster prefabricated mould is one key in investment casting. Main composition, ingredient and affecting factors of plaster mould are also discussed and the vacuum-infiltrated shaping technique was found to be another important link. The penetrating model and the affecting mechanism of the main parameters were also analyzed. As a result, the optimum values were determined. |
