After more than 40 years of development in China's motor industry, especially the rapid development of more than 20 years of reform and opening up, the small motor manufacturing industry has begun to develop in the direction of scale, standardization and automation, while the large and medium-sized motor manufacturing industry has been increasing the capacity of single machines. The direction of specialization, diversification, and customization. Made great progress. According to the previous research data, the rapid development of new energy has driven the rapid growth of the stepper motor industry, and the development prospects of China's motor industry are promising. At the same time, the CNC machining center is also the development trend of the entire industry for high-efficiency and energy saving. Small motor manufacturing industry will develop along the three major trends. The
With the continuous development of the motor industry, the extension and connotation of motor products are also expanding. Motor products are widely used in metallurgy, power, petrochemical, coal, mining, building materials, papermaking, municipal, water conservancy, shipbuilding, port handling an21, Application of Aluminum Alloy Die Casting in Automobile
With the continuous development of the automotive industry, the application of aluminum alloy die castings in automobiles has become more and more widespread. However, at present, there are fewer aluminum components used in the automotive industry in China, which is especially relevant to the development of the automobile industry in China. The current situation in the development of automobile production is very uncoordinated. Therefore, it is of great significance to accelerate the development and application of aluminum alloy die castings in domestic automobiles. The application of die castings is very wide, involving a large number of product areas and industrial categories. In all of these applications, the automobile industry should be decisively promoted in terms of quantity, variety, strict requirements, high quality, and large amounts of metal materials.
In the die-casting market, the share of the automotive industry is extremely impressive. Although the share of the auto industry varies from country to country, the above-mentioned share is always at the top. From the end of the 20th century to the beginning of the 21st century, the proportion of the total supply of die castings to the automotive industry was between 48 and 80%. For example: Australia accounted for 80%, Japan accounted for 79%, Spain 65%, China 64.5% (including cars and motorcycles), Germany 61%, India 60%, Canada 49%, the United States 48% and so on. According to recent reports, the proportion of the United States has risen to about 75%.
The automotive industry's use of die castings has such a huge share, which shows its important position in the die-casting industry. As far as China is concerned, this proportion has been maintained between 65 and 75% in recent years (including vehicles such as cars and motorcycles). In terms of auto parts alone, this proportion also shows a trend of significant increase year by year. For a long time, the automotive industry has been the largest market for the die-casting industry. According to statistics, the automotive industry has maintained rapid growth over the past five years, with an average annual increase of 24%, from 2 million in 2000 to 18 million in 2010. The output of automotive castings reached 11.48 million tons. It is estimated that in 2015 China's auto sales will reach 43 million. As a result, the development of the automobile industry in China has also driven the die-casting industry into a new period of development.
As for the use of die castings in each car, in the early 1980s, the average weight of each car was generally in the range of 1315 to 1542 Kg (due to the type of vehicle), and thereafter decreased year by year. If the amount of aluminum alloy castings in each car is used, it is gradually increasing. In 1980, the average per car was 34Kg, in 1990 it was 68kg, by 2000 it had increased to 111.3kg, and in 2009 it reached 157kg, among which aluminum alloy die castings. It accounts for more than 65% of all aluminum castings. In addition, in addition to aluminum alloy die castings, zinc-alloy, magnesium alloy and copper alloy die castings are also used in automobiles. Thus, the amount of die castings per vehicle can be imagined.
d other fields. The universality of the motor has gradually developed toward the specificity, which has broken the past situation where the same motors were used for different types of loads and different occasions. The motor is developing in the direction of specificity, particularity, and individuality. Many domestic companies are also transitioning to specialized enterprises, such as coal mine motor plants, explosion-proof motor plants, and micro-motor factories. Whether or not an enterprise has non-standardized and customized adaptability is an important aspect of measuring a company's future development potential.
