Integrated Die Casting Process For Auto Parts

Die-casting is a revolutionary technology. At present, die-casting aluminum alloy products account for about 54% to 70% of aluminum for automobiles. Again, die-cast into 1-2 large aluminum castings. Integrated die-casting meets the needs of cost reduction and light weight for new energy vehicles.

1. Advantages of aluminum alloy die casting auto parts:

①Reduce weight: Lightweight is a major trend in the development of the automotive industry. The weight of the Tesla Model Y is reduced by 30% after the use of one-piece die-casting, and the battery life is directly increased by 14%.

②Improve efficiency: Compared with the traditional process, the production process is simplified and the production efficiency is improved.

③ Reduce costs: Tesla uses this technology to reduce costs by 40%.

Die-casting technology is a special casting technology. At present, die-casting aluminum alloy products account for about 54% to 70% of aluminum for automobiles. Integrated die-casting technology is a new revolution in die-casting technology. By redesigning multiple independent parts that need to be assembled in the original design, and using a super-large die-casting machine to die-cast at one time, complete parts can be directly obtained to realize the original function.

The traditional manufacturing process of automobiles mainly includes four links: stamping, welding, painting, and final assembly. The integrated die-casting technology is an innovation to the traditional automobile manufacturing process, which can make the body lighter, save costs, improve efficiency, shorten the supply chain, shorten the manufacturing time and transportation time of the whole vehicle, reduce labor and robots, and increase the manufacturing scale.

2. Why is integrated die casting a development trend?

①Reduce weight: In the context of dual carbon, lightweight is a major trend in the development of the automotive industry. The application of integrated die-casting contributes to the realization of lightweight, and the weight of the Tesla Model Y rear floor assembly is reduced by 30% after the use of integrated die-casting.

②Improve efficiency: Compared with the existing production process, integrated die casting improves the production efficiency by simplifying the production process and improving the tact.

③Reduce costs: The application of integrated die-casting technology can reduce production, land, labor and other costs. Tesla rate applied the integrated die-cast rear floor, and the manufacturing cost was reduced by 40% compared with the original.

3. How big is the domestic market space for integrated die casting?

At present, Tesla has deployed integrated die-casting technology as a standard process, and many OEMs have followed up the layout of integrated die-casting technology. In the future, except for the cover parts, the stamping and welding of the rest of the body structure may be replaced by the die-casting process. The ASP of integrated die-casting parts is expected to continue to increase.

It is expected that the market space of integrated die casting will usher in a rapid increase from 2023. The market space of domestic integrated die casting is expected to reach a scale of more than 30 billion by 2025, and the CAGR from 2022 to 2025 will reach 238%.
