Integrated die casting in the field of new energy is expected to expand to body structural parts, new energy battery packs, subframes. 1) The defects of ordinary die casting are difficult to control, and in the early stage, they are generally used in the body of the shock absorber tower, ABC column joint, longitudinal beam joint and other joint parts. With the development of material upgrading, process optimization, intelligent large-scale equipment and the maturity of large-scale Die Casting Mold technology, the concept of advanced enterprises represented by Tesla are more and more trying to merge the parts of the body, from the stamping + welding process to an integrated die casting process. 2) Integrated die casting for body structural parts is not the main direction of integrated die casting, the process is now more used in chassis, battery pack and other parts of the body structure or smaller parts, the use of integrated die casting can improve strength, improve efficiency, reduce costs. 3) At present, some parts of new energy vehicles are most likely to be integrated die-cast. First, body structure parts, such as the case of the integrated die-cast body of Tesla Model Y; Second, the battery pack of new energy vehicles, the shape of the battery pack is relatively regular, the use of integrated die casting than ordinary die casting effect will be higher, the cost will be lower; The 2015 North American Automobile Industry Association report pointed out that the application of aluminum alloy in the subframe will be greatly improved in the next few years, and there is the possibility of integral die casting.
