At present, the complete set of casting machinery in China is developing rapidly, and its development is also constantly adjusting its direction for better development in the future. The complete sets of domestic casting machinery will develop in the following four aspects in the future: first, to high-quality, efficient and green direction. Second, we should constantly strive to expand the production capacity of equipment and expand the scope of application. Third, with the goal of informatization of design and R&D, digitalization of equipment, intellectualization of production process and networking of business management, fully apply computer technology to achieve integration, intelligence, online and remote. Fourth, establish expert system, information processing system, and make full use of the Internet to realize remote research, remote demonstration, remote control box remote diagnosis. These four trends are the only way and mainstream for the future development of complete sets of foundry machinery in China. It will also promote the continuous development of China's casting machinery processing industry to a large extent. I believe that the complete sets of domestic casting machinery will go on a healthy and steady way of development.
In addition to a large number of factories, employees and large output, China's foundry technology lags behind developed countries in terms of quality, efficiency, energy and material consumption, working conditions and environmental protection. The reasons for these gaps are that the foundry site is small in scale, poor in economic strength, backward in technology and equipment, low in management level and low in the quality of employees. In order to eliminate these gaps, meet the needs of China's economic construction, and for the existence and development of the foundry technology industry itself, China's foundry technology industry should focus on improving the quality and economic benefits of castings, and face the domestic and international markets; Strengthen management, lay a good foundation and improve the quality of enterprises; Adjust the industrial structure of casting technology, reasonably allocate resources, and advocate moderate scale operation; We will continue to reform the foundry technology industry with advanced production processes and technical equipment to achieve cleaner production and ensure sustainable development.
The casting process is a process in which the metal is melted into a liquid meeting certain requirements and poured into the casting mold. After cooling, solidification and cleaning, the castings with predetermined shape, size and performance are obtained.
The casting process can be divided into three basic parts, namely, casting metal preparation, mold preparation and casting treatment. Cast metal refers to the metal materials used for casting in casting production. It is an alloy composed of a metal element and other metal or non-metallic elements. It is customarily called casting alloy, mainly including cast iron, cast steel and cast nonferrous alloy.
Casting technology is one of the main methods to obtain mechanical product blanks, is an important basic process of the casting machinery industry, and occupies an important position in the national economy. The current situation of China's foundry technology is that the output is large, with an annual output of about 12 million tons of castings, more than 20000 factories, and more than 1.2 million employees of foundry technology. One of the characteristics of China's foundry technology industry is the rapid development of township enterprises since the reform and opening up, which has become an important force in China's foundry technology industry. The number of township foundries has exceeded that of state-owned foundries, and the casting output of township foundries accounts for about half of the total casting output of the country.
The level of casting machinery is directly related to the development level of the casting industry. The current situation of China's casting machinery industry is difficult to meet the goal of moving forward from a large casting country to a strong casting country. The development of China's casting machinery industry has a long way to go.
