Bumper - A safety device that absorbs and mitigates external impacts and protects the front and rear of the vehicle.
Automobile bumper is a safety device that absorbs and slows down the external impact force and protects the front and back of the body. Many years ago, the front and rear bumpers of the car were pressed into channel steel with steel plates, riveted or welded together with the longitudinal beam of the frame, and there was a large gap with the body, which looked very unattractive. With the development of the automotive industry and the large number of applications of engineering plastics in the automotive industry, car bumpers, as an important safety device, have also moved towards the road of innovation. Today's car front and rear bumpers in addition to maintaining the original protection function, but also the pursuit of harmony and unity with the body shape, the pursuit of its own lightweight. The front and rear bumpers of cars are made of plastic, and people call them plastic bumpers. The plastic bumper of a general car is composed of three parts: an outer plate, a buffer material and a beam. The outer plate and buffer material are made of plastic, and the beam is made of cold rolled sheet and stamped into a U-shaped groove; The outer plate and cushioning material are attached to the beam.
What if the rear bumper splits?
1. Spray paint. If the bumper is only damaged by paint on the surface, it can be repaired with spray paint.
2. Repair with a plastic welding torch. The crack is heated with the plastic welding gun, and the plastic welding rod is fused on the crack to repair the gap.
3. Sandpaper. For relatively shallow cracks, you can sand the cracks with water sandpaper, and then polish with coarse wax and mirror wax.
4. Fill with stainless steel repair mesh. Wipe the dust and impurities on the surface of the bumper, cut the appropriate stainless steel repair mesh to fill the cracks, fix it with electric soldering iron and scissors, fill the repair strip and atomic ash, and then spray paint.
5. Replace the bumper. There is a large area of cracks on the bumper, even if it can be repaired, the buffer effect is not very good, and a new bumper must be replaced.
The front and rear bumpers of cars are safety devices that absorb and mitigate the impact of the outside world. If the vehicle is hit, it is also necessary to check whether the anti-collision steel beam behind the bumper is damaged and replaced.
Like the use of plastic welding torch this method of repair is somewhat difficult, bad treatment, but also damage the primer, if you can not solve or should go to the repair shop for repair.
Can the rear bumper dent be repaired?
When a vehicle rear-end accident occurs, the rear bumper is often the first to be damaged, resulting in dents. So, can the rear bumper dent be repaired? The answer is yes. Here are three common fixes.
Step 1 Use hot water
Using hot water to repair dents is a common method. Since the bumper is a plastic product, it will become soft when heated, so pour hot water on the dent, and then push the dent back into place with your hand. This method is simple to operate, but may not work well on parts with deeper dents.
2. Use a stun gun or solar power
In addition to using hot water, stun guns or solar energy are also common heating methods. Compared to hot water, stun guns or solar energy are more convenient, more stable and faster. The principle is similar to that of hot water.
3. Use special repair tools
If hot water or a stun gun cannot repair the dent, a special repair tool can be used.
