Casting is the process of pouring molten metal liquid into the mold, cooling and solidifying to obtain the required shape and performance of parts. Casting is a commonly used manufacturing method with low manufacturing costs and high process flexibility, which can obtain complex shapes and large castings. It occupies a large proportion in mechanical manufacturing, such as machine tools accounting for 60-80%, automobiles accounting for 25%, and tractors accounting for 50-60%.
Due to the increasing requirements for casting quality, precision, cost, and automation, casting technology is developing towards precision, large-scale, high-quality, automation, and cleanliness. For example, in recent years, China has developed rapidly in precision casting technology, continuous casting technology, special casting technology, casting automation, and casting molding simulation technology.
