Shanghai Meihong Machinery Manufacturing Co., Ltd. have Powerful power casting parts,aluminum casting latest market quotes,aluminum casting the importance of,First-rate aluminum die casting,Good word of mouth casting parts,Top-notch aluminum die casting and other areas of expertise, combined with excellent service capabilities, To provide customers with professional, customized casting. Moreover, since the establishment of a long time ago,the castbusiness of Meihong Machinery has always maintained a high-speed and stable growth. details: There are many classification methods for castings: according to the different metal materials used, they are divided into steel castings, cast iron parts, cast copper parts, cast aluminum parts, cast magnesium parts, cast zinc parts, and cast titanium parts. Each type of casting can be further divided into different types according to its chemical composition or metallographic structure. For example, cast iron parts can be divided into gray iron castings, ductile iron castings, vermicular graphite iron castings, malleable iron castings, alloy cast iron fittings, etc.; according to different molding methods, castings can be divided into ordinary sand castings, metal castings, and die castings. , centrifugal castings, continuous castings, investment castings, ceramic castings, electroslag remelting castings, bimetal castings, etc. Among them, ordinary sand castings are the most widely used, accounting for about 80% of all castings. Non-ferrous metal castings such as aluminum, magnesium and zinc are mostly die casting parts.Theoretical metal liquid forming of castings is often referred to as casting, and casting forming technology has a long history. As early as 5,000 years ago, our ancestors were able to cast red and bronze products. Casting is the most widely used metal liquid forming process. It is a method of casting a liquid metal into a mold cavity and obtaining a shaped blank or part after it is cooled and solidified.The proportion of liquid molded parts in machinery and equipment is very large. In machine tools, internal combustion engines, mining machinery, heavy machinery, liquid molded parts account for 70%~90% of the total weight; in automobiles and tractors, 50%~70%; Agricultural machinery accounts for 40% to 70%. The liquid molding process can be used in such a wide range of applications because it has the following advantages: (1) It is possible to manufacture a blank having a complicated inner cavity and a complicated shape. Such as various cabinets, machine bed, cylinder block, cylinder head and so on. (2) The process flexibility is large and the adaptability is wide. The size of the liquid molded part is almost unlimited, and its weight may be from several grams to several hundred tons, and the wall thickness may be from about 0.5 mm to about 1 m. Any metal material that can be dissolved into a liquid state in the industry can be used for liquid molding. For cast iron with poor plasticity, liquid forming is the only way to produce its blanks or parts. (3) The cost of liquid molded parts is low. Liquid forming allows direct use of waste parts and chips, resulting in lower equipment costs. At the same time, the liquid molding parts have a small processing margin and save metal.
