Casting a variety of classification methods: by its use of different metal materials into steel, cast iron, bronze pieces, cast aluminum, cast magnesium parts, pieces of cast zinc, cast titanium parts. And each class can be divided according to their chemical composition or casting microstructure further divided into different categories. Such as cast iron can be divided into gray iron castings, ductile iron castings, vermicular cast iron, malleable iron, alloy cast iron pieces; according to different methods for molding, casting can be divided into ordinary sand casting, metal casting, die casting centrifugal casting, continuous casting parts, castings, ceramic castings, castings ESR, bi-metal castings. Which the largest port sill guard round supply of ordinary sand casting applications, accounting for about 80% of the total cast production. The aluminum, magnesium, zinc and other nonferrous castings, mostly casting. Casting historic application. Ancient people used to make castings and some life appliances. Modern ports wheel guard ridge, casting machine is mainly used for rough parts, some precision castings can also be used directly as machine parts. Casting mechanical products occupy a large proportion, such as tractors, the casting weight of about 50 to 70% by weight of the machine, agricultural machinery accounted for 40 to 70 percent, machine tools, internal combustion engines, such as the 70 to 90%. All kinds of castings, castings varieties most port machinery wheel guard Hom products, the most complex shapes, the amount is also the largest, accounting for about 60% of total production of castings. Followed by the ingot mold and metallurgical engineering pipeline, as well as some of the tools of life. Casting metal forming theory often called liquid molding casting, casting forming technology has a long history. As early as 5000 years ago, our ancestors will be able to cast copper and bronze. Casting is the most widely used metal liquid molding processes. It is the liquid metal is poured into the mold cavity, wait until the cooling and solidification, to obtain a certain shape or parts of the method blank. Casting very versatile, has been applied to the metal and the whole machinery and electronics industries, and its use is a growing trend. Specific use, construction, hardware, equipment, construction machinery and other large machinery, machine tools, shipbuilding, aerospace, automotive wheel guard Hom harbor price, locomotives, electronics, computers, appliances, lighting and other industries, many of which are ordinary people all day contact but do not understand metal objects.
