Foundry industry trends

The trend in the development of foundry products is to require castings with better overall performance, higher precision, less machining allowance and a smoother surface. In addition, the requirements for energy conservation and the voice of society to restore the natural environment are also increasing. In order to meet these requirements, new casting alloys will be developed, and new smelting processes and new equipment will emerge. As the degree of mechanization automation in foundry production continues to increase, more will be developed towards flexible production to expand the adaptability to different batch castings and multi-species production. New technologies for energy and raw materials will be given priority, and new processes and new equipment with little or no pollution will be given priority. Quality control technology will have new developments in the detection, non-destructive testing and stress measurement of various processes.

The development of the foundry industry, 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. According to statistics in 2008, China's annual output of 33.5 million tons of castings is the world's largest casting country.

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 the largest 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 “finishing and refining high-efficiency modeling and cleaning technology for car castings”, and the development and development of “high-efficiency continuous shot blasting line for cylinders” was also successful. In 1999, the country successfully completed the 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 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%, while maintaining Higher market sales levels. In addition, the resin sand molding 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 import level, and partially solve the car engine. Castings such as cylinders and cylinder heads must also be imported; casting machines such as high-level automatic core making machines, automatic casting cleaning machines, automatic sand processing machines, large-scale automatic die-casting machines, and precision casting equipment can be manufactured in China. . It should be said that during the "10th Five-Year Plan" period, the product level of the foundry machinery industry 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 equipment manufacturing industry will continue to maintain a relatively high growth rate under the stimulation of international and domestic 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.
