On September 27, SMM saw at Tesla's super factory in Lingang, Pudong, Shanghai, that the rear bottom plate assembly system of Tesla Model Y produced here had successfully adopted integrated die-casting technology to achieve rapid die-casting. According to Cui Hailun, manager of structure and thermal management system of Tesla Shanghai Co., Ltd., on Tesla Model Y integrated die-casting rear bottom plate model, the original parts were integrated into one part, and the production efficiency was greatly improved. Compared with the traditional method, the body system saves more than 10% of weight. In addition, there are also very obvious cost advantages. Benefiting from optimized structural design and material recycling, the cost of the rear bottom plate assembly system of the car has been reduced by 40% after adopting the integrated die-casting method.
