It’s one thing to launch a new mobile phone, tablet, electric scooter or smart refrigerator. And something very different is launching an electric vehicle like the Xiaomi SU7, which is the company’s most ambitious claim that we will see on sale in 2024.
And if Xiaomi SU7 has one thing going for it, it’s that it fits the company’s philosophy because, like its products, it offers a lot at a well-adjusted price. So how do you make an EV that is economically efficient and also has a distinctive appearance compared to its rivals? This is called HyperCasting.
Xiaomi HyperCasting
Xiaomi SU7 stands out with its design, 600 km autonomy, smart driving system with HyperOS operating system and maximum connectivity, as well as its production process using the so-called die-casting technology. HyperCasting, HE It allows the body to be produced with an innovative and efficient process.
The HyperCasting technology process works like this: 9,100 tonne integrated die casting machine is responsible for forming body parts in one goreduces the number of components, weight, costs and production times. This technology was first introduced by Tesla in Model Y, but Xiaomi improved it and raised the bar even furtherIncreasing the size, quality and strength of casting parts.
The core of Xiaomi’s HyperCasting pressure casting technology is a casting cluster that covers an area of 840 square meters and surrounds the pressure casting machine with more than 60 pieces of equipment. During spraying, temperature control and mold clamping, 9100 tons strong clamping force locks the mold firmly, In which the raw material of liquid aluminum alloy heated to 700 degrees is injected.
This is not only the formation of the die casting, but also the beginning of the grouping work, which allows you to combine 72 parts into a single part:
- 9 main processes such as inspection, cooling and cutting
- 433 industrial parameters fully connected
- 16 assembly processes precision automatic
A technology perfected by Xiaomi
Xiaomi is currently the only company in China to develop mass production of die-cast alloy materials on its own. as well as large-scale casting equipment systems. And Xiaomi SU7’s rear floor is an example of this, as it utilizes a large die-casting process and is 17% larger than Tesla’s, which requires a more powerful die-casting machine.
Therefore, Xiaomi customized and developed a huge integrated die casting machine with a clamping force of 9,100 tons and a weight of 718 tons, equivalent to the weight of four Boeing 747s.
Xiaomi titanium alloy and anti-collision design on SU7
There is another important component in this HyperCasting process, as the design and materials of the self-developed die casting assembly are essential. To this end, Xiaomi collaborated with the National Key Materials Laboratory, using the artificial intelligence simulation system with multi-material properties to select the most suitable alloy formula, taking into account strength, durability and stability, among 10.16 million formulas. Creating “Xiaomi titanium alloy”.
Not only that, Xiaomi is also creatively Anti-collision design in case of accident with SU7 vehicle. A smart design to quickly stabilize the vehicle according to the collision speed. For example, in this case medium and low speed collisionreplace the anti-collision beam and deformation zone of the car without the need to replace the rear floor, which guarantees economical maintenance.
