What is casting?
Casting is a process in which a metal is smelted into a liquid that meets certain requirements and poured into a mold, and which has a predetermined shape, size, and performance after being cooled and solidified. Casting blanks are near-formed to achieve machining-free or small-scale processing, reducing costs and reducing time to some extent. Casting is one of the fundamental processes in the modern manufacturing industry.
Development of casting
Casting is one of the basic processes of the modern machinery manufacturing industry, so the development of the foundry industry marks the production strength of a country. China has now become one of the world's largest casting 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. It invested in a special technical reform loan and research cost since the founding of the People's Republic of China, and supported the development and development of products in the foundry machinery industry. "Manufacturing of large-scale shot blasting machine", "vertical split type boxless injection molding machine", "development of water glass sand old sand recycling equipment", "metal casting equipment" and so on have been developed and applied.
During the "Ninth Five-Year Plan" period, the foundry machinery industry undertook and established the task of "cargo casting blank refining and cleaning complete sets of technology and equipment", and the "development and development of continuous shot blasting line for cylinders" was also a complete success. In the year, it successfully completed the national high-level gas-filling 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 above 30%, which was higher than the average growth rate of machine tools and the whole industry, especially the profit growth was faster, and the average annual profit increased by 46%. At the same time, it also maintains a high level of market sales. In addition, the resin sand casting complete equipment can basically meet the domestic market demand, changing the situation that relied mainly on imports in the past; it has been able to produce a higher level of automatic casting production line, which can partially replace the imported level, and partially solve the car engine. Castings such as cylinders and cylinder heads are also imported; high-level automatic core making machines, automatic casting cleaning machines, automatic sand processing machines, large-scale automatic die-casting machines, and casting equipment, etc., can basically be manufactured in China. It should be said that the product level of the foundry machinery industry during the 10th 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 relatively high growth rate under the stimulation of huge market demand. As the technical level of foundry machinery products still has a large gap with 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.
