The overall die-casting cost is low, but the after-sales maintenance cost is high, and the safety factor is not reduced, because Tesla has a good safety braking system. Different from the stamping technology adopted by traditional manufacturers, Tesla adopts die casting technology. Through one-time die casting technology, the production cost of Tesla automobile can be reduced by more than 20%. According to statistics, in Tesla's Shanghai factory, a Tesla Model Y can be rolled off the assembly line every two minutes, and the die casting process can be completed within 80 seconds, and the die casting machine can complete at least 40 castings per hour. The traditional stamping process takes two hours to complete the assembly of parts. So there is no doubt that the die casting process has improved the efficiency of Tesla factory.

In terms of other costs, the die casting process also has great advantages. For example, the traditional process requires more machines and molds to complete the production and processing of multiple parts, and the labor and machine costs are high. However, after adopting the integrated die casting machine, the factory can only save 30% of the floor space, and the number of workers can be reduced to one tenth. However, the die casting process also has a big disadvantage, that is, the maintenance cost. When the stamping car is damaged, only one part needs to be replaced, while the die-casting car may need to replace a larger part, so the later maintenance cost is not low.

As for the safety factor, there is no data showing that the quality of die-casting body is worse than that of stamping body, and the safety factor of Tesla car has not been significantly reduced in the crash test. Volkswagen's safety concerns are mainly about its battery, not the die-cast body.

It is understood that Tesla CEO Elon? Musk said in the earnings conference call? We have basically completed the engineering design of Cybertruck pickup truck. We don't stop at the design stage, and the design part has been completed. We will soon order equipment for the production of Cybertruck pickup trucks.

We will use larger equipment independently developed by Tesla to produce the rear body of Cybertruck pickup truck, because obviously, it is bigger, the bucket is longer and the load will be great. Therefore, we will use 8000-ton die casting machine to cast the rear body, and we will use 6000-ton die casting machine to cast Y-shape ... 6000-ton die casting machine is the largest die casting equipment in the world. 8000 tons is much bigger than that. This model will be unparalleled. If we are lucky, we will be able to deliver some products before the end of this year, but I expect to achieve mass production in 2022. ?
