What is the process flow of stainless steel precision casting?

Stainless steel precision casting is to use a mold to pour molten metal into a prefabricated cavity, and then cool it to form the required parts or components. This process is particularly suitable for the production of stainless steel products with complex shapes and sizes. What is the process flow of stainless steel precision casting?

The process flow of stainless steel precision casting includes:

Mold making: Make a precise sand mold or metal mold according to the design drawings.

Melting metal: Put the selected stainless steel material into the furnace and heat it to liquid state.

Pouring: Pour the molten metal into the pre-prepared mold.

Cooling: Let the metal cool naturally in the mold or cool it by controlling the cooling rate.

Demolding: Remove the cooled casting from the mold.

Cleaning: Remove the gate, flash and other excess parts on the surface of the casting, and grind and polish it.

Heat treatment: The casting is subjected to heat treatment processes such as quenching and tempering as needed to improve its mechanical properties.

Surface treatment: Perform necessary surface treatments such as polishing, electroplating, sandblasting, etc. to improve appearance and corrosion resistance.

Quality inspection: Strict inspection of castings for size, appearance and performance to ensure compliance with design requirements and standards.

Because stainless steel precision casting can produce high-quality parts, it has been widely used in many manufacturing fields, such as aerospace, automobiles, medical devices, petrochemicals, etc.
