Precision castings refer to castings with precise dimensions obtained through precision casting. Precision casting parts are precise and complex, close to the final use shape of the parts, and can be used directly without processing or very little processing. This is an advanced near-net-shape casting process.

Among them, precision steel castings are parts made of cast steel. There are many types of precision steel castings and they are widely used.

Applied to power station equipment. Power plant equipment is a high-tech product, and its main components can operate continuously for a long time under high load. Many parts of thermal power plants need to withstand the corrosion of high temperature and high pressure steam, so the reliability of the parts has very strict requirements. Steel castings can meet these requirements to a greater extent.

Railway rolling stock. Railway transportation is closely related to the safety of people's lives and property, and ensuring safety is very important. Some key components of rolling stock, such as wheels, side frames, bolsters, couplings, etc., are all cast steel parts used.

Construction, construction machinery and other vehicles. The working conditions of construction machinery and construction machinery are relatively poor. Most of the parts are subject to high loads or need to withstand impact and wear. Most of them are steel castings, such as drive wheels, load-bearing wheels, and rocker arms and track shoes in the mobile system. .
