Is the van in China getting thinner and thinner? The main points of the article are:
If a foreign automobile company wants to use thinner steel plates in the China market, it must develop two sets of molds at the beginning of design. One of them can only be used in China market. I don't think I have heard of such a thing.
What's more, the current China auto market has forced major auto giants to launch the latest models one after another. If the dies are painstakingly redeveloped in order to obtain the benefits brought by the thinning of steel plates, the new cars may become yesterday's flowers when they can be introduced to China for production.
The result of the discussion may be unexpected. That is: it is not worthwhile to make the station wagon thin, and it is impossible for any stupid manufacturer to do so.
Many netizens have their own opinions on this issue. The following are the views of some representative netizens to share with you:
Viewpoint 1: Netizens pass by.
In fact, I don't think the steel plate is thin, because if the steel plate is thin, even the welding process will have to be changed, and even the wiring harness/glass/skylight installed on the steel plate will have to be redesigned in size and connection mode. This is really a big move. No factory should be willing to do this.

It is possible to have a thin station wagon, because although the appearance of the same model car is the same, it is impossible to use the same set of molds at the same time because of the different production locations. Guangzhou Honda's car shell can't be produced in the United States, so we can only reprocess a set of molds and produce them in China. One exception is the assembly of parts. This mode of production also exists in other countries. It seems that Japanese manufacturers haven't done this yet, because the labor cost in China is low, and the price of common parts produced in China is much lower than that produced abroad, which is not in the interest of Japanese manufacturers.

The die gap is designed with plate thickness difference. The tolerance of 0.8 steel plate is about 0.25, which can be completely changed to 0.8 to 0.6 or even 0.5, and the die hardly needs to be changed too much.
It is unlikely that the station wagon will become thinner. However, it is absolutely possible to use type of steels inconsistently. What's more, everyone knows that the quality of German steel is first-class. The composition and thickness of the material will affect the quality.
Linda concluded: One of the most important reasons for the mystery of whether China's wagons have become thinner is that the public can't get correct data from the government. Therefore, it is hoped that relevant departments can attach importance to this issue, conduct some relevant tests as soon as possible, publish relevant data, and give domestic riders the right to know.
Let's go on to discuss a very important issue. namely
Does the thickness of the station wagon affect the safety of the car?
For this question, let's take a look at the opinions of netizens:
Viewpoint 1: Netizen "Genghis Khan"
Frankly speaking, thin wagons have an impact on safety, but the strength of steel and the composition of materials are more important. No matter how the car hits, the girder will not break, because the girder is composed of three layers, both inside and outside.
Viewpoint 2: Netizens "discover"
In fact, when a car collides, it really needs the car body to absorb the collision energy to reduce the damage to the occupants, but the thinner iron sheet and the poor driver will be more deformed in the event of collision, so that the occupants in the car will not be killed and squeezed! Volvo is safe because it can absorb collision energy evenly and effectively in the event of a car accident. I think the fundamental problem is driving! When the driver can't bear the torque caused by collision or rollover, the break is inevitable!
Does the thickness of steel plate affect safety? The answer is not only yes, but also beyond your imagination: 20% steel sheet does not mean that the safety is reduced by 20% or the loss is increased by 20%, but it means that your energy absorption zone works before your opponent and will work until it is resisted by something harder (maybe your cockpit) and bear almost all the collision deformation losses!

The thickness of the truck is not important. Some cars are poor in quality because the steel is not hard enough and inferior steel is used. Inferior steel has poor rigidity and toughness, and of course its anti-collision ability is also poor. For example, an iron pot for cooking can't be used as a pressure cooker.

In fact, the thinning of station wagons is a major trend of modern automobile design, not only Japanese cars, but also many European and American cars, such as a new generation of Mercedes-Benz, Ferrari, Audi, Porsche and other famous cars. The thinning of the station wagon makes the appearance of the car lighter and more fashionable, which is more in line with the aesthetics of modern people.

In fact, the most important concept is that the factors that determine the overall safety of modern cars are active safety and passive safety, in which passive safety simply refers to the safety of vehicles after a collision. The thickness of the station wagon is not the decisive factor of the car's firmness, but the real decisive factor is the car's frame structure, that is to say, the firmness and design level of the frame are the factors that best reflect whether the car is safe in the event of a collision.
There is a considerable gap in strength and toughness between China steel plate and Japanese steel plate with the same thickness. In fact, the fundamental reason why the quality of all products in Japan is different from that of foreign countries is that the raw materials used are different and the manufacturing process is different.
To make an inappropriate analogy, it seems that all houses now adopt frame structures. When an earthquake occurs, the decisive factor that determines whether a house collapses is not the thickness of the wall between frames, but the quality and design of the frames. The wall has a great influence on daily life, such as whether the sound insulation is good, whether it will collapse when a small impact occurs, whether it will loosen after a long time, and so on. For details, please refer to the article "Is Fit Safe? What is the effect of thin wagons? 》
Linda concluded:
Judging from the current situation, the discussion about the thickness of trucks is worried about the safety performance of cars, while the netizens' doubts about the thinning of trucks in China are actually worried about the quality of cars in China. Driving safety is not only related to the happiness of drivers, but also to the happiness of thousands of drivers' families in Qian Qian.
Although there are many various forms of automobile collision detection centers in China, the public has no way to obtain relevant evidence. China riders are also very concerned about the thickness, model, toughness and strength of steel plates used in automobile manufacturing.
Cherish life, everyone is responsible! It is hoped that the relevant departments can regularly publish relevant information from the perspective of caring for life, so as to provide reference for motorists to buy cars.
Actually, the steel plate doesn't have to be very thick. Driving costs oil.
