Generally, Petrol Car sheet metal products require surface treatment after processing. What should be paid attention to in the surface treatment of Honda Car sheet metal stamping parts, how to deal with deformation problems, and the general surface treatment of Petrol Car sheet metal stamping parts processing is as follows:
1. Aluminum alloy castings for Petrol Car cannot be anodized with sulfuric acid;
2. Deep grooves or deep holes usually refer to parts whose depth exceeds more than 2 times the diameter or opening width, but parts with exquisite craftsmanship and not subject to this restriction will be electroplated, and their inner surfaces will not be completely covered by the plating;
3. In order to improve the corrosion resistance of bright nickel-plated steel parts, Petrol Car copper plating or dark nickel plating can be used as primer.
4. Zinc-based alloy plates are usually used to process electroplating layers for protective decoration. In order to improve the adhesion of the plating layer, pre-plating copper or nickel is usually required;
5. The spot welding parts can be chemically treated, but electrochemical treatments such as electroplating and anodizing are not allowed;
6. For electroplated and oxidized parts that require riveting, the processing process must be electroplating or oxidation first, and then riveting;
7. It is best to phosphate the steel before spraying to increase the adhesion of the coating.
