How Does Wheel Repair Work?

Dec. 19, 2019

The wheels of today's automotive industry are usually made of Aluminum Alloy Wheels. However, the wheels rotate for a long time, and often even friction with the road edge, so it is almost inevitable that there will be some wear. Does it actually work? Is the operation complicated? It is said that in some cases, repairing the wheel hub will bring new potential risks. Today ODM Machined Finish Wheels Wholesaler will answer the wheel repair technology in detail for everyone!

Generally, the damage of aluminum alloy wheels can be basically divided into three categories according to the cause and degree of damage.

1. Surface abrasions and abrasions, which are commonly found when parking on the side of the road in intimate contact with the road teeth.

2. Major deformation and distortion, which are often encountered when high speed suddenly encounters large pits or high ridges.

3. Fracture, common in impact and high-speed impact.

The repair methods for these three situations are also different, and the effect varies from person to person, and even some cases will bring new dangers. What is the specific situation? Keep watching!

Surface abrasion repair. This is also the most common situation we usually have. Because it does not affect the force structure of the wheel hub, it only needs to beautify the surface. The process is also mature and worth repairing.

(1) Sandblasting:

First of all, the surface of the wheel must be roughened before repairing. The wheel is mainly cleaned by sandblasting to lay the foundation for subsequent beautification.

(2) Sandpaper polishing:

After most of the wheels have been cleaned by dust-free blasting, the details are then repeatedly polished with a finer sandpaper.

(3) Atomic ash filling:

After the wheel has been polished and flattened, the scratches are filled with alloy putty. This step is well understood. It is the same as filling with automotive ash with atomic ash.

The difference is that the alloy atomic ash is used on the wheel, which is harder and more delicate than the ordinary atomic ash used on automotive sheet metal.

(4) Aluminum welding fill:

This situation is usually caused by a slightly larger gap at the wear site, and the atomic ash fill effect is not good. Aluminum welding will be used to fill the aluminum alloy.

(5) Polishing:

Because the fill generally exceeds the original flat surface, the repair location needs to be sanded so that the final metal remains approximately flat.

(6) Professional spray paint:

This step is just like the sheet metal spray painting of most repair shops. The difference is not large, and it is more a test of the color difference and uniformity of the spray paint. The master is more able to guarantee the final result.

(7) Lathe programming:

However, because the wheels of some models have bright surfaces and wire drawing processes, they are not suitable for grinding only, and need to be finished by CNC machine tools. At this time, it is necessary to obtain accurate details of the wheel's correct radian and spacing to ensure the final Brushed effect.

(8) CNC wire drawing:

After programming, the wheel is finely cut with a lathe to ensure that the final surface is the same. In addition, this step will reduce the thickness of the hub, so it should not be repaired multiple times, because the thinner support surface of the hub will greatly affect the force performance of the hub.

(9) Nano metal protective varnish:

After the previous steps are completed, the wheel hub needs to be sprayed with nano-metal varnish. After baking, it will be more shiny and less prone to wear.

(10) Fine polishing:

Finally, the wheels are finely polished to make the effect more shiny.

In addition to the second and third types of damage, due to changes in the structure of the hub and even breakage, after this situation is repaired, the force capacity and internal structure of the wheel itself are no longer as complete as before The impact on safety will be very large, so it is not recommended that everyone repair the deformation.

The above is the wheel repair work introduced by Aluminum Alloy Wheels Supplier.
