The theory of casting forming metal liquid forming is often called casting, and casting forming technology has a long history. As early as 5000 years ago, our ancestors were able to cast red copper and bronze products. Casting is a widely used liquid metal forming process. It is a method of pouring liquid metal into the mold cavity and obtaining a blank or part of a certain shape after it is cooled and solidified.

The proportion of liquid molding parts in machinery and equipment is very large, and the liquid molding parts account for 70% ~ 90% of the total weight in machine tools, ship inspection castings, internal combustion engines, mining machinery and heavy machinery; Accounting for 50% ~ 70% of automobiles and tractors; Accounting for 40% ~ 70% of agricultural machinery. The liquid forming process can be widely used because it has the following advantages:

(1) It can produce the blank with complicated inner cavity and shape. Such as various boxes, machine bed, cylinder block, cylinder head, etc.

(2) The process is flexible and adaptable. The size of the liquid shaped part is almost unlimited, its weight can be from a few grams to several hundred tons, and its wall thickness can be from 0.5mm to about 1m. In industry, all metal materials that can be dissolved into liquid state can be used for liquid forming. For cast iron with poor plasticity, liquid forming is the method to produce its blanks or parts.

(3) The cost of liquid molded parts is low. Liquid molding can directly use waste parts and chips, and the equipment cost is low. At the same time, the machining allowance of the liquid shaped parts is small and the metal is saved.
