Galvanic plating:

Its application is rich in metal product. The main process is to put the parts into the chemical plating solution.  According to the different needs of customers, the parts can be plated into different colors, with high gloss silver, silver, gray silver. Its conductivity of the electroplated product significantly enhanced. How to deal with some components required insulated?  There are two ways: First, to paint insulating oil on required area of the part. Of course, coated with insulating oil area will be black, it is not suitable as appearance side.  Second, to coved with special adhesive paste, to protect them, the same effect can be achieved.  

Vacuum plating:

Generally applicated to a wider range, such as stainless steel sheet and plastic products. Because of its complex process, high environment & equipment requirements, high cost, its price is more expensive than galvanic plating.  its process is : product surface cleaning -> spray primer -> baking primer -> vacuum coating -> spray paint -> baking finish -> packaging  The vacuum plating can be divided into general vacuum plating, UV vacuum plating,  The process consists of evaporation, sputtering, gun color and so on. 

 
Galvanic plating’s process is relatively simple, From the equipment to the environment, its requirement is not harsh as vacuum plating required. However, the galvanic plating has a weakness, which is that can only be plated with a simple stainless steel plate. The stainless steel is very resistant to plating, which makes its application range limited. But the vacuum plating can reach about 200 ℃, which can be used for high temperature parts of the plating treatment. In addition, the general requirements of high temperature parts, vacuum plating must be sprayed in the final layer of UV oil, so that the product surface is shiny, high temperature resistance, while ensuring adhesion.
