1. Overview of die casting
The metal materials used for die casting are mainly aluminum alloys, magnesium alloys, zinc alloys and copper alloys. Since aluminum alloy die castings are widely used in the automotive industry, they account for a relatively high proportion of die castings. According to statistics from the China Foundry Association, aluminum alloy die castings account for about 85% of die castings.
2. Overview of the die casting industry market
(1) Overview of the international market
In recent years, with the development of the global economy, the demand for precision die castings in many fields such as automobiles, 3C products, communication infrastructure, household appliances, and medical equipment has been steadily increasing.
At present, the die-casting market in developed countries is relatively mature. With the improvement of die casting equipment and process technology, more and more ferrous metal castings have been replaced by non-ferrous metal die castings such as aluminum alloys and magnesium alloys. Global production and consumption of die castings are mainly concentrated in the United States, China, Italy, Germany, Mexico, Japan and other countries.
For developed countries, due to their leading advantages in terms of equipment and technology, their die-casting industry generally focuses on high-quality and high-value-added die-casting such as automobiles, communications, and aviation.
The number of die-casting enterprises in developed countries is relatively small, but the size of a single enterprise is large and the degree of specialization is high. It has strong advantages in terms of capital, technology and customer resources.
According to the data of "State of the Industry Report and Research Development" released by NADCA in October 2013, my country was the world's largest producer of die castings in 2012, accounting for 34% of global output.
(2) Overview of the domestic market
As the downstream manufacturing industry gradually gathers in China, my country's die-casting industry has also made great progress with the improvement of China's overall industrialization level, and gradually developed into a world die-casting country. Judging from the output of die castings, with the continuous and rapid development of China's automotive, communications infrastructure, 3C products, equipment manufacturing, home appliances, electromechanical instruments, light industry and other industries, and the transfer of foreign die casting industries to China, China's die casting industry has entered The new normal of steady growth.
As more and more high-end manufacturing industries shift their production capacity to China, China's die-casting industry continues to upgrade its structure during the growth process, and the proportion of precision die-casting parts has gradually increased. As of the end of 2013, the proportion of China's die-casting products used in the automotive industry has exceeded 70%, reaching a level that is basically the same as that of developed countries.
As the most important category of products in the die-casting industry, the demand for automotive parts, especially automotive aluminum alloy die-casting parts, will greatly affect the overall development prospects of the die-casting industry. From the perspective of the structure of the entire car, in addition to the use of a large number of precision die castings for car engines, gearboxes, transmission systems, steering systems, and electronic control systems, large components such as body frames have also begun to use aluminum alloy die castings.
3. Overview of the automotive die casting industry market
As the most important application field of die-casting products, a large number of precision die-casting parts are used in automobile engines, gearboxes, transmission systems, steering systems, and electronic control systems. The demand for auto parts will greatly affect the overall development of the die-casting industry prospect.
As people pay more and more attention to automobile energy conservation and environmental protection, the automotive industry has shown a trend of replacing steel and iron with aluminum in the past three decades. This trend is still continuing. At present, the global automotive aluminum die-casting market as a whole shows a rapid development trend. It is expected that global sales in 2025 will reach 16.6352 million tons, an increase of 83.19% over 2012.
In addition, in addition to aluminum alloy die castings, zinc alloy, magnesium alloy and copper alloy die castings are also used in automobiles
The automotive industry's demand for aluminum, zinc and other metal die castings will continue to grow in the future, which is mainly affected by the following factors:
(1) my country's auto industry will still maintain a rapid development rate
Since the reform and opening up, with the rapid growth of my country's economy, the automotive industry has also made great strides. In 1980, my country's automobile production was 223,200, and by 2016 it had increased to 28.12 million, an increase of 125.49 times. In recent years, affected by the international and domestic economic situation, the growth rate of my country's automobile output has declined, but due to the high base, the annual increase in automobile output still has a considerable scale.
In 2016, my country's private car ownership was 146 million, with 36 cars per 100 households, far below the level of developed countries. Therefore, my country's auto industry still has more room for development in the future.
(2) Lightweight trends of automobiles
The so-called light-weight of automobiles means that on the premise of ensuring the strength and safety performance of automobiles, the curb quality of automobiles is reduced as much as possible, so as to improve the power of automobiles, reduce fuel consumption and reduce exhaust pollution. For the light weight of the whole vehicle, different parts can have different degrees of contribution. The light weight of the body, interior and exterior trim, and power system is very important for reducing energy consumption during the driving of the car. Aluminum alloy materials are light, recyclable and easy to form. In theory, aluminum cars can reduce weight by 30%-40% compared to steel cars, of which aluminum engines can reduce weight by 30%, aluminum radiators are 20%-40% lighter than copper, and all-aluminum bodies can reduce weight by 40% than steel More than %, automobile aluminum wheels can reduce weight by 30%. Therefore, aluminum alloy material is one of the most ideal materials for automobile lightweight.
(3) The development of new energy vehicles will further promote the demand for metal die castings
One of the main problems of current new energy vehicles is that the cruising range is short, and lightweight design has become the main measure for reducing weight and consumption of new energy vehicles. Take Tesla (TESLA) Model S (parameter|picture) as an example, its total weight reaches 2,108kg, and the battery weight exceeds 500kg, in addition to the drive motor to increase the weight of the vehicle; while the total weight of the engine of traditional cars is generally 80-160kg. The mileage of a 70L gasoline car can reach 700-900Km, while the range of an electric car with a 500kg battery is only about 400Km. Therefore, increasing the proportion of automobile aluminum alloy die castings is the main measure for lightweighting new energy vehicles.
New energy vehicles have stricter body weight requirements than traditional energy vehicles, so they use lighter aluminum alloy die-casting parts. For example, 95% of the Tesla (TESLA) Model S series models use aluminum alloy materials. The continued high-speed growth of new energy vehicles will form a strong impetus for the development of the automobile aluminum alloy die-casting industry
Auto parts are the various units that make up a vehicle, and are products that provide services to cars. There are many types of auto parts. With the improvement of people's living standards, people's car consumption is also increasing, and the auto parts market is also growing.
