The trend of integrated die casting is becoming clear as the demand for automotive lightweight incre

Fewer parts, lower assembly costs, in exchange for higher production efficiency, integrated die casting technology is regarded by a number of new energy automobile companies as a magic weapon to reduce costs and increase efficiency. Recently, Tesla has been rumored to have made a technological breakthrough in integrated die casting, and this technology has increasingly attracted the attention of the industry.

"Our next-generation platform has already introduced die-casting machines, and we expect to have integrated die-casting models on the market by next year." There are new power brand people told the Securities Times reporter that integrated die casting can better achieve lightweight body, the domestic OEM has long been eager to try, and the application range of integrated die casting is also constantly expanding.

In addition, with the gradual maturity of integrated die casting technology, the upstream and downstream industry chain team such as heat-treat-free material manufacturers and die casting mold manufacturers is also expanding. Recently, on the investor interactive platform, a number of listed companies responded to the progress of the project on automotive integration die casting. However, the landing of the new technology is not easy, some interviewees said that the automotive integration die casting process requirements are high, while there is also a dispute over higher maintenance costs for consumers.

The application range of integrated die casting is expanded

In the traditional automobile production program, dozens or hundreds of parts should be assembled and welded, and after adopting integrated die casting, the casting of specified parts can be achieved in one molding through die casting machine and mold.

Recently, Tesla was said to have made a technological breakthrough in integrated die casting. According to the report, with the above breakthrough, Tesla can die cast nearly all of the complex underbody parts of the electric car into a whole, instead of only about 400 parts. Securities Times reporters to Tesla China for confirmation, as of press time did not get more information.

In fact, as early as 2019, Tesla proposed the integrated die casting technology and applied it to the rear plate production of the Model Y the following year. At that time, the Tesla CEO said that the Tesla Model Y will use an integrated die-cast rear floor assembly, which can reduce the total weight of the vehicle by 30% and the manufacturing cost by 40%.

Since then, new forces have followed the layout of integrated die-casting technology. Compared with traditional fuel vehicles, due to the addition of battery packs, electric drive systems, etc., the demand for lightweight new energy vehicles with endurance requirements is particularly urgent. "The advantage of integrated die casting technology is that all the parts are pressed together, reducing the manufacturing cost, reducing the weight of the body, and simplifying the production line and process." Jiangxi New energy Technology Vocational College new energy vehicle technology research institute president Zhang Xiang told reporters.

"Many Oems are laying out integrated die casting, especially the new forces of car making, which basically have a layout." The new forces themselves have introduced relatively few large-scale equipment, and the transformation burden is small." Some industry insiders said that the new force car companies are more willing and motivated to promote the application of integrated die casting technology. In addition, traditional Oems, independent brands and international brand car companies are also accelerating their layout.

It is worth mentioning that previously, the market used integrated die casting process is mainly the rear plate, with the optimization of the process, the application of integrate
