Xiaomi's self-developed large die-casting technology has raised questions in the automotive industry, and some netizens claim that Xiaomi's die-casting machine is accumulated through purchase, not really self-developed. In this regard, professionals gave a detailed answer to Xiaomi's die-casting technology and emphasized the advantages of self-development. In fact, Xiaomi's large-scale die-casting technology is indeed independently developed, and the official statement that it is called a "full-stack self-developed die-casting cluster" is in line with the facts.
First of all, in the whole process of large die casting, there are three parts: upstream equipment, die casting production line and die casting, which correspond to the overall flow of equipment, process and result. In terms of upstream equipment, all car companies achieve production by purchasing die-casting machines, which is similar to the purchase of lithography machines in the chip manufacturing process. However, Xiaomi and other car companies have taken a completely different path in purchasing die-casting machines. Xiaomi is not only buying die casting machines, but more importantly, they have the ability to independently design and operate die casting production lines, and are able to produce die casting parts themselves. Other car companies adopt a factory-in-factory model, and the die-casting machine, die-casting factory and die-casting production line are managed by the first company. This shows that Xiaomi has truly achieved a "full-stack self-developed die-casting cluster", which can be fully responsible for the design and acceptance to the production process, which is the key to Xiaomi's ability to better control quality.
Secondly, the analogy of Xiaomi's large die-casting technology with mobile phone chips can also help understand this problem. Although Apple, Huawei and other companies have independently developed mobile phone chips, they do not have their own lithography machines to produce these chips, and even the cores and industrial software designed for these chips are not their own. Again, the final packaging equipment is not its own. Obviously, this does not negate their own research results. Similarly, Xiaomi's self-developed large die-casting technology is also optimized and innovated on the basis of existing equipment, which is not contradictory to the situation that other car companies do not have their own die-casting production lines.
There is a motive behind Xiaomi's questionable die-casting technology, which is attacked and confused. As an important support for Xiaomi's entry into the automotive industry, large die-casting technology may reduce Xiaomi's competitiveness in the industry once the public doubts it. Since Xiaomi entered the car track and moved some people's cakes, some people deliberately confused the equipment and production process, trying to create a gap between Xiaomi and other car companies. However, attacking others does not improve oneself, and such behavior can also have a negative impact on the development of China's automotive industry.
From the above discussion, it can be seen that Xiaomi's large die-casting technology is indeed independently developed, which is obviously different from the practices of other car companies. Xiaomi has full control over design, operation and production, which allows them to better control quality and improve competitiveness. However, questioning and attacking do not change the facts, they only damage the reputation and development of the industry.
In my opinion, there are some rivalries and conflicts of interest hidden behind the questioning of Xiaomi's large die-casting technology. When a new enterprise enters an industry and achieves certain achievements, it is bound to cause attacks and doubts from other competitors. This competition is inevitable, but the key is to compete in a fair and objective manner, not through attacks and misdirection. We should look at Xiaomi's scientific and technological innovation and independent research and development from an objective perspective, encourage and support more enterprises to actively participate in the development of China's automotive industry, and jointly promote the progress and innovation of the entire industry.
