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?
What precautions should we pay attention to during the passivation process of different workpieces when using trivalent chromium colored zinc passivation agent?
We all know that in the production process of plastic electroplating, the adhesion of the coating is a common phenomenon. Although this phenomenon is often caused by incomplete oil removal on the surface of plastic workpieces, sometimes it is also important to pay attention to whether the roughening additive is used correctly!
