Introduction to jewelry plating process
What is electroplating? Electroplating is the process of using the principle of electrolysis to plate a thin layer of other metals or alloys on the surface of certain metals. It is a process of using electrolysis to attach a metal film to the surface of a metal or other material to prevent metal oxidation ( Such as rust), improve wear resistance, electrical conductivity, reflectivity, corrosion resistance (copper sulfate, etc.) and enhance aesthetics.
Common electroplating methods are: continuous plating is to drag the plated parts with the connected material into the electroplating tank of the planned process; barrel plating is to put the bulk plated parts into the drum, and then put the drum into the plating tank Electroplating. Hanging plating is to hang the plated parts on the hanger, and then put the hanger into the plating tank for electroplating.
General electroplating process: first clean and activate the substrate surface to improve plating efficiency and surface adhesion; electroplating a substrate surface electroplating film; post-processing to remove and dry the electroplating residues to prevent the plating layer from variation and poor quality.
Electroplating inspection: The appearance inspection mainly depends on the appearance of poor plating, discoloration, and peeling of the plating layer. The corrosion resistance test of electroplating products includes salt spray test, nitric acid steam test, H2S steam test, SO2 steam test, water vapor aging test, and the jewelry must not be oxidized after the test.
