The method and effect of cleaning the mold of etching processing, etching processing uses a special mold, the cleaning agent of etching processing to clean the oil and impurities on the surface of the mold. What are the common defects of etching processing? A surface with oil has an anti-corrosion effect on the surface of the mold, which will cause uneven chemical corrosion, and it is not easy to stick protective stickers on the mold. Mirror protection after cleaning the special requirements of the surface to immediately protect the general mirror after cleaning will spray a layer of black paint as protection against rust and prevent scratching.

Etching process adhesive die, adhesive die method and effect. The use of special tape paste on the surface that does not need to be etched is usually pasted at least 30% of the tape paste is used to clean the etched surface again after the surface boundary is pasted. The common defect is that the boundary between the etched surface and the non-etched surface is not straight and the paste is not strong, which leads to the optimization of the multi-etched mold.

Etching

Method for chemical inspection of etching processing. Methods The pasted mold is soaked in chemical agents for a few seconds. The surface of the unpasted tape will be chemically corroded. 0.01 to 0.02 mm. The surface is black. The common defects of the mold are one material or uneven hardness, two trachoma and three burnt welding defects, and one material or hardness is not much different from each other.

Adjustment

The length of etching processing time, 2 trachoma is small, use that to fill trachoma and then etch. After welding, the difference in material and hardness is not large, the first method is used to solve the problem. When the difference in hardness is large, the local heating of the welding position can be heated and then the abrasive sand washing can be evenly sprayed on the surface of the corroded mold with a spray gun. The black oxidation of the mold surface is removed and the surface of the mold is silver after sand washing. Sad common defects sandblasting uneven surface washing is not clean, resulting in uneven etching.
