1、Cleaning of metal etching processing parts
The main reason is that the surface of the etched product workpiece has a certain residue of etching solution that will lead to the leaching of the finished product and color loss.
2、Demoulding treatment
After etching clean water treatment, the surface is still covered with the previous corrosion protection layer, which needs to be dried and processed. This protective layer is to protect the part that is not corroded, forming the type of pattern desired by the drawing, after passing the first self-test in line with the process, the need for batching through the demolding machine for the overall demolding so as to get the final stainless steel products.
3、Surface antirust treatment and coloring
Surface rust treatment according to customer needs, including coloring mainly black, gold, nickel plating is a common way, in specific products need to do passivation treatment and protective treatment to prevent cuts and so on.
