What is Casting and the Development of Casting

Casting

Casting is a process in which metal is smelted into a liquid that meets certain requirements and poured into a mold. After cooling, solidification, and cleaning, a casting with a predetermined shape, size and performance is obtained. The casting blank is almost formed, and the purpose of free machining or a small amount of processing reduces the cost and reduces the time to a certain extent. Casting is one of the basic processes of the modern manufacturing industry.

Foundry Development

Casting is one of the basic processes of modern machinery manufacturing industry, so the development of the foundry industry marks the production strength of a country. my country has now become one of the world's largest foundry machinery countries, 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 Services, which invested the largest special technical transformation loan and research expenses since the founding of the People's Republic of China, which supported the development and development of products in the foundry machinery industry. "Manufacture of large-scale shot blasting machine", "vertical parting boxless injection molding machine", "development of sodium silicate sand recycling equipment", "metal mold casting equipment" and so on have been developed and applied one after another.

During the "Ninth Five-Year Plan" period, the foundry machinery industry has undertaken and established the task of "complete technology and equipment for refined and efficient modeling and cleaning of car casting blanks", and "development and development of high-efficiency continuous shot blasting cleaning line for cylinder block" has also achieved complete success , In 1999, it completed the success of the national high-level gas punching molding line project.

During the "Tenth Five-Year Plan" period, the average annual growth rate of the main economic indicators of the foundry machinery industry was more than 30%, which was higher than the average growth level of the machine tool industry. Higher market sales levels. In addition, the complete set of resin sand casting equipment can basically meet the needs of the domestic market, changing the situation of mainly relying on imports in the past; it has been able to produce a high-level automatic casting production line, reaching a level that can partially replace imports, and partially solve the problem of car engines Cylinder block, cylinder head and other casting blanks are also imported; high-level automatic core making machine, automatic casting cleaning machine, automatic sand processor, large automatic die casting machine and Precision Casting equipment and other casting machinery can basically be produced in China. . It should be said that the product level of the foundry machinery industry has been greatly improved during the "Tenth Five-Year Plan" period, laying a good foundation for the further development of China's foundry machinery industry in the future.

During the "Eleventh Five-Year Plan" period, stimulated by huge market demand, the foundry industry will continue to maintain a relatively high growth rate. As the technical level of foundry machinery products is still far from the market demand, there is huge development potential and room for expansion in the development of the industry, bringing opportunities for the rapid growth of the foundry machinery industry.
