In the production process of stainless steel precision casting, sulfuric acid oxide film is an important factor affecting the purity and transparency of stainless steel precision casting oxide film. The porosity, purity, thickness, and sealing quality of stainless steel precision castings directly affect the mirror effect of the castings.

The stainless steel precision casting oxide film contains a lot of impurities, which will result in lower purity and decreased transparency. The impurities in the oxide film mainly come from the stainless steel castings themselves, as well as a portion from the oxidation tank liquid, so the content of alloy elements in the castings can be minimized as much as possible.

The basic equipment required for stainless steel precision casting process includes: precision casting waxing machine, ice water machine, and air conditioning; Soaking hopper, floating sand machine, air conditioning, dewaxing furnace, dehumidifier, dehumidifier, hopper, vertical hopper, and wax immersion can also choose mechanical arm and automatic centralized wax supply system;

Sintering furnace, high financing Zhou Bolu, shell machine; Post treatment - cutting machines, grinding machines, sandblasting machines, sand cleaning machines, heat treatment furnaces, punching machines; Repair - pneumatic grinding machines, argon welding machines, grinding machines; Quality Assurance - Spectrometers, Cubic Elements, etc. These are quite common, and if you need more advanced ones, you also need vacuum casting furnaces, vacuum heat treatment furnaces, or X-ray furnaces, etc.

The production of stainless steel castings is relatively stable, and the quality, variety, performance, as well as the proportion of alloy steel and special steel of cast steel castings continue to improve. By adopting various refining processes and techniques, the development of new cast steel materials can improve the strength, toughness, and special properties of cast steel.
