Stainless Steel Investment Casting
Stainless steel investment precision casting:
The investment casting precision casting process, in simple terms, is to use fusible materials (such as wax or plastic) to make a fusible model (referred to as investment mold or model), coat it with several layers of specially made refractory coating, dry it to form a whole shell, then melt the model from the shell with steam, and then put the mold into a high-temperature roasting furnace for high-temperature roasting. After roasting, the mold or shell is poured with molten metal to obtain the casting.
