Alloy Steel Casting Processes

Investment Casting steel casting

Investment casting, also called precision casting or lost wax casting process, is a very precision casting process that produces complicated, high-quality parts with splendid surface finish. It covers creating a wax pattern and coating it with ceramic slurry. The ceramic shell is heated while the wax mold inside would be melted, leaving a hollow cavity. Molten alloy steel metal is poured into the cavity with intricate geometry accurately. The shell is then shattered to get the part. This method is used in industries such as food, petrochemical, power, aerospace, marine, and medicine.

Sand Casting steel casting

Sand casting is a casting technique that employs a combination of sand, clay, and water to make molds. The mold is formed by compacting the mixture around a metal pattern, which is subsequently removed to generate a cavity for casting. Molten alloy steel metal is poured into this cavity, and the mold enables the creation of intricate designs. Once solidified, the sand mold is broken to obtain the completed cast part. Sand casting is economical and adaptable, rendering it appropriate for parts in the automotive, machinery, and agriculture sectors.
