Casting is a kind of hot metal processing technology which has been mastered by human beings for about 6000 years. China entered the heyday of bronze casting around 1700 ~ 1000 BC, and reached a high level in technology. Casting is a method in which liquid metal is poured into a casting cavity corresponding to the shape of the part, and after it is cooled and solidified, the part or blank is obtained. Most of the cast materials are metals (e.g., copper, iron, aluminum, tin, lead, etc.) that were once solid but heated to liquid state, while the casting materials can be sand, metal or even ceramics. Depending on the requirements, different methods will be used.

In the 20th century, the development of casting is very fast, one of the important factors is the progress of product technology, casting requires a variety of mechanical and physical properties are better, but still have good mechanical processing properties;Another reason is that the development of machinery industry and other industries such as chemical industry and instrument industry creates favorable material conditions for the foundry industry.For example, the development of detection means ensures the improvement and stability of casting quality and provides conditions for the development of casting theory.The invention of electron microscope helps people to go deep into the micro world of metal, explore the mystery of metal crystallization, study the theory of metal solidification, and guide casting production.
