Non-ferrous foundry is the basic material for the development of the national economy. The vast majority of industries such as aviation, aerospace, automotive, mechanical processing and manufacturing, electric power, telecommunications, construction, and home appliances are based on non-ferrous metal materials. With the rapid advancement of modern engineering, agriculture and science and technology, the status of non-ferrous casting in human development is increasingly important. It is not only an important strategic material in the world, an important means of production, but also an important material for indispensable consumption data in human life.

In non-ferrous metals, non-ferrous metals such as copper, aluminum, magnesium, and zinc can be used for colored casting. Non-ferrous metal castings are widely used in machinery manufacturing, aviation, automotive, construction and other industries. The share of steel castings in the use of iron and steel materials is very small, and steel mills are mostly supplied in the form of steel. Most of the smelters and processing plants are located in one place. Non-ferrous metal castings account for a large proportion (sometimes nearly half) of the use of non-ferrous materials, resulting in a large and complex series of cast alloys. Therefore, non-ferrous metal smelters often supply metal ingots with a certain chemical composition. Subsequent processes prepare various types of alloys; smelters and processing plants are often divided.
