etching lid|After the metal is etched, these four steps must be done

Etching is the key to the pattern decoration process of the metal plate mold. To obtain a pattern product with clear stripes and strong decorativeness, the front, middle and back processes of the etching process need to be strictly controlled.
If the etching is not done properly, it will cause the corrosion-resistant coating at the junction of etching and non-etching to fall off or melt, which will make the etching pattern blurred and distorted, which will affect the beauty of the pattern and the decorative effect.
1. Cleaning of etched parts
After the etching process is completed, the etched parts should be cleaned and cleaned with water immediately, because the etching liquid is all strongly corrosive liquid. If the residue remains on the surface of the etched product, it will cause the etched product to be damaged or faded.
2. Eliminate the corrosion-resistant protective layer
The etched products are cleaned and cleaned and then dried to remove the maintenance coating. If the organic film is pasted, it can be detached directly; if it is architectural coating or printing ink, use a reasonable organic solvent or chemical solution to melt and eliminate.
3. Surface finishing
The metal etched products can be surface-finished according to the design plan. If it is specified that the surface is smooth, chemical polishing can be carried out. On the one hand, it can completely eliminate residues such as corrosion-resistant raw materials, and it can also remove the corrosive substances attached to the surface during the etching process. In addition, the gloss of the surface layer can be improved according to polishing.
4. Surface passivation treatment or coloring
If you want to perform text processing or pattern design after etching, the surface of the processed original should be exposed to passivation or safety protection. Products used in decorative design can be colored or scraped.
Coloring solutions can use organic chemistry, electrolysis and other coloring methods to color the etched products, improve the color and actual effect of the decoration design, can carry out the electroplating process decoration design coating, and can also paint a variety of colored plates Architectural paint becomes a decorative design piece in colorful colors.
