Today we will talk about a manual repair technology for headlights. In our daily life, we often encounter a problem, which is the problem of yellowing and broken headlights. Once we encounter this situation, most places can only replace it without providing this repair technology.
Replacing car headlights not only costs expensive money, but some small damages are even unnecessary. Is it difficult to repair this kind of car headlight technology? Why is it not promoted on a large scale in China? Follow me and take a look at it Process it!
This is a car headlight that needs to be repaired. It can be seen from the picture that the headlight has an obvious damaged part, and the surface of the headlight is very yellow. The defects of these two types of headlights are also problems we often encounter. The yellowing of the headlights is mainly caused by the yellowing of the surface of the lampshade caused by long-term use of the headlights. Damage of the headlights is generally caused by collisions.
First of all, the headlight needs to be disassembled, mainly to disassemble the headlight. Since the outside of the headlight is fixed with colloid, it needs to be heated to soften it before it can be separated.
After heating, the separation method is very simple, just use a screwdriver to open it.
This headlight looks like it has seen a lot of time and needs to be cleaned first, both the inner and outer lampshades and housings.
After cleaning, use a heated tool to remove the damaged parts. The lampshade is made of plastic. After the tool is heated, it can be easily softened, making it easy to remove.
After the damaged part is removed, the surrounding area needs to be polished. The master is polishing it with a file.
After cleaning the damaged area, the master found a piece of accessories and cut it. Let's see how he does it, first placing the accessory on the damaged area of the lampshade, fixing it with a white powder and glue, and then cutting it from the inside with a razor blade.
This cut only cuts the rough outline of the damaged location.
The contour is then finished using a grinder, and finally the shape of the damaged location is cut out. Then polish the surrounding area to match the location of the damage.
At this time, use white powder to fill the gaps, and then glue them with glue. The repair of the damaged part is roughly completed, and only fine repairs are needed in the future.
After the bonding is completed, use a file to polish the surface area. This set of manual repair is mainly labor-intensive, and the operation method and cost are very low.
The yellowing on the surface of the lampshade is caused by the oxidation of the surface of the lampshade after long-term use. It is very simple to deal with it. Just use a blade to treat the surface. This process is very stress-relieving.
You can compare the results before and after the repair up and down. The yellowed things have obviously been scraped off.
If the blade scrapes something yellow, it will leave scratches on the surface of the lampshade. At this time, it needs to be sanded with sandpaper.
The master held sandpaper in his hand and polished the lampshade while dipping it in water.
After sanding is completed, you need to use a grinder for fine grinding so that the scratches can be removed.
The lampshade is done, but the inside still needs to be worked on. This headlight is too old, the internal paint is chipped, and it is severely damaged and needs to be repaired.
The master spray-painted it with self-spray paint.
Pay attention to this step. The electroplated aluminum inside the headlight is obviously damaged, and the master is using aluminum foil to paste it. This kind of manual pasting is obviously different from the original one. Through this, you can judge whether the headlight has been repaired.
This kind of repair is often a method used by blister trucks to save costs. This identification skill is very important!
After the interior and exterior of the headlight are repaired, they need to be closed. The master's operation is very simple. He heats the outer position and lampshade, and then melts them with heat to allow them to bond naturally. This operation is really simple and crude. Normally when we connect them, we usually use colloid to fix them.
This is what the final headlights looked like after they were repaired.
The headlight above is yellowing and aging, and the repair of the damaged internal lampshade only costs 5 US dollars. This saves most of the cost compared to replacing the headlight, but you can also see that the cost of the whole process is mainly labor, and the cost of accessories is basically OK. can be ignored.
Damage repair of headlights is actually available in China, but not particularly many. You can also find it in some car beauty shops. The main reason is that headlight repair is not as profitable as headlight replacement, so it is not common.
Moreover, if you look at the finished product after the headlight is repaired, the damaged position is still relatively obvious. It is not as perfect as car glass repair, so this is also the reason why a large number of people will not choose it.
It is not good in terms of aesthetics, but it does not affect the use of the headlights at all. In terms of economy, this saves most of the cost than replacing the headlights, which is very cost-effective!
