The development status of China's aluminium alloy die-casting industry from 2018 to 2025 shows that the production technology of aluminium alloy precision die-casting products mainly adopts metal die-casting manufacturing technology, which belongs to the metal products industry (C33) in the "Guidelines for Classification of Listed Companies".
At present, the macro-management functions of the metal products industry are undertaken by the National Development and Reform Commission and the Ministry of Industry and Information Technology, which are responsible for formulating industrial policies and guiding technological transformation.
China Foundry Association is the only national first-level foundry industry organization (association legal person) registered by the Ministry of Civil Affairs of China, which is voluntarily formed by foundry enterprises, local associations and foundry-related enterprises, research and design institutes, colleges and universities, among which the die-casting branch exercises industry management functions for the die-casting industry. The main functions of the Die Casting Branch of China Foundry Association are: to formulate and supervise the implementation of the rules and regulations of the industry, to establish and publicize industry self-discipline and self-management behavior, to oppose vicious low-price competition and the production of inferior products, to maintain a fair and competitive market order; to assist the government in formulating and revising relevant national standards and industry standards for the die casting industry, and to organize the formulation of die casting industry standards. Guidance documents of production process, investigation, collection and collation of basic information of domestic die casting industry and economic and technical information of foreign investment casting specialty, providing information for enterprise development and government formulation of industry development plan, etc.
II. Major Industrial Policies
Automobile die-casting enterprises are not only affected by the laws, regulations and policies of the die-casting industry, but also very sensitive to the laws, regulations and policies of the automobile industry. At present, the automotive industry is transforming to new energy vehicles. Because of the insufficient battery mileage, new energy vehicles must reduce the body weight to achieve the purpose of improving user experience. Therefore, the development of new energy vehicles will promote the development of automotive aluminum alloy components. In addition, the emission standards of automobiles in various countries are constantly improving, and lighter body weight will reduce the engine power lifting pressure and effectively meet the energy saving and emission reduction standards. Therefore, body lightweight is imminent, and the trend of automobile lightweight manufacturing has been formed. China's central and local governments have issued a series of policies to support and encourage the automotive industry and related industries of energy-saving and environmental protection materials.
1. Overview of International Market
In recent years, with the development of global economy, the demand for precision die castings in automobile, 3C products, communication infrastructure, household appliances, medical equipment and many other fields has increased steadily.
At present, the market maturity of die castings in developed countries is relatively high. With the improvement of die casting equipment and technology, more and more ferrous metal castings are replaced by non-ferrous metal die castings such as aluminium alloy and magnesium alloy. 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 equipment and technology level, the die-casting industry is generally dominated by high-quality and high value-added die-casting such as automobiles, communications, aviation and so on. The number of die-casting enterprises in developed countries is relatively small, but the scale of individual enterprises is large and the degree of specialization is high. They have strong advantages in capital, technology, customer resources and so on.
2. Overview of Domestic Market
With the downstream manufacturing industry gradually gathering in China, China's die-casting industry has also been greatly developed with the improvement of China's overall industrialization level, and gradually developed into a world die-casting power. From the output of die casting, with the sustained and rapid development of China's automobile, communication infrastructure, 3C products, equipment manufacturing industry, household appliances, electromechanical instruments, light industry and other industries, as well as the transfer of foreign die casting industry to China, China's die casting industry has entered a new normal state of steady growth.
As more and more high-end manufacturing industries shift their production capacity to China, China's die casting industry is continuing to upgrade its structure in the process of growth, and the proportion of precision die castings is gradually increasing.
As one of the most important products in die-casting industry, the demand of automotive parts, especially automotive aluminium alloy die-casting parts, will greatly affect the overall development prospects of the die-casting industry. From the point of view of the structure of the whole automobile, besides a large number of precision die-castings used in automobile engine, gearbox, transmission system, steering system and electronic control system, large components such as body frame have also begun to use aluminum alloy die-castings.
IV. General Situation of 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 automotive engine, gearbox, transmission system, steering system and electronic control system. The demand of automotive parts will greatly affect the overall development prospects of the die-casting industry.
With people's increasing attention to energy saving and environmental protection of automobiles, the automotive industry has shown the trend of replacing steel and iron with aluminium in the past 30 years, and this trend is still continuing.
V. Trends in Automotive Die Casting Industry
1. Trend of Automobile Lightweight
The so-called vehicle lightweight is to reduce the vehicle's overall quality as much as possible under the premise of guaranteeing the strength and safety performance of the vehicle, so as to improve the power of the vehicle, reduce fuel consumption and reduce exhaust pollution. For vehicle lightweight, different parts can contribute to varying degrees. The lightweight of body, interior and exterior trim, power system is very important to reduce energy consumption in the process of vehicle driving. Aluminum alloy material has the characteristics of light weight, recyclability and easy forming.
Reducing vehicle weight can reduce engine load, improve vehicle driving performance, effectively reduce braking distance, make the steering and bending process more flexible, thus making the vehicle more stable, and the aluminum alloy structure can absorb and disperse more energy when impacted, so it is more comfortable and safe. Affected by this, the aluminium permeability of the main components of automobiles will increase significantly in the next ten years.
2. Needs of metal die casting pulled by downstream new energy automobiles
The development of new energy vehicles will further promote the demand for metal die castings. One of the main problems of new energy vehicles is the short range. Lightweight design has become the main measure to reduce the weight and consumption of new energy vehicles. A 70L gasoline car can travel 700-900 Km, while an electric car with 500 kg batteries can only travel about 400 Km. Therefore, increasing the proportion of automotive aluminium alloy die castings is the main measure to lighten new energy vehicles.
With the release and implementation of China's automobile energy saving and emission reduction policy, new energy vehicles in recent years have shown a rapid development trend. In the first quarter of 2018, the production and sales of new energy vehicles reached 150,000 and 143,000 respectively, up 156.9% and 154.3% respectively. It can be seen that the transition period of the new energy vehicle subsidy policy does not seem to affect the sales of electric vehicles.
Aluminum alloy die castings are conducive to the development of new energy automobile industry, while the continuous high growth of new energy automobile will continue to promote the development of aluminum alloy die castings industry.
