Do you know what is casting forming technology?

Often referred to as liquid molding of metal casting manufacturers, casting forming technology has a long history. As early as 5000 years ago,Chinese ancestors were able to cast copper and bronze products. Casting is the most widely used metal liquid molding process. It is the liquid metal is poured into the mold cavity, let it cool down after solidification, access to certain parts of the shape of the rough or methods.

In machinery and cast steel products in the large proportion of liquid molding pieces, in machine tools, internal combustion engines, investment castings, heavy machinery parts of the total weight of the liquid molding for 70% to 90%; in automobiles, tractors accounted for 50% to 70%; in agricultural machinery accounted for 40% to 70%. Liquid molding process can be so widely used is because it has the following advantages:

(1) It can be manufactured lumen of the rough shape is very complicated. Such as various cabinet, machine bed, cylinder block, cylinder head and so on.

(2) Process flexibility, adaptability:Liquid molding parts virtually unlimited size, its weight by a few grams to several hundred tons, and its thickness can be 0.5mm to about 1m. Industry who can melt into liquid metal material can be used for liquid molding. The poor ductility of cast iron, liquid molding blanks or part of their production only way.

(3) Liquid molding parts cost.:Direct use of waste liquid molding parts and chips, equipment costs are lower. Meanwhile, the liquid molding pieces small allowance, save metals.

However, the metal forming process is more liquid, and difficult to precisely control, so the casting quality is not stable enough. Forgings with the same kind of material as compared to liquid molding because of loose tissue, coarse grains, the internal prone to shrinkage, shrinkage, porosity and other defects. The lower mechanical properties. In addition, labor-intensive, poor conditions.

With liquid molding of new technologies, new processes, new equipment, new materials continue to use, the liquid molded parts quality, dimensional accuracy, mechanical performance has been greatly improved, improved working conditions, in the end, so that the scope of application of liquid molding process more broad.
