In Metal etching plate efore becoming a beautiful craft, precise processing techniques are needed, so how is the metal plate etched?

1、Metal raw material inspection.

When the raw material of metal plate needs to be etched, quality control is carried out first to polish the bad part of the product, etc.

2、Electrostatic dedusting, coating photopolymer, inspection：

Pre-static dust removal is required, the goal of which is to prevent the generation of static electricity will absorb dust through electrostatic dust removal. After the completion of the spraying oil, the role of spraying oil is to carry out photosensitization to prepare. After the product is sprayed with photosensitizing oil, the product is checked for spraying oil and residual oil.
3、Light-sensitive, development：

Sensitization is to place the film on the product sprayed with photosensitive oil mainly by exposing it on the product to form the pattern on the film. Special attention should be paid to the fixture during the exposure process. The film should not be bent, otherwise the product pattern will be bent and lead to product defects. The film should also be checked periodically and should not be folded, otherwise inferior products will appear. Development is performed after completion. The unexposed part is cleaned by developing liquid drug and the unexposed part is cured to form an etched pattern. After development, a quality inspector will check the product and select undeveloped parts or products with bad patterns.

4、Sealing oil：

The so-called sealing oil is in the process of oil spraying, in the edge of the product place, can not spray oil, oil filling process, the metal part of the product shall not be exposed, otherwise the etching will produce bad products. The product should be dried after oil injection. Check the product after drying.

5、Etching, cleaning：

Metal etching plateThe etching process is the key process in the whole production process.The desired pattern is formed mainly by the chemical action of the chemical solution that etches the exposed and developed stainless steel part of the product.Metal etching plateAfter the etching is completed, the product is cleaned to clean the excess paint, and then the product process is completed by slow pulling and other cleaning equipment.

6、Shipment Inspection：

The etching and cleaning process is followed by quality control to eliminate defective products from the production process and is completed and delivered to the finished goods warehouse for packing and shipping.
