First, the steps of wheel plating
The first step: detection
Check whether the wheel hub is deformed, bouncing up and down, and swinging left and right.
The second step: shaping and filling the gap
The aluminum alloy fusion welding technology is used to fill the gap, which completely solves the shortcoming of the general wheel hub refurbished putty as the filling is not firm (if there is no gap and no deformation, this step is unnecessary).
The third step: paint stripping treatment
Taking off the corrosive and aging paint is different from the general wheel hub refurbishment, which is directly hand-polished or does not peel off the paint, which may lead to the shortcomings of unstable wheel peeling in later stages.
Step 4: Polishing and polishing
①The surface of the original wheel hub is relatively rough, ②The screw hole and valve hole of the wheel hub are uneven, ③The wheel chassis uses polishing and grinding technology to completely achieve the surface of the wheel hub and the perfection of the wheel hub details, completely solving the general wheel hub refurbished surface unevenness and wheel details such as Disadvantages such as peeling of screw holes.
Step 5: Clean the foam
Five procedures are used to clean the hub, and the refurbishment of the hub starts from the root cause to ensure the flawless standard for repairing the hub.
Step 6: Spray mustard paint
The wheel hub is sprayed with powder and melted at high temperature. The bottom adopts powder coating technology, which solves the shortcomings of poor wheel hardness and poor adhesion caused by the general wheel hub refurbishment manufacturers using paint for the bottom.
Step Seven: Electroplating
The wheel hub enters the dust-free electroplating production line for electroplating and baking.
The eighth step: spray paint
The wheel hub is sprayed with top paint, and then baked to make the hardness can reach more than 2H, which can reach the standard of flawless surface of the wheel hub.
Step 9: Salt spray test
After the hub is electroplated, a salt spray test is carried out to detect the salt spray corrosion resistance of the hub, so that the corrosion resistance of the hub is greatly improved.
2. Matters needing attention in the process of wheel hub electroplating
1. During the electroplating process, it is necessary to prevent the power outage in the middle.
2. All electroplating on aluminum needs to be charged into the tank to prevent the generation of replacement layer.
3. Aluminum parts electroplated in hot solution should be preheated in a hot water tank.
4. The water should be shaken dry as much as possible before the aluminum parts enter the acid etching to avoid local over-corrosion.
5. The first steps in the pre-treatment process of aluminum wheels should be carried out quickly, and the shorter the turning time is, the better to avoid re-oxidation.The copyright belongs to the author www.jihoowheels.com .
