Tesla's successful application of mass-production integrated die-casting technology in the Model Y model has become a recent industry hotspot, and has attracted many new energy vehicle companies to follow suit.
The integrated die-casting technology has many advantages for the production of new energy vehicles. Compared with the existing production technology, it can improve the efficiency, reduce the cost and reduce the weight.
At present, Tesla has deployed integrated die-casting as a standard process.
At present, nearly 20 leading light alloy die-casting technology giants in China have deployed integrated die-casting technology.
As an outstanding representative, GDWC Precision Die Casting Technology Corporation has successively supplied aluminum alloy body structural parts in batches to Mercedes-Benz, Tesla, NIO, Xiaopeng, etc., and is accelerating product development. Trial production of integrated aluminum alloy rear floor products.
Integrated die-casting technology is a new change 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 design. Function.
Especially in the current hot new energy vehicle field, the integrated die-casting technology can "make a big difference". It is understood that 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.
To say that the recent popularity of integrated die casting is also due to Tesla. Tesla proposed this technology as early as 2019, and successfully simplified the rear bottom plate, which originally required more than 70 parts to be welded, into one or two one-time stamping and forming die-casting parts.
Because the material used for integrated die casting is heat-free aluminum alloy, it is lighter than traditional high-strength steel. For new energy vehicles, "weight reduction" is very important, so that you can bring a little less battery. Although the cost of aluminum alloy is relatively more expensive, the saved battery material and labor costs can be made up. According to Tesla's assessment, this process technology alone can save 20% of the company's manufacturing costs.
It is reported that the integrated die-casting technology has been applied on a large scale by Tesla. In September 2020, Tesla mass-produced the technology in the rear floor of Model Y; in May 2021, Tesla’s front cabin assembly was successfully developed, Applied to Model Y models in October. According to Tesla's first-quarter earnings conference call, future Cybertruck models will also use this technology on the rear floor.
With Tesla's demonstration and remarkable results, many new energy car companies are actively following up on this technology. Domestic car companies such as Weilai, Ideal, and Xiaopeng have all planned to deploy this technology. Mercedes-Benz, Ford, Overseas car companies such as Volkswagen and Volvo have also planned this process, which has become an industry trend.
Take the lead in the layout of enterprises and hope to enjoy industry dividends
As a technology that is maturing and showing scale effects, integrated die casting has received extensive attention. In addition to car companies, OEMs, die-casting machine equipment factories, mold factories, material factories, and aluminum die-casting companies are also vigorously deploying integrated die-casting technology.
GDWC is a supplier of aluminum alloy die-casting parts. Its products are mainly used in engine systems, transmission systems, chassis systems, braking systems, and body structural parts of mid-to-high-end automobiles.
The customers in cluding:BOSCH, BorgWarner, ZF TRW, WABCO, VALEO, GETRAG, JATCO,Mercedes-Benz, Ford,Volkswagen and Volvo…
In recent years, new energy, structural parts and internationalization have opened up room for growth. The company has supplied aluminum alloy body structural parts for Tesla and Mercedes-Benz in batches, and has a first-mover advantage in the lightweight of new energy vehicles and body structural parts.
