Treatment method:
1, the first thing to do is to renovate the surface of aluminum alloy wheel hub. There are three processes for wheel hub surface renovation: full painting, bright surface and electroplating. The so-called full painting is to paint the surface of the wheel hub with colored paint. The conventional colored paint colors are silver, gray and black.
2. The full painting process is mainly aimed at slight scratches on the wheel hub surface. The first step of this process is divided into four steps, that is, spraying the base powder first, then putting it in the oven, spraying the primer, color paint and transparent paint for the third time, and finally baking it in the oven.
3. Bright surface means that the wheel hub after being put into the oven for the first time is re-processed by lathe, so that its surface is very flat and achieves mirror effect.
4. When the surface of aluminum alloy wheel hub is scratched, it can be electroplated again. First, the hub is polished and leveled, and then precision electroplating is carried out.
Extended data:
Repair of aluminum alloy wheel hub
Many aluminum alloy wheels are not only scratched in use, but also deformed and cracked. Then it is very important to repair the shape of the hub.
Generally speaking, the damage of aluminum alloy wheels of vehicles is caused by external forces, such as strong wear, environmental corrosion, hard object impact and so on. This will cause the wheel to break, twist and score. If we can correct and repair all kinds of aluminum alloy wheel injuries by using aluminum alloy professional technology and tools without destroying the mechanical properties and molecular structure of aluminum alloy.
If the hub is broken, the broken part can be welded again by argon arc welding of aluminum alloy. After welding, smooth the solder joint with a grinding wheel.
