Electroplated aluminum wheels are also divided into electroplated silver, water plating and pure plating. Although the electroplated silver and water-plated aluminum wheels are bright and vivid, they are kept for a short period of time, so the price is relatively cheap. The color of purely electroplated aluminum wheels lasts for a long time, which can be said to be high quality and high price. So, do you know what steps are needed for electroplated aluminum wheels? In general, the electroplating of aluminum wheels requires the steps of inspection, shaping filling gap, stripping treatment, polishing and polishing, washing and soaking, spraying mustard paint, electroplating, spray coating, salt spray test and the like. Let's take a look at the details with Xiaobian!
The first step: testing
Detect whether the aluminum hub is deformed, jump up and down, and swing left and right.
Step 2: Shaping the gap
The aluminum alloy fusion welding technology is used to fill the gap, which completely solves the shortcomings of the general aluminum wheel refurbishment of the ash as the filler is not strong (if there is no gap and no deformation, this step is not needed).
The third step: stripping treatment
Taking off the corrosive aging paint, unlike the general aluminum wheel retreading, direct hand grinding or non-painting leads to the disadvantage that the aluminum wheel is not peeled off in the later stage.
The fourth step: polishing and polishing
1 The original aluminum wheel surface is rough,
2The screw holes and valve holes of the aluminum hub are rugged.
3 aluminum wheel hub chassis, using polishing and grinding technology to completely achieve the aluminum wheel surface smoothing and aluminum wheel detail perfect, completely solve the general aluminum wheel refurbishment surface irregularities and aluminum wheel details such as screw hole peeling and other shortcomings.
Step 5: Cleaning the infest
Five-way cleaning of aluminum wheels, aluminum wheel refurbishment from the roots, to ensure the standard of repairing aluminum wheels without flaws.
Step 6: Spray mustard paint
The aluminum wheel is sprayed with powder and melted at a high temperature, and the powder coating technology is used at the bottom to solve the defects of poor hardness and poor adhesion of the aluminum wheel hub caused by the general aluminum wheel refurbished manufacturer.
Step 7: Plating
The aluminum wheel hub enters the dust-free plating line for electroplating and baking.
Step 8: Spray finish
The aluminum wheel is sprayed with a top coat, and then the hardness can reach 2H or more in the baking, which can meet the standard of flawless surface of the aluminum hub.
Step 9: Salt spray test
After the aluminum wheel is plated, the salt spray test is carried out to detect the salt spray corrosion resistance of the aluminum wheel hub, so that the corrosion resistance of the aluminum wheel hub is greatly improved.
Second, the aluminum wheel hub plating process notes
1. It is necessary to prevent power failure during the electroplating process.
2, the aluminum plating needs to be charged into the groove to prevent the generation of the replacement layer.
3. The aluminum parts plated in the hot solution should be preheated in the hot water tank.
4. Before the aluminum parts enter the acid etching, the water should be dried as much as possible to avoid local over-corrosion.
5. The first step of the aluminum-aluminum wheel pre-treatment process should be carried out quickly, and the shorter the transfer time, the better, to avoid re-oxidation.
