Casting is a process in which the metal is melted into a liquid that meets certain requirements and poured into the mold. After cooling, solidification and cleaning, the process of obtaining a casting with a predetermined shape, size and performance is obtained. The casting blank is nearly shaped, and achieves the purpose of no machining or a small amount of machining, which reduces the cost and reduces the time to a certain extent. Casting is one of the basic processes of modern manufacturing industry.
development of casting
Casting is one of the basic processes of modern machinery manufacturing industry, so the development of casting industry marks the production strength of a country. At present, China has become one of the largest foundry machinery in the world, and has made great achievements in the foundry machinery manufacturing industry in recent years.
During the "Eighth Five-Year Plan" period, the foundry machinery manufacturing was highly valued by the former Ministry of Electrical and Mechanical Engineering, and invested a large special technical reform loan and research costs since the founding of the People's Republic of China, which supported the development and development of foundry machinery industry products. "Manufacturing of large shot blasting machine", "vertical parting boxless shot molding machine", "development of old water glass sand regeneration equipment", "metal mold casting equipment" and so on have been developed and applied.
During the "Ninth Five-Year Plan" period, the foundry machinery industry undertook and established and completed the task of "complete sets of technology and equipment for precision modeling and cleaning of car castings", and "the development and development of continuous shot blasting cleaning line for cylinder bodies" was also a complete success. In 1999, it completed the success of the national high-level air punching molding line project.
During the "Tenth Five-Year Plan" period, the average annual growth of the main economic indicators of the foundry machinery industry is above 30%, which is higher than the average growth level of the machine tool industry, especially the profit growth is faster, the average annual profit growth is as high as 46%, while also maintaining a high level of market sales. In addition, resin sand casting complete sets of equipment can basically meet the needs of the domestic market and change the situation of relying mainly on imports in the past; it has been able to produce a higher level of casting automatic production lines, reaching the level of partially replacing imports, and partially solving the problem of car engine blocks, cylinder heads and other casting blanks also need to be imported; high-level automatic core-making machine, automatic casting cleaning machine, automatic sand processing machine, large automatic die-casting machine and casting equipment and other casting machinery can basically be manufactured in China. It should be said that the product level of the foundry machinery industry during the "Tenth Five-Year Plan" period has been greatly improved, laying a good foundation for the further development of China's foundry machinery industry in the future.
During the "Eleventh Five-Year Plan" period, the foundry industry will continue to maintain a high growth rate under the stimulation of huge market demand. As the technical level of foundry machinery products is still far from the market demand, there is huge development potential and expansion space for the development of the industry, which brings opportunities for the rapid growth of the foundry machinery industry.
