How is the Hyper Die-Casting introduced by Mr. Lei and Shu Qi in the livestream produced?
Integrated hyper die-casting technology was first mass-produced by Tesla on the Model Y. Through giant high-tonnage die-casting machines, previously scattered body parts are die-cast into a single piece. Compared to traditional processes, it has multiple advantages such as high production efficiency and strong, reliable parts. Xiaomi EV is one of the few automakers globally that simultaneously masters two core technologies: self-developed mass-production die-casting alloy materials and a self-developed hyper die-casting equipment cluster system.
The Xiaomi EV rear floor produced through Xiaomi Hyper Die-Casting technology integrates what were originally 72 parts into one, reducing welding points by about 840, cutting weight by 17%, lowering interior road noise by 2dB, and reducing production man-hours by 45%. The design life of the integrated rear floor is more than 10 times that of a traditional rear floor, capable of achieving a service life of over 2 million kilometers.
The uniqueness of Xiaomi Hyper Die-Casting lies in the fact that it is not just about introducing a single die-casting machine, but building a hyper die-casting factory and completing full-stack in-house development of almost every link in the die-casting industry chain. Adhering to high quality and in-house development is not only the ultimate pursuit of quality but also the determination to build good cars earnestly.
