Development trend of foundry industry

More than 80% of the products in the foundry industry are made by sand casting, so we usually refer to sand casting, that is, sand casting.

During the Eighth Five Year Plan period, the former Ministry of mechanical and Electrical Engineering attached great importance to foundry, invested the largest special technical transformation loan and key research expenses 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 shot blasting cleaning machine”, “vertical parting box less injection molding machine”, “development of used sodium silicate sand regeneration 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 industry undertook and completed the task of “complete set of technology and equipment for refined and efficient modeling and cleaning of car casting blanks”, and the development and development of efficient continuous shot blasting cleaning line for cylinder block also achieved complete success. In 1999, it completed the success of the national high-level air impact molding line project.

During the Tenth Five Year Plan period, the average annual growth of the main economic indicators of the foundry industry was more than 30%, which was higher than the average growth level of the whole machine tool industry. In particular, the profit grew faster, with an average annual profit growth of 46%, while maintaining a high market sales level. In addition, the complete set of resin sand casting equipment can basically meet the needs of the domestic market and change the situation of mainly relying on imports in the past; It has been able to produce a high-level automatic casting production line, which can partially replace the import level, and partially solve the problem that the casting blanks such as car engine cylinder block and cylinder head also need to be imported; Casting machines such as high-level automatic core making machine, automatic casting cleaning machine, automatic sand processor, large-scale automatic die casting machine and precision casting equipment can be basically produced and manufactured in China. It should be said that during the Tenth 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 foundry industry will continue to maintain a high growth rate stimulated by the huge market demand. As the technical level of casting machinery products still lags far behind 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 casting machinery industry.

During the “12th Five Year Plan” period, the whole casting industry should work hard on new casting processes and new materials. The price of casting materials remains high, which requires the precision casting industry to develop new and replaceable low-cost new materials quickly; The continuous improvement of the requirements of downstream customers drives us to improve the process level; With the rising cost of human resources, we must make more efforts, develop and invest in precision casting equipment! For example, the new materials, special corundum for precision casting and the casting mobile phone people in Taiwan, which are unanimously recommended by the China Foundry Association and the International Foundry consulting network, are the next development direction of precision casting.
