In the process of processing the processing materials of stainless steel precision castings, it is necessary to remove impurities such as dirt and oil. The reheating material of the product must effectively spray off its sand and oxide scale, and then it can be put into the furnace for smelting after being cleaned. After the bath is completely melted, low-carbon ferromanganese and low-carbon ferrosilicon are added as required for alloying and pre-deoxidation.

Dry sand casting differs from its green counterpart primarily in its use of dried molding sand. The molds are baked in an oven to harden the sand, creating a more rigid mold. This method reduces the moisture content and, in turn, the likelihood of defects like gas porosity.
