Casting technology is a casting method using raw sand with certain properties as the main molding material.
The technology and method of producing castings by applying relevant casting theory and systematic knowledge. Including casting process, casting system, feeding system, air outlet, chilling system, special casting process, etc.
The contents of casting process design include: the design of casting process drawing, the design of casting drawing, the design of mold assembly drawing and the production of process card.
Casting is an ancient manufacturing method, which can be traced back to 6000 years ago in China. With the development of industrial technology, the quality of large castings directly affects the quality of products. Therefore, casting plays an important role in machinery manufacturing. The development of casting technology is also very rapid. Especially at the end of the 19th century and the first half of the 20th century, many new casting methods appeared, such as low-pressure casting, ceramic casting, continuous casting and so on, which were improved and applied in the second half of the 20th century.
Casting is a manufacturing process in which molten metal liquid is poured into the mold and cooled and solidified to obtain the required shape and properties. Casting is a common manufacturing method with low manufacturing cost and great process flexibility. It can obtain complex shapes and large castings. It accounts for a large proportion in mechanical manufacturing, such as machine tools account for 60 ~ 80%, automobiles account for 25% and tractors account for 50 ~ 60%.
Due to the improvement of casting quality, casting precision, casting cost and casting automation, casting technology is developing towards precision, large-scale, high-quality, automation and cleaning. For example, China has developed rapidly in precision casting technology, continuous casting technology, special casting technology, casting automation and casting molding simulation technology in recent years.
