　　The problems behind the prosperity of aluminum alloy die-casting

　　The recorded origin of aluminum alloy die-casting dates back to the early 20th century, when Wagner designed the gooseneck pressure die-casting machine before officially joining the die-casting family. Today, aluminum alloy die-casting is widely used due to its superior die-casting performance and usability, especially in the automotive manufacturing industry, which is highly regarded as the future of automotive manufacturing. However, hidden beneath the bustling exterior are undeniable issues.

　　The development of die-casting industry and automobile manufacturing industry has always been closely related. The rapid development of automobile manufacturing industry has brought huge market demand to die-casting industry, and the share of die-casting parts supplied to the automobile industry continues to expand. Automobile manufacturing is one of the important pillars of die-casting industry development. However, looking back at the history of automobile manufacturing, it is not difficult to find that more and more parts in automobiles are being manufactured using die-casting technology. This not only demonstrates the superiority of die-casting technology, but also shows that die-casting industry is also one of the pillars of the automobile industry.

　　At present, people's requirements for automobiles are increasingly towards high performance, low pollution, low energy consumption, lightweight, pollution-free, corrosion-resistant, and high hardness aluminum alloy die-casting parts, which have become the first choice for automobile manufacturing. However, aluminum alloy die-casting also has undeniable disadvantages, such as poor formability, surface defects such as pores and sand holes, insufficient dimensional accuracy, and difficult surface treatment. This is suitable for some parts in automobiles that do not care about appearance and only focus on performance. If it is a product that pays more attention to aesthetics, the cost of using aluminum alloy die-casting is higher, but the delivery time is also longer.
