Importance of China's Foundry Industry

China's foundry industry has always been an important, basic, and irreplaceable industry in the national economy, with the advantages of relatively low cost and wide process adaptability. my country is a large casting country, and its annual output of castings, as well as the number of employees and enterprises, has ranked first in the world. With the strengthening of economic globalization and the continuous development of market economy, the demand for and dependence on various standards such as casting-related crafts, production, and management is increasing. In my country, there are still many problems to be solved for aluminum alloy castings to form large-scale production and meet the requirements of automobile lightweight. First, the requirements of automobiles for aluminum castings are developing towards thin-walled, complex-shaped, high-strength, and high-quality directions. In order to meet this requirement, the casting process should be further optimized and the development of new alloy materials should be carried out. Second, the production cost should be reduced from the perspective of design and process, such as the use of one-mold multi-part technology and automation technology to increase productivity, extend the service life of the mold, and use an integrated design to reduce the number of parts. Third, use computer simulation technology to shorten the development cycle of the process plan. Fourth, increase the recovery of aluminum. Recycled aluminum is the main raw material for aluminum casting. While developing the foundry industry, my country should pay attention to the utilization of recycled aluminum resources, develop technologies to effectively separate aluminum from composite and dissimilar materials, and establish a wide range of waste recycling systems.

Our company has rich experience in the foundry industry. The aluminum castings we produce have low casting costs, good manufacturability, remelting and regeneration to save resources and energy. Aluminum castings prefer sand casting, mainly because sand casting is cheaper than other casting methods. , The production process is simple and the production cycle is short. After artificially heating it into liquid or molten aluminum alloy, pour liquid aluminum or molten aluminum alloy into the cavity through a professional mold or corresponding process, and take it out after cooling to form. Our commonly used aluminum casting methods are: sand casting, die casting, low pressure casting, Precision Casting, permanent mold, lost foam casting, etc. Because of its low density, high specific strength, and corrosion resistance, cast aluminum parts will be more widely used in aviation, aerospace, automotive, machinery and other industries. Well received by customers. Especially in the automobile industry, in order to reduce fuel consumption and improve energy utilization, it is a long-term development trend to replace steel and aluminum castings with aluminum and nickel alloy castings. Among them, it focuses on solving pollution-free, high-efficiency, easy-to-operate refining technology, metamorphism technology, grain refinement technology and rapid detection technology in front of the furnace. In order to further improve the material performance and maximize the potential of the material, high-quality aluminum alloy materials can be developed, especially aluminum castings that can meet the performance requirements of different working conditions; strengthen the research on the aluminum alloy melting process, and continue the aluminum alloy die casting and squeeze casting process And related technology development and research, perfect aluminum alloy smelting equipment and related technology and process development research.
