In this paper, the integration technique about the combination of sintering alkali-corrosion resisting valve prototypes of PS-base powder material by SLS technique and manufacturing the valve castings by investment casting technique is introduced. Some problems about manufacturing of casting mold shell, especially in the disposal of wax patterns, are researched. On the grounds of all above, the rapid casting process from three-dimensional digital model to metal parts is drawn up.
