Aluminum alloy casting has many advantages, which makes it the development direction of the casting industry and one of the most popular casting products for purchasing customers. In the future, with the progress of aluminum alloy casting technology, it will show its style on a larger stage.
Analysis of problems urgently needed to be solved in the future development of domestic
aluminum alloy casting industry
Reducing energy consumption, reducing environmental pollution and saving limited resources is a very important and urgent task facing all countries today
(aluminum casting). Driven by the general trend of lightweight products such as automobiles, it can be predicted that China's light metal casting market will develop greatly in the next 10 years. The proportion of aluminum and magnesium alloy castings in major casting producing countries is between 13% and 19%, and in some countries (such as Italy), it is as high as 30% ~ 40%, while the proportion of aluminum and magnesium alloy castings in China is less than 10%. More than 90% of aluminum castings in developed countries are used in automobile parts manufacturing. In China, 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 automobile for aluminum castings are developing in the direction of thin wall, complex shape, high strength and high quality. In order to meet this requirement, the casting process should be further optimized and new alloy materials should be developed. Second, the first mock exam should be done to reduce production costs from the point of view of design and process, such as using a variety of modules and automation technologies to increase productivity and prolong the service life of dies. Thirdly, computer simulation technology is adopted to shorten the development cycle of process scheme. Fourth, increase the recovery of aluminum. Recycled aluminum is the main raw material of aluminum casting. While developing the casting industry, China should pay attention to the utilization of recycled aluminum resources, develop the technology of effective separation of aluminum from the waste of composite materials and heterogeneous materials, and establish an extensive waste recycling system.
