How to tell if the painted body is flat? How to deal with sheet metal?

Observe the painted body from different angles to see if it is different from the original painting. If the difference is significant, sheet metal is applied and then painted.

It's best to look at him there, and you can see it by comparing it with the original paint.

It must be painted in its entirety. Sheet metal painting is a kind of car repair technology, such as the car body shell is hit by a pit, you can restore it to its original state through sheet metal, and then by spraying special paint, the deformed car metal surface can be restored to the same bright as other intact places. There are still some defects that cannot be repaired by sheet metal work after the car body has been corrected by sheet metal, and even if it is replaced with new parts, there will be imperfections.

In order to be more perfect and refined, it is necessary to use the sculpture process to make up for the defects, after the car is damaged by deformation and other reasons, its flatness, wheel angles and lines, each part needs to be filled with scraping ash to grind out. Any body skin of a car is stamped from a mold, and repairing the body skin is the same as repairing a mold.

Hello, this is generally speaking, after the car sheet metal is repainted, the whole needs to be repainted.

Sheet metal painting is a kind of car repair technology, that is, the deformed part of the metal shell of the car is repaired, such as the body shell is hit by a pit, you can restore it to its original state through sheet metal, and then through spraying special paint, the deformed metal surface of the car is restored to the same as other intact places, as bright as ever.

After the car body is corrected by sheet metal, there are some defects that can not be made up for by sheet metal work, even if it is replaced with new parts, there will be imperfections, in order to achieve more perfect precision, it is necessary to make up for the defects with the process of sculpture, after the car is damaged by deformation and other reasons, its flatness, wheel angle and lines, each part needs to be scraped to fill the grinding out, with this formula: scraping ash = restoring the body skin = mold product = mold processing program, Any body skin of the car is stamped by the mold, we repair the body skin is the same as repairing the mold, so we scrape the ash and shape the process to be coherent with the mold processing, which is the work that the general painter can not do, many painters who have been working for many years will sigh a sentence "It is easy to spray a car, it is difficult to do a piece of ash, and it is difficult to grind a ball of ash in ten years" People who say this may really know what is called car spraying.

S shop spray paint requires the original car paint to be sanded off until the steel plate layer is exposed, and then sprayed with three paint layers, namely the middle coat, the color paint layer, and the clear coat layer.

The biggest difference from the original paint is that there is no electrophoretic layer. The so-called electrophoresis layer is that the frame needs to be soaked in the paint pool, and then the paint pool is energized and electrolyzed, so that the paint can be tightly attached to the steel frame of the car body, effectively preventing rust.

The painting process of S shops and repair shops can be roughly divided into cleaning and polishing, priming (intermediate coating), painting, baking and polishing.

1.Polishing the surface of the body sheet metal paint. Generally, after scratching and collision, it is necessary to repair the sheet metal to the basic shape first, and then use professional painting and polishing tools to polish off the original paint to expose the metal plate.

2. "Putty scraping flat". Scraping putty mainly ensures the smoothness of the paint surface and makes up for the depression of the paint surface. Generally, it takes three times, depending on the effect after painting.

3.Use the pigment mixer to scan the pigment and then fine-tune it manually. Due to the different lifespans of different vehicles, the paint changes slightly. Technicians need to compare paint templates and body colors on the spot. Fine-tuning is a test of the master's experience, and it is also the most critical.

4.Then spray paint. The main types of spray paint are ordinary paint, metallic paint and pearlescent paint. Different types and brands of paint** are also different.

Millions of car purchase subsidies.

Many car owners have questions after the body is painted. Automotive sheet metal.

What is the difference between painting and the original car?

In fact, there is a difference between automobile sheet metal painting and original car painting.

The original car factory painting environment is a dust-free environment, and the painting is an overall coating, with uniform paint surface and uniform thickness.

In post-maintenance, painting is applied locally. Compared with the original paint, it will be uneven and different from the thickness of the original paint.

In fact, now the color of the original car can be basically restored with computer paint mixing technology, which is difficult to detect with the naked eye.

However, due to differences in coating thickness, coating environment, coating temperature, etc., color deviation may occur.

In addition, the bottom layer before the topcoat is sprayed will also have a certain effect on the paint color. That's why we recommend repainting the entire car instead of repainting it after a scratch.

The working form and cross-linking temperature of the repaired paint are very different from the original paint. Compared with the original paint, the restored paint is more prone to oxidation and discoloration, but the initial effect can last for about two years after the repair. Car owners who have experience in painting know that in fact, painting in a regular painting place can not see obvious color difference with the naked eye in the later stage.

Moreover, the experienced old painting engineer has taken into account the external factors, baking paint and other factors when mixing the paint, which basically ensures that the color difference is not large and does not affect the appearance at all, so the owner does not have to worry too much about the color difference of the painting, and can find a regular painting shop.

The difference between the sheet metal painting and the original car is as follows:

The painting environment of the original car is in a dust-free environment, and the painting is the whole painting, the paint surface is uniform, and the thickness is the same. The painting during the later maintenance is sprayed locally, which will be uneven compared with the paint of the original car, and the thickness of the paint surface of the original car will be different. In fact, the use of computer paint mixing technology can basically restore the color of the original car, which is difficult to detect with the naked eye.

However, due to the difference in painting thickness, painting environment, painting temperature, etc., the color will be deviated.

In addition, the bottom layer before spraying the topcoat will also have a certain effect on the paint color. That's why it's advisable to repaint the entire piece after scratching instead of touch-ups. The repair paint is more oxidized and discolored than the original paint, but the initial effect can be maintained for about two years after repair.

There must be a slight difference between the car painting and the original factory, but the difference is generally not large. As long as the painting master has good skills, it will not be seen without careful study.

It can be said that the original car paint is the only original parts that can not be bought on the car, the repair car paint and the original car paint work form and, the cross-linking temperature is very different, the repair car paint is easier to oxidize than the original car paint, easy to discolor, but the initial effect can be maintained for about two years after repair, much better than not doing treatment.

The repair of the car paint and the original car paint of the form of operation, the cross-linking temperature is very different, the repair of the paint than the original car paint is more prone to oxidation, easy to discoloration, but the initial effect after the repair can be maintained for about two years, than not to do the treatment is much better.

There are differences, the first is that the 4S store is much higher than the store. Second, the construction period of 4S shop is much longer. Thirdly, the paint materials used in the 4S store are better than the outside, and the color difference is smaller, and that's all. In short, each has its own advantages and disadvantages.

There is no difference, it mainly depends on the craftsmanship of the workers.

The update is more beautiful and looks better.

It's better to go to a 4S store, and the craftsmanship and materials used in the small store may be worse.

There are more or less color differences.

Spraying is a highly technical and demanding job. In order to achieve a smooth, uniform thickness and mirror-like surface of the coating after spraying, in addition to the high requirements for the variety and quality of the refinish paint and the underlying foundation of the coated object, the correct operation method and spraying technology and experience are also very important. China's car paint in use is still based on solid color paint, pure color paint is not too demanding on spraying requirements, but with the continuous development of the coating industry, the variety of automobile paint continues to increase, and the grade of automobile paint is getting higher and higher.

Sheet metal is actually very knowledgeable, basic car modification, made of chimneys, dustpans, air conditioning pipes, flange shelves, etc., many of which are classified as sheet metal, automobile sheet metal is mainly used for disassembly and assembly (not involving the engine), basically all sheet metal work, surface repair, girder correction, electric welding (electric welding machine, oxygen protection welding), gas welding, argon arc welding, instruments used, sheet metal repair machine, oxygen protection welder, girder calibrator, ground gossip, etc., the factory equipment with good conditions is all over the place, and the work is also happy, and some second-class auto repair plants It's pitiful, there is no equipment, and the time to work is doubled to complete In the field of car repair, the sheet metal is the most, first of all, when you repair, you have to flatten it, otherwise the painter doesn't want to scrape the putty, the girder is not well corrected, and the machine repair is found to be resonant, and the engine is installed to produce resonance, and the master leads the door to practice, and it depends on the individual, and he is diligent and flexible, and the brain is flexible, and you will be the master in the future, I am in Beijing, and now the sheet metal master gets about 4,000 in the second class, and the 4S shop is profitable, and the auto repair factory gets a commission, and the more you do, and you get more believe in yourself, I am also sheet metal, and it is fun to go to work every day, and I wish you success.

Car painting is a kind of car beauty method, which refers to the effect of giving a layer of paint on the surface of the car to protect the car.

Automobile primer, also known as anti-rust primer, is the paint for the primer, which is generally directly applied to the surface of the object or applied to the surface of putty. Its function is to prevent oxidation and corrosion of the metal surface, and enhance the adhesion of the metal surface to putty or intermediate coat and topcoat.

So the simple summary is that if your body has cosmetic damage and deformation, you need automotive sheet metal. If you simply want to enhance the wear and corrosion resistance of the car, you can choose painting.

Many car owners will have questions after the body is painted. What is the difference between a car sheet metal painting and the original car?

In fact, there is a difference between car sheet metal painting and original car painting.

The coating environment of the original car factory is a dust-free environment, and the coating is an overall coating, with uniform paint surface and consistent thickness.

The paint in the later maintenance is biased, which will be uneven than the paint surface of the original car, and the paint thickness of the original car will also be different.

In fact, now the computer paint mixing technology can basically restore the color of the original car, which is difficult to detect with the naked eye.

However, differences in paint thickness, paint environment, paint temperature, etc. This can lead to color deviations, and the undercoat before spraying can also have an impact on the paint color. This is also why, after the car was scratched, we suggested that we repaint the whole car instead of touching it up.

The repaired paint is very different from the original paint in terms of how it operates and the crosslinking temperature. The repaired paint is more susceptible to oxidation and discoloration than the original paint, but the initial effect can be maintained for about two years after repair.

Car owners with experience in spraying paint know that in fact, spraying paint in a regular painting place will not be obvious to the naked eye in the later stage. And the experienced old painting engineer has taken into account the outside world, baking paint and other factors. When painting, it is basically guaranteed that the color difference is not large, and it does not affect the appearance at all.

Therefore, the owner is not too worried about the color difference of the spray paint, and only needs to find a regular paint shop.
