In the chemical etching process method, the parts or parts that have been coated with a graphic anti-corrosion layer are placed in the corrosive solution for corrosion, and the corrosion is continued until the metal thickness reaches the requirements or the graphic depth reaches the requirements. In

Etching refers to removing the protection of the area to be etched after exposure to plate making and development, and contacting chemical solution during etching to achieve the effect of dissolution and corrosion, forming the effect of concave-convex or hollow molding. The earliest can be used to m

In the product bronzing process, the choice of bronzing paper plays an important role, so the following 6 aspects should be paid attention to when choosing bronzing paper:1. Understand the substrate of the product. The bronzing substrate determines the series of bronzing paper.

Etching is a technique in which materials are removed using chemical reaction or physical impact. Etching techniques can be divided into wet etching and dry etching.
