The casting industry in China has always been an important, fundamental, and irreplaceable industry in the national economy, with the advantages of relatively low cost and wide process adaptability. China is a major foundry country, ranking first in the world in terms of annual production of castings, as well as the number of employees and enterprises. With the strengthening of the trend of economic globalization and the continuous development of the market economy, the demand and dependence on various standards in casting related processes, production, management, etc. are increasing. In China, there are still many problems to be solved in order to form large-scale production of aluminum alloy castings and meet the requirements of automotive lightweight. Firstly, the requirements for aluminum castings in automobiles are developing towards thin-walled, complex shapes, high strength, and high quality. To meet this requirement, further optimization of the casting process and 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 the first mock examination multi part technology and automation technology to improve productivity and extend the service life of the mold, and the use of integrated design to reduce the number of parts. Thirdly, using computer simulation technology to shorten the development cycle of process plans. Fourthly, increase the recycling efforts of aluminum. Regenerated aluminum is the main raw material for aluminum casting. While developing the casting industry in China, attention should be paid to the utilization of recycled aluminum resources, the development of effective separation technology for aluminum from waste materials composed of composite and dissimilar materials, and the establishment of a wide range of waste recycling systems.
Our company has rich experience in the casting industry and has a casting history of over 70 years. Our aluminum castings have low casting costs, good processability, and save resources and energy through remelting and regeneration. Sand casting is preferred for aluminum castings, mainly due to its lower cost, simpler production process, and shorter production cycle compared to other casting methods. After artificial heating, it is transformed into aluminum alloy liquid or molten state, and then poured into the mold cavity through professional molds or corresponding processes. After cooling, it is formed and taken out. The commonly used methods for casting aluminum parts include sand casting, die casting, low-pressure casting, precision casting, permanent mold, lost foam casting, etc. Aluminum castings, due to their excellent properties such as low density, high specific strength, and corrosion resistance, will be more widely used in various industries such as aviation, aerospace, automotive, and machinery. Highly praised by customers. Especially in the automotive industry, replacing steel and aluminum castings with aluminum and nickel alloy castings to reduce fuel consumption and improve energy utilization is a long-term development trend. Among them, the focus is on solving the pollution-free, efficient, and easy to operate refining technology, modification technology, grain refinement technology, and rapid detection technology in front of the furnace. To further improve material performance and maximize the potential of materials, 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 aluminum alloy melting process, continue the development and research of aluminum alloy die-casting and squeeze casting processes and related technologies, and improve the development and research of aluminum alloy melting equipment and related technologies and processes.
