Casting is a metal forming method that involves pouring molten metal into pre prepared mold cavities whose shape and structure are adapted to the required parts. After the metal cools and solidifies, it is taken out of the mold to obtain castings with a certain shape, size, and performance.
Casting is an ancient manufacturing method with a history of about 6000 years, widely used in fields such as mechanical manufacturing, automotive manufacturing, engineering machinery, aviation, aerospace, and high-speed rail.
The advantages of casting include the ability to achieve mass production, improve production efficiency, reduce costs, and the ability to produce parts of various shapes and structures to meet production needs under different demand conditions.
The strength, hardness, and corrosion resistance of castings are the same or similar to those of forging, malleable cast steel, and treatable steel processes, making them suitable for different usage environments.
