What is called casting?
Casting (casting)
The casting is will metal melting and pouring liquid with certain requirements into casting, the cooling solidification, cleaning after processing a predetermined shape, size and performance of the castingprocess. Casting blank because almost forming, and achieve freemachining or a small amount of processing to reduce the cost and decrease the degree of time. Casting is one of the basic technology ofmodern manufacturing industry.
The development of casting
Casting is one of the basic technology of modern mechanical manufacturing industry, foundry industry development marks a national power production. China has become the world's one of the largest in the foundry machinery, casting machinery manufacturing industry has madegreat achievements in recent years.
"Eight five" during casting machinery manufacturing is the electrical and Mechanical Services Department attaches great importance toinvestment, since the founding of the largest a special technical improvement loans and research costs, support the development of foundry machinery products. "Manufacturing" big shot blasting machine,"vertical parting flaskless shoot squeeze molding machine", "water glass sand equipment development" of old sand recycling, "metal castingequipment" and so on have been the development and application of.
"Nine Five" period, the foundry machinery industry bear and establish the completed "car casting blank refined efficient modeling and cleaningtechnology and complete sets of equipment in the mission", "research and development" cylinder efficient continuous shot blast cleaning linealso success, 1999 to complete the national attack off high levels of air impact molding line project success.
"Fifteen" period, an average annual increase of casting machinery industry main economic index was above 30%, higher than the industry average growth machine tools, especially the profit growth faster, with an average annual profit growth of up to 46%, but also maintain a higher level of sales market. In addition, resin sand casting equipment, basiccan meet the demand of domestic market, has changed in the pastmainly relied on imports of the situation; have been able to produceautomatic production line for casting high level, to be part of the import substitution level, part of the solution to the cylinder block, cylinder head and other castings will have to import the high level; automatic core making machine, automatic casting cleaning machine, automatic sandprocessing, large-scale automatic die casting machine and castingequipment, casting machinery, domestic basically can manufacture. It should be said that the "level of casting machinery industry fifteen"period has been greatly improved, as Chinese foundry machinery industry further development and lay the good foundation.
"Eleven five" period, the foundry industry stimulated by the huge market demand, will continue to maintain a high rate of growth. Due to the technical level of foundry machinery products still and larger market demand gap, so that the development of the industry development and expansion of the enormous space, bring opportunities for the rapid growth of foundry machinery industry.
