Detail
Casting is the process of melting metal into a liquid that meets certain requirements and pouring into a mold, and obtaining castings with a predetermined shape, size and performance after cooling, solidification, and cleaning treatment. Casting blanks are almost formed, and the purpose of machining without machining or small amount of processing is reduced, and the production time is reduced to a certain extent. Casting is one of the basic processes of the modern device manufacturing industry. There are mainly two categories: sand casting and special casting. Casting molds are made from metals with higher melting points than raw materials. Among them, it is subdivided into gravity casting method, low pressure casting method and high pressure casting method.
