Compared with joint venture cars, why domestic cars are more prone to rust

In daily life, why do you feel that domestic cars are rustier than joint venture cars? Not only the quality, in recent years, the development speed of domestic brands is very fast, many domestic cars are good space and configuration, but the control of the product is not smooth, that is to say, the quality of domestic cars is not good is not closed properly, so domestic cars are easy to rust. Compared with domestic cars, joint venture cars are not easy to rust?

This is because many joint venture cars have strict standards for quality control and materials, using ultra-high hot-stamping steel plates and anti-corrosion and anti-rust materials, so compared with domestic cars, some joint venture cars have better anti-rust performance.

Domestic more important cars are equipped with sufficient anti-rust preparations, but they greatly ignore the anti-rust of small parts such as screws and leftovers, unlike European and American car brands that have done extremely careful anti-rust work at the joint.

In terms of automobile frame materials, most of China's domestic operators do have the problem of cutting corners when manufacturing automobiles, in contrast, some conscientious joint venture cars are indeed made of better materials in terms of structure, galvanized steel plate, tinned ferroalloy and ultra-high hot-stamping steel plates, these are more stringent materials, but the domestic manufacturing of automobile materials is relatively cheap, the cost is relatively low, the anti-corrosion performance is very poor, the quality is not guaranteed, and, Most of the domestic cars used in the spraying process has not reached the international standards of joint venture cars and imported cars, which is also the reason why domestic vehicles are more difficult to export, most of China's automobile manufacturing can not be compared with joint venture car companies, this reason is also the main reason for the serious corrosion.

This is because the quality of domestic cars cannot be trusted, and there is no protective device on the surface, so it will rust.

Because there are certain shortcomings of domestic cars, these shortcomings are what the researchers have been working on, and they have devoted all their time to this matter.

Because the materials used in domestic cars are different from those used in other brand cars, they are more prone to rust.

Because the production in this area is not delicate enough, there are some problems that have not yet been overcome, so it is more likely to rust, so it has always been a headache.

It is very likely that the material used in domestic cars is more iron, so it is sometimes easy to rust.

Most likely, it is the reason for the material. These materials are prone to rust. Paint is also a big issue.

Hello, dear, domestic cars are seriously rusted ranking: the first is BYD F3, BYD has developed very fast in China, especially in the past two years in the field of new energy vehicles, all the way to the development can be said to be smooth, many of its models have also been exported to foreign countries, and have gained a large number of fans, but BYD F3 The performance of this car is not satisfactory, many owners have responded that the rust of this car is very serious, and the new car will rust after about a year of use, In particular, the chassis of the car is respectful, and if it encounters rainy weather, the situation will be more serious, and when driving, I am worried that it will fall apart. The second is Changan Yuexiang, looking at the domestic automobile market, among the domestic cars, the reputation of Changan Automobile is already very high, and it is also very competitive in the market, when it comes to this brand, the first thing that comes to everyone's mind is the cost performance, it is precisely because of the high cost performance, so it will be loved by many consumers, but Changan Yuexiang is also an exception, although the performance in terms of appearance and configuration is good, but the rust problem of this car has not been properly solved, according to many car ownersThe doors of this car are the most prone to rust, and the interior is also prone to rust over time.

The last one is JAC Tongyue, when it comes to JAC, everyone is no stranger to JAC, JAC's popularity in China is even higher than Chang'an, and the reputation of the pants in the market is also good, but since the launch of the Tongyue car, many car owners have complained that the quality of this car is seriously problematic.

Domestic cars are more abundant than joint venture cars in terms of vehicle configuration, and more complete models can be bought under the same conditions. However, the gap between domestic cars and joint venture cars in some technical aspects is very obvious, especially anti-rust technology. Take Japanese joint venture cars as an example, Japan, as an island nation, faces strong corrosiveness in coastal areas.

If the anti-rust technology is not good, the vehicle will have a large area of rust after a few years. Anti-rust technology is very basic for Japanese cars. One might think that the anti-rust effect of a car depends on aspects such as the base material and processing technology.

But in fact, it's not that simple. Sometimes, rust can start with a small screw. If stainless steel bolts and nuts are used on vehicles made mainly of iron, they can also easily rust and electrolytic corrosion.

There is a potential difference between stainless steel and iron, so the iron is corroded into fragments, which is known as electrolytic corrosion. The use of stainless steel bolts and nuts is not good for rust prevention, so it is best to choose a high-quality coating to prevent corrosion. It is also very important in the post-processing of the vehicle, such as the anti-rust coating on the chassis and the design of the water outlet.

However, these measures will increase the cost of building a car, and it is also a significant expense for production models. As a result, some manufacturers may not be conscientious in implementing these processes, which is also known as "cutting corners". Compared with domestic joint venture cars, domestic cars still have deficiencies in detail processing, as an example near the former suspension, you can see a sound-absorbing cotton quilt fixed, but basically no anti-corrosion performance; In contrast, near the front suspension, you can see the exhaust holes and waterproof plastic panels, and the bezels are also sprayed with anti-corrosion coatings.

Therefore, the anti-rust technology is reflected in all aspects, and if it can be improved in the anti-corrosion of the vehicle, then it is certainly not a simple project.

Because some domestic cars do not have the processing of steel in place in order to save costs, some domestic cars love to rust.

I think it's because it's not well made, so it causes the metal inside to oxidize.

Because of the problems existing in domestic car enterprises, the car-making technology is not very mature, and there will always be problems in process materials.

In addition to domestic cars, joint venture cars also have rust, and the design of the car itself, the use environment of the car, and the manufacturer's production may be the cause of rust. Some cars themselves are poorly used, the cost of paint and sheet metal materials is low, workmanship and materials are one of the standards to measure the worst of a car, but some car manufacturers, often for higher profits and the need to compete with other manufacturers, save costs, of course, in order to sell the car will also be very tempting, the use of ordinary sheet metal, resulting in the car that can be guaranteed for 6-7 years without serious rust, one or two years or even shorter on the appearance of rust, affecting driving safety.

There are also complete structural design that are not considered in the design, and there are sharp corners or dead angles in the sheet metal, which leads to insufficient electrophoresis of the automobile body, or the process design is not fully considered, so that the sheet metal is not fully integrated in the process of electrophoresis and wax injection.

Now many car friends often complain, just after a year of rust, and even some netizens appealed, resolutely do not buy domestic cars in the future, this is what I just said, this is unfair, for example, some cars only care about sales, quick success, made low-grade products, you are greedy for cheap buying, and then something goes wrong, you are scolding domestic cars are not good, so of course it is unfair to other domestic brands, the truth of a penny for a penny, now 3-year-old children also understand.

Therefore, when buying a car, it is very important to look at word of mouth, don't be greedy for a temporary cheapness, buy products that you regret, and now basically replace them with galvanized steel sheets that are more resistant to rust. The connection method also minimizes the accumulation of liquids and avoids the connection of dissimilar metals. In addition to these, there are methods such as spraying car paint, cavity wax injection, glue spraying and other methods for the electrophoresis treatment of the car body, such a process will definitely increase in terms of cost and materials, and compared with those with low cost and low quality, the best sold will naturally increase, but I think that if you really buy a good product, it is acceptable to increase appropriately, and it is better than buying back a trouble, what is unacceptable is that some car companies are not aware at all, everything is good when there is no problem, and they say that they are a joint venture brand when they are technical, When comparing the plot, he said that he was his own brand, and something went wrong:

Tens of thousands of dollars, what else do you ask for, it's not good, it's not good to buy Mercedes-Benz BMW, such a car company, sales will eventually become zero.

In fact, I feel that no matter what brand of car. You don't care for it. Rust is normal. Bumped. It should be fixed in time. Touch-ups. Otherwise, the metal material will rust in a few days. After a long time, it will be pierced.

Nowadays, the car manufacturing process is becoming more and more developed, and at the same time, the price of cars has been decreasing. Some people wonder why cars are getting better and better, but the price is lowering. In fact, everyone's question is whether car companies are actually cutting corners in places that car owners can't see?

For this question, I personally think it is very possible. Because in recent years, some rusty cars have indeed been found, and they are all domestic cars. So, will all domestic cars rust?

Not really. Most domestic cars do not rust, such as Geely cars. However, this does not mean that there are no rusty cars.

Here are a few examples of cars that rust easily. Below, let's take a closer look.

First, Chang'an Yidong

Changan Yidong can be described as a more popular model in domestic cars, this car is characterized by rich configurations, the shape is also very young and fashionable, and the power realization is also very good, but its price is not high. However, although it is a Changan Automobile, some owners have reported that it rusts after less than a year of driving, which shows that the quality is really poor.

II. Arrizo 5

Chery can't escape the fate of rust. Arrizo 5 is a car that Chery focuses on, this car is ideal in terms of both appearance and interior, but some car enthusiasts have reported that this car has rust in many places, such as rust in many places such as the engine compartment, doors and body.

3. Changan CS75

It is also Changan Automobile, and Changan CS75 is also a very popular car, and it is also a popular SUVAt that time, its sales were very hot, and it was the star model of Changan Automobile. However, the biggest failure of this car is the rust problemYou know, the price of this car is more than 100,000 yuan. Cars with such a high price also have rust problems, which has to make people question the quality of Changan automobiles.

The above models are the models that will rust, although the market performance was very good at the time, but because of the rust problem still disappointed many consumers.

Why many domestic self-owned brand cars are easy to rust, in fact, this is not a common problem of domestic cars, but a problem of individual enterprises. Even if it is a joint venture car company that started earlier and has relatively mature car manufacturing technology, rust is an inevitable problem.

Why does the car rust, is it caused by the process materials of the car company or the car owner's non-standard car washing environment?

In order to save the cost of car manufacturing, some car companies will choose materials with poor materials, and the cost of car paint and sheet metal materials is low, which is one of the reasons for rust.

Some domestic car companies do not do a good enough job in surface painting and anti-rust treatment, and the rust in the skin will affect the appearance, and over time, the large area will also affect other auto parts, resulting in abnormal noise. If the frame is rusty, it will affect safety and be a big problem. At present, according to my understanding, it is caused by the lack of rust prevention in the automobile factory, and the attention of domestic manufacturers in this regard is not very good.

Especially after six or seven years of car use, some car chassis are seriously rotten, and now this problem has not improved, I can't say, after all, the new generation of domestic cars that look good has not been used for so long.

Why are domestic cars more prone to rust? After doing it for so many years, can't even get a piece of iron to prevent rust?

Why do domestic cars often have rust problems? After so many years of joint venture, I can't even get a piece of iron.

The cost of steel plate and the application of electrophoresis technology are directly related to whether the material of the car itself is rusty. Not all domestic cars will rust, but the rusty domestic cars are in the lower end of the model. It is precisely because of the cost that the manufacturer will not invest too much resources in rust prevention treatment, and generally speaking, it can insist on 3 years without rust.

With the development of domestic cars, some of the more high-end domestic cars will not be rusty, but they are called A0-class models, and even A-class or even quasi-B-class domestic cars will still be rusty. According to the statistics of the car quality network, the rust probability of domestic cars is indeed much higher than that of joint venture cars, and the rust probability of low-end domestic cars is the highest.
