Casting is one of the common production processes of the rough parts. Because casting can use cast aluminum alloy with various components and characteristics, and with the advantages of low investment in infrastructure projects, processing technology coordination ability and short production cycle time, it is widely used in mechanical equipment manufacturing, mining and metallurgical industry, road transportation, petrochemical general machinery, agricultural machinery. Energy power, light industrial textiles, electrical products, civil construction, power electronics technology, aerospace.

Energy power, light industrial textiles, electrical products, civil construction, power electronics technology, aerospace. Every field of social economy, such as national defense and military industry, is the basis of the production of modern large-scale machinery industry. Compared with other production and processing processes, the casting department is limited by the net weight, specification and appearance of the parts' gross embryo. The net weight ranges from multiple to hundreds of tons, and the wall thickness ranges from 0.3 mm to 1 mm, which is very complex. It is very difficult to manufacture by mechanical processing. It consumes a lot of construction time of CNC lathe, and even the parts that cannot be made can be obtained by casting.
Casting process (molding design, core making, pouring, sand dropping, cleaning and post-treatment process, etc.) is the key of casting production process, and is the key to the production and manufacturing of castings. Since ancient times, the improvement and development trend of technical level have been regarded as a key component to promote the technical development of the field and achieve economic development and social and economic development.
Scientific research on a series of structural mechanical, physical and organic chemical changes in the whole process of mold filling, crystallization, condensation and refrigeration, including the internal changes of castings, and the interaction between castings and molds, is very important for castings. It is the key technical basis for understanding the casting process design scheme, improving the casting process, avoiding the defects of castings, and improving the quality of castings.
