| Abstract: | The quality of lost wax precision castings is closely related to shells. It is necessary for investment casting companies to un?derstand the influence of shell-making materials and process employed on the quality of shells. By using the shell-making process which has been tested maturly and stably in our company and choosing silica sol as binder, the performance of shells made of several Al-Si refractory materials is studied and the applicability of various shells is clarified in this paper. |
