We all know that in the production process of using chemical nickel plating additives for aluminum workpieces, zinc precipitation water needs to be used for zinc precipitation, so that the adhesion of the chemical nickel coating after zinc precipitation is better.
A customer inquired about how to add a good passivation agent during the production process of using trivalent chromium blue white zinc passivation agent?
A customer inquired that during the production process of using acidic copper plating brighteners, sometimes the brightness of the acid copper coating is relatively poor. So what is the reason that affects the brightness of the coating?
A customer inquired that the use of chemical nickel additives in powder metallurgy parts can cause many problems in the surface treatment process due to the unique structure of the workpiece. So, what would be the better pre-treatment process for these powder metallurgy parts?
A customer inquired about the use of plastic electroplating palladium activator in production. In order to achieve good activation effect on the surface of plastic workpieces, what should be paid attention to in the maintenance of the activation solution?
