Casting has a history of about 6000 years. Casting refers to the process of melting solid metal into a liquid state, pouring it into a mold of a specific shape, and finally waiting for it to solidify. The metals to be cast are: iron, copper, tin, aluminum, lead, etc. Commonly used casting materials are raw sand, clay, water glass, resin and other materials. Special casting molds include: investment casting, lost foam casting, metal mold casting, ceramic mold casting, etc. Raw sand includes: quartz sand, magnesia sand, zircon sand, chromite sand, forsterite sand, kyanite sand, graphite sand, etc.

In the 20th century, the development of casting is very fast. One of the important factors is the progress of product technology, which requires castings to have better mechanical and physical properties, while still having good machinability. Another reason is that the development of the machinery industry itself and other industries such as chemical industry, instrumentation, etc. has created favorable material conditions for the foundry industry and ensured the improvement and stability of the quality of castings.
