I wonder if you are familiar with the plating process and quality testing standards of hardware. Today, Xiaobian and you all come to learn about it.
The traditional plating process of metal products can be roughly described by the following processes:
Mounting degreasing, washing rust removal, washing activation, washing electroplating washing drying inspection packaging.
New Technology of Replacing Electroplating
Common plating processes include galvanizing, copper plating, nickel plating, gold plating, silver plating, tin plating, chromium plating, rhodium plating, palladium plating and alloy plating. There are various kinds of plating, either single-layer plating or multi-layer plating: single metal plating (as mentioned above), alloy plating, composite plating and electroless plating. Vacuum plating and ion sputtering are also called electroplating. Such as aluminium oxidation, blackening/bluing, chemical polishing, electrochemical polishing, passivation and so on, also fall into the category of electroplating.
New Technology of Replacing Electroplating
The inspection of electroplated hardware should be based on appearance, corrosion resistance, temperature resistance, adhesion force, size and other aspects. If one or more of the products are not up to standard, it shows that there are slight or serious defects in this product. According to the objective data, many products produced by electroplating process have slight defects. The operation process is mainly affected by temperature, current, plating solution and other factors. The quality of some hardware products is not very optimistic.
