The production of automobiles must pass The four major process, the so-called four major processes, simply, stamping, welding, coating, and general dressing.
Stamping is to stamp the steel plate into different components, such as four-door two covers, all of which are stamped. The welding is to connect these components to the welding. The painting is spraying paint coating. The assembly is equipped in assembly, various configurations, tires, glass, etc. Finally, the line is completed, a car will produce it.
These four major process flows are already very mature, and each automotive manufacturer is in use. More advanced automotive factories and general factories are nothing more than, who uses more automation robots in the factory, who is more secure.
So, this is why Li Bin, which is a great car, has said that the manufacturing process of Jianghuai Auto has not lost to Porsche. In fact, its accurate meaning is that the process flow of the car is almost the same, as long as it is The degree of automation is improved, and if the material is further improved, then Jianghuai’s factory can also make a car comparable to the best quality.
What does it mean by TESLo-opening a monomer-cast car body?
Recently Tesla has developed a new car craft called a monomer-cast car body, this structure is very complicated, weighing 130 kg. It is molded from a 6000-ton casting machine. So recently German die-casting experts share the die castings of Tesla Model Y models on social networks.
This is not the first car parts that Tesla first uses monomers. Last year Tesla implemented Model Y, the entire body of the entire body, one part of the body, will M70 components on Odel 3 are integrated into two components on Model Y.
And Teslavan is that the entire white car will be manufactured in the future, the maximum effect of doing this is to turn stamping and welding two process flows into one, then from cost It will definitely be able to decrease, the cost of manufacturing.
But Tesla’s way, did you think of these other car brands?
It is definitely not that in fact, there are very many manufacturing processes of the aluminum alloy body on the Tesla car. Cadillac, BMW, Audi and other models also use the cast parts of aluminum alloy. Just do not have such a large amount of aluminum alloy cargo castings like Tesla.
Other automakers have been summed up through automotive production and manufacturing in the past 100 years, and a set of processes and experiences belonging to themselves. But Tesla is not allowed to follow these traditional automakers and want to subvert them.
What are the risks of a monomer die casting vehicle?
What are the shortcomings of Tesla’s monomer die-casting vehicles? In fact, the birth of anything is beneficial. Many people see that Tesla uses the monomer pressure body parts, first thought is that the future maintenance cost will be higher, the original parts are assembled, where to hit, and it can be changed. So now it is now replaced with a integrated structure, it is not easy to repair.
There is also some other problems in addition to this. For example, the die-casting process is difficult to avoid the existence of bubbles in the product. For a simple example, for the car rim, there is a compression cast wheel and forging a rim, the die-cast wheel is much cheaper than the forging riser, which is that there is bubbles inside the product, and there is no way from the appearance. come out. These bubbles will affect the intensity in the use of products.

In addition, the monomer die-casting vehicle body is also more test components, which requires a lot of preparations in the early stage. Because if it is a traditional car, there may be no problem in the development phase of the product, and when the vehicle road test is found, some body problems have been discovered after delivery to the user’s hand, after using a large number of users. Then traditional automakers can investigate and optimize according to different components. In the next year, it is not possible to fix the body when the annual relevance is changed, and the cost is not high.
If the monomer die-cast body is used, if this body is not designed very perfect, when a large amount of delivery is delivered to the user, the user will appear after use, so for the manufacturer If you want to modify it, you can only re-modify the design, then re-modify the mold, so the cost is too much.
Of course, the squeezing machine of Tesla Factory Of course, the monomer die-casting vehicle body is used for aluminum alloy materials. It is also very high for use in the use of die casting machines. Compared to the current four-priced process flow. In this way, the cost of pre-input is higher. But Tesla is a public and Toyota in pure electric car brands. Therefore, if a large number of monomer-cast components, it is possible to reduce costs for Tesla.
In addition, I saw that there are still many netizens who are ridiculed. It is very interesting to say this manufacturer. It feels very advanced, but even the car. The basic process of manufacturing is particularly poor. For example, the seam of the body is not very uniform. For example, there are some licensed frames, including some cars, LOGOs, are bare. The propaganda is very good, but the actual performance is quite bad.
