Chinas 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. China is a big foundry country. The annual output of castings, the number of employees and enterprises have ranked first in the world. With the strengthening of the trend of economic globalization and the continuous development of market economy, casting related technology, production and management are increasingly dependent on various standards. 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 automobile lightweight: first, the requirements of automobile for aluminum castings are developing towards thin-walled, complex shape, high strength and high quality. In order to meet this requirement, it is necessary to further optimize the casting process and develop new alloy materials. Second, we should reduce production costs from the point of view of design and technology, such as the use of a variety of technologies and automation technologies to increase productivity, extend the service life of dies, and reduce the number of parts by integrated design. Thirdly, computer simulation technology is used to shorten the development cycle of process plan. Fourth, increase the recovery of aluminum. Recycled aluminum is the main raw material of aluminum casting. While developing the foundry industry in China, we should pay attention to the utilization of recycled aluminum resources, develop the technology of effective separation of aluminum from the waste materials of composite materials and heterogeneous materials, and establish a wide waste recycling system.
