RENOVATION PROCESS
The individual stages of renovating a steel car bumper
1. REMOVAL OF OLD COATINGS
Preparation of photographic documentation and evaluation of its damages. Chemical or mechanical removal of previous paint coatings or electroplating layers and corrosion products.
2. METAL WORK
Preparing parts for copper plating, which includes repairing all damages. This includes eliminating bolt holes, adding studs, welding parts together, and adding patches depending on the specific requirements.
3. COPPER PLATING
Electrochemically depositing a layer of copper onto the surface as an undercoat. This layer ensures good adhesion to the surface and provides corrosion protection.
4. POLISHING
Repeating the grinding process to achieve a smooth and straight surface. If necessary, the copper plating and grinding process is repeated. If the surface is straight, it is polished and then nickel-plated.
5. NICKEL PLATING
Placing the object in a nickel plating bath and depositing a layer of nickel onto its surface.
6. CHROME PLATING
The final process involves applying chrome which gives the surface a distinctive, durable shine as well as enhances its corrosion and wear resistance.
RENOVATION PROCESS OF ZINC CASTINGS
The stages of renovating a broken zinc casting door handle
1. PREPARATORY WORK
First, we prepare photographic documentation and assess the corrosion condition. We develop a plan of action to best accomplish the chrome plating or restoration of each part. Then we remove previous paint coatings and electroplating layers.
2. MECHANICAL PROCESSING
Removal of corrosion products through grinding and sanding.
3. FURTHER PROCESSING
If necessary, prepare areas for soldering, drilling, milling, and grinding.
4. COPPER PLATING
Electrochemically deposit a layer of copper onto the surface as an undercoat. This layer ensures good adhesion to the surface and provides corrosion protection.
5. FILLING IN GAPS
Filling in gaps with solder.
6. SHAPE RESTORATION
Grinding to restore the original shape of the component.
7. COPPER PLATING
Applying another layer of copper over the tin coating to achieve a uniform and smooth surface.
8. NICKEL PLATING
The object is polished and then subjected to the nickel plating process, which provides corrosion resistance and a mirror-like shine.
9. CHROME PLATING
Chrome plating protects the nickel coating from losing its shine, imparts a silver-like color, and enhances the hardness and corrosion-resistant properties of the surface.
