How to do the pretreatment of the electroplating processing of stainless steel hardware products? It is everywhere in our lives. Do you know what the electroplating processing of hardware products is like? How to do the pretreatment? Let’s take a look together!

1. When electroplating, pay attention to the matching of the coating metal and the base metal.

2. The pretreatment of the electroplating processing of stainless steel hardware products should be done well. The cleaner the substrate is, the atoms of the substrate metal can be fully exposed, which is the key to the good adhesion of the subsequent coating.

3. The rationality of the baking temperature should also be paid attention to when baking the sealing paint for the electroplating processing of stainless steel hardware products.

4. If the high temperature baking treatment is to be carried out, the stress between the product and the coating should be considered. For example, after zinc or aluminum alloy plating, it cannot be baked at a high temperature.

5. When superimposing different coatings on stainless steel hardware products, pay attention to the matching between different coatings. The former coating should be cleaned, and if necessary, weak etching should be performed to eliminate the oxide film of the previous coating.
