What happens when the front fender is too soft, why is the fender soft in the car

Junior high school physics tells us that sound is generated by the vibration of objects. So what are the car noises? 1. Engine noise, the vehicle engine is one of the most noisy vehicles, and its noise generation is different with the different engine speeds (mainly through:

Front fenders, hoods, fire barriers, exhaust pipes generation and transmission). 2. Road noise, road noise is generated by the noise caused by the wind cutting into the vehicle at high speed and the chassis vibration driven by driving, and the sand and gravel on the road will also produce noise from the chassis of the car, which is the main road noise (mainly through: four doors, trunk, front fenders, front wheel arc generation and transmission).

3. Tire noise, tire noise is generated by the friction between the tire and the road surface when the vehicle is driving at high speed, depending on the road conditions to determine the size of the tire noise, the worse the road conditions, the greater the tire noise, and the asphalt pavement and the concrete pavement are very different from the tire irritation (mainly through: four doors, trunk, front fenders, front wheel arc generation and transmission). 4. Wind noise, wind noise refers to the pressure of the oncoming wind in the process of high-speed driving of the car has exceeded the sealing resistance of the door and entered the car

Four-door seal clearance, including integral thin steel plate generation and transfer). 5. Resonant noise and others, the car body itself is like a box, and the sound itself has the nature of refraction and overlapping, when the sound is transmitted into the car, if there is no sound absorption and sound insulation material to absorb and block, the noise will continue to refract and overlap, forming a resonant sound (mainly through: noise into the car, superimposed, reflective).

So what is the function of shock absorbers? Shock absorbers (shock absorbers) are installed inside the suspension system of most cars to accelerate the attenuation of frame and body vibration to improve the driving smoothness and comfort of the car. The shock absorber is mainly used to suppress the impact from the road surface after the spring is absorbed.

When passing over uneven roads, although the shock absorbing spring can filter the vibration of the road surface, the spring itself will also have reciprocating motion, and the shock absorber is used to suppress this spring jump. If the shock absorber is broken, it will definitely produce abnormal noise, and generally speaking, it has little impact on car noise.

The forerunner is too soft to be a problem with the manufacturing principle, as long as it can be done elsewhere.

If the fender is not soft, it will not be able to absorb the collision energy in the event of a car accident, and the energy will be transmitted to the cab to deform the cab and threaten the safety of the driver and passengers.

Single-layer steel plate stamping, no reinforcing plate support, energy-absorbing design.

Logo There are several models of Maple that are still plastic fenders.

Hello, this fender can be repaired by heat treatment and then spray painted.

If it is a simple deformation, it can be suction and restored, and the paint can be repaired, and if it cannot be repaired, the fender can be replaced].

The plastic fenders of this motor vehicle are deformed, this is very simple, and it should be perfectly restored to its original appearance by going directly to the outside auto repair shop through sheet metal painting.

If the front bumper and fender are deformed, you can go to the auto repair shop to repair the sheet metal painting, ** cheaper.

It should be said that if there is a deformation in the appearance of the motor vehicle, this can be done directly to the 4S shop or the outside auto repair shop to paint the sheet metal, and there is no need to worry about this.

Hello, there are few plastic models of fenders, generally made of metal, if the fenders are deformed to see the degree of deformation, if the deformation is not big and does not hurt the paint, you can choose to repair without traces.

Hello, if it is deformed, this can be repaired by going to the repair station for gold spray painting, and this is not difficult.

If the fender is deformed, you can go to the repair shop to repair it through sheet metal, and you can paint it.

The deformation of the plastic fender in front of the car should be solved by spraying paint after the sheet metal repair of the maintenance plant, which is generally about 400 yuan.

Hello, this can be done directly to the store for sheet metal processing, and if it is not serious, it will be about 200.

Hello, this fender should be iron, and this one can be treated with sheet metal painting.

Hello, if the leaf plate of the vehicle is painted with sheet metal, it should be between three and five hundred yuan. Specifically, look at the degree of deformation of the fenders.

It's all a question that is not answered. Can plastic be sheet metal, is it heat treated and thermoplastic welded?

I can't see the picture, if it's not very serious, you can plate gold, if it's too serious, you have to change it,

In your case, sheet metal will do!

The specific measures are as follows:

Use a movable socket wrench and a screwdriver to remove the rubber strip under the front windshield first, and then remove the fender screws in order, and remove the fender lining in 20 minutes. The iron plate is not thick, do not use an iron hammer or anything, otherwise it will backfire, use a small rubber hammer, cushion the cushion, otherwise the paint surface will be damaged. If there is no rubber hammer, you can wrap a towel around a wooden stick and gently hammer it the same, after hammering it back, install it back in situ, and it will take 60 minutes.

2.Disassemble the point liner, use the tire as the fulcrum, make a small wooden block and put the groove on it, and the stick is on top of it.

3.Pull it out with a shape repair machine or an electric suction cup.

4.Find a paint shop for sheet metal painting, if there is a depression, you need sheet metal treatment, this look is basically about 200.

1. If the paint on the dent has been damaged, people who know how to know it will cause great difficulty for the technician to find a point when repairing, the most important and critical point in the repair of the car dent is to find the point, and the inaccurate point will only make the dent more and more bad, without rich experience in repairing the car, the technician who has not reached the point of being pure is helpless against the depression.

2. The second is to repair the paint, the repair paint is also very technical, but it looks very untechnical, many car owners do not repair the paint the more ugly, because they do not understand the skills of the paint, the technician who repairs the paint can repair the damaged paint to 80% of the realm (of course, it can never achieve the effect of spray paint).

3. The depression is very sharp, and on a line of paint loss, due to the excessive force of the sheet metal, two ridges of nearly 90 degrees have been folded, and it is not easy to repair these two ridges. The sharper the depression, the higher the requirements for finding the point, and the inaccurate finding of the point will lead to obvious pitting after repair, which is a big challenge for the technician.

4. The area of the depression is two palms the size, such a large depression is very sharp, and it is not only a long time to repair, but also a test of the technician's patience.

5. In the process of repairing the car depression, there is a knack for the repair of the large depression, many beginners see that the large depression has no way to start, the master is very experienced, as long as the self-stress point of the depression is found, and the force is applied after the identification, the large depression can be leveled out about 50%, so that the large depression is decomposed and repaired, the large depression is decomposed into several small depressions, and the small depression is then decomposed into more smaller depressions, and finally decomposed into countless points, and each point is repaired point by point.

6. The work after the depression is repaired is to repair the paint, of course, not all the depressions need this step, only those depressions that have some paint are necessary, and as long as the original car paint is almost small, the possibility of inserting the paint off is very small.

Disassemble the point liner, use the tire as the fulcrum, make a small wooden block and put the groove on it, and the stick is on top of it.

If the body is depressed and painted, it is recommended to paint sheet metal, about 300 to 500, but if there is no paint off and you are very concerned about the original paint, you can try the paint-free car dent repair technology, no need to destroy the original car paint for body concave repair, the principle is actually very simple, it is based on optics and mechanics, and the use of the lever principle to slowly restore the pits of different depths to the original appearance, look at the following picture You can see it at a glance.

Similar to the one in the picture, it is generally about 300 yuan.

The picture below is the repair effect of our sharkskin car dent repair direct store**, the first one**The black border area on the left is the appearance of the original painted body, and the right is the appearance of the body after repair, how can you feel the specific effect, but after all, there are so many stores in the country that the car dent repair can not be generalized, so I recommend that you still go to the regular brand store to repair, so that the technical level will be *** and**fixed, unlike small shops, which will only shout prices all over the sky.

It depends on what part it is, if it is a soft pit, it can be heated and ejected from the inside, and it can be repaired without lacquering! Don't do lacquer either, but there is a fee! Can you do it yourself, find a sheet metal fast repair shop to solve it!

So if you can do it? Hope it helps you and have a great time! [If you have a problem with the car, ask the car master.]

4S shop professional technician, 10 minutes to solve. 】

If you need sheet metal for deformation, see if the deformed area is large, if it is not big, it is not recommended to use sheet metal, and it is not cost-effective to repair the car a little bit.

If the fender is dented, it must need sheet metal painting, ** is about 400 yuan [If the car has a problem, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

Hello, as long as you want to repair it, you must have sheet metal forming [If you have a problem with the car, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

If you want sheet metal paint, ask the car master if you have a problem. 4S shop professional technician, 10 minutes to solve. 】

I don't know if it's self-pay or the insurance company's compensation. If you pay for it, it is cheaper to repair it, and the fender board itself (professionally called fenders) is not a very strong material, and it needs to have a pedestrian protection function, so it does not need to be more strong; If the insurance company pays, it is of course better to replace it with a new one, after all, the effect of spraying paint is better.

Fender dents can only be repaired with sheet metal and then painted.

This is best to go to a repair shop for a sheet metal repair, and if it is more serious, it is better to replace it with a new one!

If you seem to be in this situation, you can go to the repair shop and do a sheet metal painting directly to repair it.

This can be repaired by going to an outside auto repair shop, depending on the specific extent? Generally speaking, about 300 can be done.

Sheet metal, generally pulled out, or knocked out. Then touch up the paint.

Hello, if this wing plate is concave like this, it needs to be painted. About 300

1. The front and rear fenders of the car are iron.

2. If it is plastic, it cannot withstand collision.

Of course. Plastic can't withstand collisions, and smaller collisions are probably not a big deal, but the reverse is a big deal.

If it is an engineering plastic, there is no problem, not only does it not affect the collision, but also can better absorb the collision force and protect the safety in the car.
