How To Deal With The Etching Process

Etching is the most critical step in the metal plate pattern decoration process. How To Deal With The Etching Process?So if we want products with clear stripes and highly decorative patterns, how should we handle the strict control during the selective etching process? So the editor below will introduce to you how to handle the etching process.

Cleaning of etched parts:

After the etching process is completed, the etched parts should be cleaned with water immediately, because the etching liquid is a highly corrosive liquid. If residue remains on the surface of the etched product workpiece, it will cause corrosion damage or discoloration of the etched product.

Eliminate the corrosion-resistant protective layer:

The etched products are cleaned and dried to remove the protective coating. If you choose an adhesive organic film, it can be separated directly; if it is a paint or printing ink, use a reasonable organic solvent or chemical photo etching solution to dissolve and eliminate it.

Surface finishing:

The etched products can be surface-finished according to design requirements. If the surface is required to be smooth, chemical polishing can be carried out. On the one hand, it can completely remove residues such as corrosion-resistant materials, and it can also remove etching substances attached to the surface during the etching process. In addition, the surface gloss can be improved by polishing.

Surface passivation treatment or coloring:

If text processing or pattern design is to be performed after china metal etching process, the surface of the processed original must be passivated or protected. Products used in decorative designs can be painted or scraped.
