Casting is a kind of early metal hot working technology, which has a history of about 6000 years. In the middle of 1700-1000 B.C., China has entered the heyday of brass casting, its processing technology has reached a very high level. Casting is to cast the liquid metal into the casting cavity which is consistent with the appearance of the parts. The manufacturer of the low-pressure casting parts will get the parts the rough embryo after it is cooled coagulated. Most of the cast chemicals are solid but heated to liquid metals (such as copper, iron, aluminum, tin, lead, etc.), while the raw materials of the mold can be sand, metal even porcelain. Different regulations are applied in different ways.

Casting refers to the production processing method of melting solid metal into liquid pouring it into a special mold, manufacturing low-pressure aluminum castings in Zhejiang to be solidified. The cast metals include: copper, iron, aluminum, tin, lead, etc. generally, the raw materials of the mold are raw sand, clay, sodium silicate, epoxy resin other auxiliary materials. The special casting mold includes: investment casting, lost foam casting, metal casting, porcelain casting, etc. (the original sand includes quartz sand, magnesia, zircon sand, chromite sand, forsterite sand, sapphire sand, high-purity graphite sand, iron sand, etc.)
