Recently, at the 2022 NIO Partner Day, NIO CEO Li Bin said that the original planned delivery of ET7 in July was a step up from more than 4,000 units in June, but the shortage of castings led to the production of thousands less. trolley. At present, it takes several months for ET7 to order a car and pick up a car. Li Bin shouted on the spot, asking suppliers to withstand the pressure of delivery.
It is understood that NIO ET7 is the first model of NIO’s second-generation platform and will use a new heat-free material. Compared with general aluminum alloy die castings, which require solid solution and aging heat treatment to meet the strength, durability, and impact resistance required for body performance, the new heat-free material avoids the dimensional deformation and impact caused by traditional die castings during heat treatment. Surface defects make large body die-casting possible. Aluminum alloy die castings made of this heat-free material can not only improve the quality of large die castings, optimize production efficiency, increase production capacity, but also greatly reduce energy consumption and carbon emissions in the manufacturing process.
