Because the metal copper, zinc, aluminum and aluminum alloy has good fluidity and plasticity, and casting processing is in the pressure die-casting machine, so aluminum die-casting parts can make a variety of more complex shape, but also can make a higher precision and finish, thus largely reducing the amount of mechanical processing of the casting and metal copper, zinc, aluminum or aluminum alloy casting margin, not only save electricity, metal materials, but also greatly Save labor costs; and copper, zinc, aluminum and aluminum alloy has excellent thermal conductivity, small specific gravity and high machinability; thus die casting is widely used in various industries such as automobile manufacturing, internal combustion engine production, motorcycle manufacturing, motor manufacturing, oil pump manufacturing, transmission machinery manufacturing, precision instruments, landscaping, power construction, construction decoration.

With the downstream manufacturing industry gradually gathered to China, China's die-casting industry also with China's overall level of industrialization has improved the development of a long way, and gradually developed into a world die-casting power. From the point of view of die-casting output, with China's automobile, communication infrastructure equipment, 3C products, equipment manufacturing, home appliances, mechanical and electrical instruments, light industry and other industries continue to develop rapidly, as well as foreign die-casting industry to China transfer, China's die-casting industry has entered a new normal of stable growth.

With more and more high-end manufacturing industry production capacity to China, China's die-casting industry in the process of growth is also continuing to upgrade the structure, precision die-casting ratio gradually increased. China die-casting products for the automotive industry has been more than 70% of the proportion of the developed countries and reached the basic level.

As the most important category of die-casting industry products, automotive parts, especially the demand for automotive aluminum alloy die casting will largely affect the overall development prospects of the die-casting industry. From the perspective of the entire structure of the car, in addition to the car engine, transmission, transmission system, steering system, electronic control system using a large number of precision die casting, body frame and other large components also began to use aluminum alloy die casting.

In recent years, with the development of the global economy, automotive, 3C products, communications infrastructure equipment, household appliances, medical equipment and many other areas of the demand for precision die castings has grown steadily.

At present, the developed countries die casting market maturity is higher. With the improvement of die-casting equipment and process technology, more and more ferrous metal castings are replaced by non-ferrous metal die castings such as aluminum and magnesium alloys. The global production and consumption of die casting is mainly concentrated in the United States, China, Italy, Germany, Mexico, Japan and other countries.

For developed countries, due to the leading edge in the level of equipment and technology, so its die-casting industry is generally automotive, communications, aviation and other high quality and high value-added die-casting.

The number of die-casting enterprises in developed countries is less, but the scale of individual enterprises is larger, the degree of specialization is higher, in terms of capital, technology, customer resources, etc. has a strong advantage.

According to the "2022-2026 automotive aluminum alloy die casting industry status research and development prospect research report" released by Hangzhou Zhongjing Zhisheng Market Research Co., Ltd: China's economy maintains the momentum of rapid development. Due to the increasing contradiction between resources and the environment, according to the requirements of the scientific concept of development, circular economy and clean production has become an important national policy for sustainable socio-economic development. Experts pointed out that the die-casting category, that includes low-pressure casting and extrusion casting and other non-ferrous metal casting molding process under various pressure, its total output is about 1.5 million tons. It is understood that the total national automobile production reached 7.28 million units, an increase of 27.6%, including car production of 3.87 million units, an increase of 39.7%. The national total output of die casting 1024000 tons, including: aluminum die-casting parts 802,140 tons, magnesium die casting 136,020 tons. National car production 3,850,100 units, an increase of 23.4%; sales of 3,601,000 units, an increase of 22.0%. Die-casting market will continue to maintain rapid growth trend. Die-casting non-ferrous metal resources can be recycled and die-casting less cutting process is advanced, especially adapt to the requirements of circular economy and clean production, in line with the general policy of national economic development. Automotive lightweight, more accelerated the development of aluminum and magnesium die casting market; international non-ferrous metal die casting production center of gravity to China has become an inevitable trend, die-casting market development space is huge.

The so-called automotive lightweight, is to ensure the strength and safety performance of the premise of the car, as far as possible to reduce the overall quality of the car, so as to improve the car's dynamics, reduce fuel consumption, reduce exhaust pollution. For the whole vehicle lightweighting, different parts can have different degrees of contribution. The lightweighting of body, interior and exterior decoration and power system is of great significance to reduce energy consumption during the driving process of the car. Aluminum material has the characteristics of light weight, recyclable and easy to be molded. Theoretically, aluminum cars can reduce weight up to 30%-40% than steel cars, among which aluminum engines can reduce weight by 30%, aluminum radiators are 20%-40% lighter than copper ones, all-aluminum bodies can reduce weight by more than 40% than steel ones, and aluminum wheels of cars can reduce weight by 30%. Therefore, aluminum alloy material is one of the most ideal materials for automobile lightweighting.

Due to the consideration of reducing greenhouse gas emissions and reducing the dependence on fossil energy, the requirement of fuel consumption index of automobiles has been rising, and the average fuel economy standard ( Corporate Average FuelEconomy) forces automakers to take the lightweight route to reduce fuel consumption. Lightweighting, as one of the key technologies for automotive energy efficiency, has significant energy-saving effects. A 10% weight reduction in gasoline passenger cars can reduce fuel consumption by 3.3%, and a 15% weight reduction can reduce fuel consumption by 5%; for diesel passenger cars, it can reduce fuel consumption by 3.9% and 5.9%, respectively.
