1. Pre-treatment should be done well. The cleaner the substrate is, the more the atoms of the base metal can be exposed, which is the key to the subsequent adhesion of the coating.
2, pay attention to the matching of plating metal and base metal during electroplating
3. Pay attention to the matching between different coatings when stacking different coatings. The former coating should be cleaned and weakly etched if necessary to eliminate the oxide film of the previous coating.
4. If high temperature baking is to be carried out, the stress between the product and the coating should be considered. If the zinc or aluminum alloy is plated, it cannot be baked at too high a temperature.
5, the sealing paint treatment needs to pay attention to the reasonableness of the baking temperature.
