The repair cost of automotive sheet metal depends on the difficulty. Usually, sheet metal repair will be repainted. In general, the two are counted together. For ordinary cars, taking the door as an example, the charge for small sheet metal and painting is around 400 yuan.
Automotive sheet metal is a technical means of automobile repair, and automotive sheet metal repair refers to the repair of automobile body after collision, that is, all work except anti-corrosion and decorative spraying of automobile body.
Automotive sheet metal is a processing method of automobile maintenance, also called cold working. To put it bluntly, if the appearance of the car body is damaged and deformed, the sheet metal process is needed.
Automobile collision repair has developed from the initial "welding repair" to the secondary manufacturing and assembly of the car body. The repair of vehicles in collision accidents is no longer a simple automotive sheet metal knock, and the quality of repair can not be observed only by naked eyes.
Sheet metal operation process:
Disassembly of sheet metal parts: the sheet metal parts that hit the damaged parts of the vehicle are removed from the original body by cutting.
Damage confirmation: after cleaning the damaged part, confirm the damage degree, so as to establish the repair method.
Remove the old paint film: polish the original car paint on the damaged part until the iron plate layer is exposed.
Flattening of sheet metal parts: according to the damage degree of sheet metal parts, use the corresponding sheet metal tools to flatten the concave parts. The surface of sheet metal parts should be fine-tuned to obtain flatness.
Fire extinguishing treatment: through fire extinguishing treatment, the tensile and compressive stresses generated in the process of restoring the original shape and thickness of metal are eliminated, and the rigidity and strength of sheet metal parts are maintained.
Grinding burr: Grind a buffer slope at the joint between the damaged part and the surrounding paint film, so that the newly sprayed paint surface can be better connected with the original car paint surface.
Apply epoxy primer: clean and degrease the polished damaged surface again, apply epoxy primer and dry it for rust prevention.
How much is automotive sheet metal?
By August 202 1, the price is about 300- 1000 yuan.
Generally speaking, after the vehicle is collided, it is necessary to paint the body panels. A sheet metal worker is a person who can restore deformed objects to their original state. Slight, deformed in appearance, serious, such as crashing into two pieces, pressing into a thousand-layer cake, squeezing into a sandwich, etc. It can be repaired, so some used car dealers say that you should consider the whole car sheet metal and see how far this sheet metal is. Painting is very simple, that is, after the vehicle is restored to the state before being hit, the color and luster are restored.
Matters needing attention in automotive sheet metal processing
Try not to get wet in the rain or wash the car after maintenance 1-3 days: the car paint is not completely dry after painting. If you encounter water, it will affect the paint surface, so try not to touch water a few days before washing the car until the paint is completely dry.
Solve the problem in time: if the car paint appears cracking, fading, etching, water stains, orange peel and other phenomena, it must be repaired in time, and it cannot be delayed for a long time, resulting in paint surface corrosion.
How much is automotive sheet metal once?
Automotive sheet metal once around 400 yuan.
The repair of vehicles in collision accidents is no longer a simple automotive sheet metal knock, and the quality of repair can not be observed only by naked eyes. Maintenance personnel should not only know the technical parameters and dimensions of the car body, but also master the characteristics of the car body material, the transmission of force characteristics, the deformation trend and stress points of the car body and the production technology of the car body such as welding technology.
On the basis of mastering this knowledge, maintenance personnel should also use advanced measuring tools and accurate three-dimensional measurement of the car body to judge the direct and indirect damage and deformation of the car body and the hidden dangers caused by the deformation of the car body, formulate a complete car body repair plan, and then cooperate with correct maintenance technology and accurate three-dimensional data of key points to restore the car body to its original position and restore the damaged car body to the factory state.
material requirements
1, the sheet metal material must have good plasticity. Must have the ability to produce permanent deformation under the action of external force without being destroyed. For cold-worked parts, good cold plasticity is required, such as stamping parts of automobile parts; For hot working parts, good thermoplasticity is required, such as hot forgings, spring steel plates, hot rivets, etc.
2. Good weldability. Many automobile sheet metal parts are welded together by spot welding, oxygen welding, arc welding or gas shielded welding, so it is required that the sheet metal parts must have good welding performance. This is especially important in automobile maintenance and repair. Materials with good weldability have high welding strength and low cracking tendency.
3. Low price, economy and practicality. For any part of an automobile, the economy should be considered under the condition of meeting the working conditions. You can use ferrous metals instead of nonferrous metals; If you can use non-ferrous metals, never use precious metals. The service life of automotive sheet metal parts should be compatible with the service life of other automobile parts.
The car door was scratched and there were several small depressions. How much can it be repaired?
I looked at the scratches on your car. If it needs to be repaired, it will cost seven or eight hundred yuan. Due to different charging standards in different regions, if the car door is slightly dented after being scratched, but the primer of the car is not damaged, the repair cost is generally between 300 and 500 yuan. If the scratch has damaged the car's primer, it needs to be painted and painted, and the repair cost may be about 1000 yuan. For example, my watch is still good. I didn't scrape the primer. I remember spending more than 400 yuan.
The repair price of dents in your car door is mainly related to the location, size and depth of dents. Take your car door as an example. If dents occur at the edges and ridges, the dent area is large, or the dent has a certain depth, it will increase the difficulty of repair and the price will naturally be higher.
You also need to make a detailed inspection on the spot. If the door is badly scratched and the reinforcement inside the door is injured, it is necessary to replace the door of the vehicle, because the reinforcement inside the door can protect the vehicle and improve the driving safety of the owner.
When we are repairing vehicles, we try to choose a large garage to repair vehicles in the automobile 4s shop, because the mechanics of this institution are mature and this institution has perfect after-sales service. If you have any problems in the later stage, you can directly connect with the after-sales service.
After driving or parking, you must observe the surrounding environment to prevent the door or other parts of the car body from sinking due to collision. Installing a protective pad on the door is also a good way to prevent the door from being damaged.
How much is the right front fender body sheet metal painting?
Generally, the price of 2000 yuan in automotive sheet metal is calculated by the surface, and the price will change according to your requirements because the sheet metal will be painted. It is recommended to consult directly in the store. Automotive sheet metal is a technical means of automobile repair. In this respect, automotive sheet metal is equal to the repair of automotive sheet metal, which means that the car body should be repaired after a collision.
The functions of the pick are as follows:
1、? With the help of fluid mechanics, the drag coefficient is reduced and the driving is more stable.
2、? In the process of driving, avoid the sediment rolled up by the wheels splashing to the bottom of the car.
Because the front wheel has steering function, it is necessary to ensure the maximum limit space when the front wheel runs, so the designer will use the "wheel lion diagram" to verify the design size of the fender according to the selected tire model size.
