Innovative Application of Aluminum Alloy Die Casting in the Field of New Energy Vehicles

With the booming development of the new energy vehicle industry, lightweight and high-efficiency have become the core directions of technological innovation. Aluminum alloy die-casting, with its excellent comprehensive performance, has demonstrated many innovative applications in the field of new energy vehicles.

In terms of body structure, traditional car bodies often use stamping and welding processes, with a large number of components and heavy weight. Aluminum alloy die-casting technology integrates dozens or even hundreds of stamping and welding parts into 1-2 large die-casting parts through an integrated die-casting process, greatly reducing the number of components and welding points, reducing the weight of the vehicle body, and improving production efficiency and structural strength of the vehicle body. Tesla is the first to apply integrated die-casting flooring, reducing weight by over 30% and shortening production cycle by 40%, setting a benchmark for the industry.

As the "heart" of new energy vehicles, the battery system has extremely high requirements for heat dissipation and safety performance. Aluminum alloy die-casting technology can manufacture battery cases with complex structures. Its good thermal conductivity and strength can efficiently dissipate battery heat and provide reliable physical protection for the battery. For example, some car companies use aluminum alloy die-casting battery trays to achieve liquid cooling and heat dissipation through internal flow channel design, ensuring the temperature stability of the battery under different working conditions.

In the application of motor components, aluminum alloy die-casting parts have become an ideal choice for motor housings, end caps, and other components due to their lightweight, high strength, and good electromagnetic shielding performance. Compared to traditional steel materials, aluminum alloy die-casting parts reduce weight by about 40%, which helps to reduce vehicle energy consumption and improve driving range. At the same time, precision die-casting technology can achieve one-time molding of complex structures, meeting the design requirements of compact and integrated motors.

Aluminum alloy die-casting technology is driving the development of new energy vehicles towards lighter, more efficient, and safer directions through innovative applications. In the future, with the continuous progress of technology, its application prospects in the field of new energy vehicles will be even broader.
