In the die casting market, the automobile industry has a very large share. According to relevant statistics, although the automobile industry accounts for different shares due to different labor structures in different countries, the above proportion always ranks first. From the end of the 20th century to the beginning of the 21st century, the proportion of die-casting parts in the automobile industry is about 48-80%. For example, Australia accounts for 80%, Japan for 79%, Spain for 65%, China for 64.5 (including automobiles and motorcycles), Germany for 61%, India for 60%, Canada for 49%, and the United States for 48%. According to recent reports, the proportion in the United States has risen to about 75%. The automobile industry occupies such a huge share in the die casting industry, which shows its important position in the die casting industry. As far as China is concerned, this proportion has been kept between 65% and 75% in recent years (including vehicles, motorcycles and other means of transportation). As far as the automobile industry is concerned, this proportion has also increased dramatically year by year.
 
 
 
 
As for the number of die-casting parts used in each vehicle, it is reported (taking American data as an example) that in the early 1980s, the average weight of each vehicle was in the range of 1315-1542kg, and then decreased year by year. Taking the consumption of aluminum alloy castings per vehicle as an example, it is gradually increasing. In 1980, the average consumption per vehicle was 34kg, in 1990, 68kg, in 2000, 1113kg, and in 2009, 175KG. Aluminum alloy castings accounted for more than 65% of all aluminum castings.
 
 
 
 
In addition, in addition to aluminum alloy die-casting, zinc alloy, magnesium alloy and copper alloy die-casting are also used in cars, so the number of die-casting parts for each car is imaginable. Die casting industry is closely related to automobile industry.
 
 
 
 
Looking back on the development history of the world automobile industry, in the process of design and application of various parts, great importance is attached to the use of die-casting parts, especially the complex, large and important parts, which are usually listed as the main parts. Research topics. This not only shows that the die-casting industry is irreplaceable in this respect, but also highlights that the development of the die-casting industry is largely based on the automobile industry. In other words, die casting industry is one of the important pillar industries of automobile industry.
 
 
 
 
Nowadays, people's demand for cars is higher and higher, performance is higher and higher, pollution is low, energy consumption is low. There are two ways to reduce the energy consumption of automobiles: one is to improve the power system; the other is to reduce the weight of automobiles, that is, to quantify the number of automobiles. The most effective way to realize lightweight is to make auto parts with lightweight materials. In the 1970s, aluminum alloy castings (including all kinds of casting methods) were widely used to replace castings as important parts of automobiles in various countries.
