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

After etching, the product is the original color of the metal, and many require subsequent surface coloring treatment: surface color whitening treatment; surface mirror bright treatment; surface coloring treatment. 1. Surface whitening treatment: During the processing of precision etched products,

The laser etching process is similar to the manufacture of printed circuit boards, where exposure to UV light transfers an image of a component onto a photoresist-coated metal. The unexposed photoresist is then washed away, leaving the bare metal etched. In tank etching, the prepared board is dipped

Etching of metal products, whether it is copper, aluminum, stainless steel, nickel sheets,etc. after the material manufacturer produces metal materials, some will apply a layer of anti-rust oil on the surface, and some will only attach a layer of protective film to the surface. The surface of the pr

Magnesium alloy sheets are widely used in the printing field, and the demand for sheets is very large and is increasing rapidly. In fact, magnesium alloy sheets have been widely used in the printing field as early as 40 years ago, mainly in Europe and the United States. In China, copper plates and z

Before metal etching plates become exquisite handicrafts, they all need to undergo precise processing technology, so how are metal plates etched?1. Inspection of metal materials:When the metal plate of the raw material needs to be etched, it must be inspected first, that is, the work we need to do i

1. The corrosion process of galvanized sheetDuring the entire service cycle of galvanized sheet, the first corrosion that occurs is the oxidation of the galvanized layer on the surface. After a longer time to generate "white rust", the "white rust" on the surface further reacts with impurity gases s

The etching processing methods of magnesium and alloys are as follows:Mg is a very active metal and can react with a variety of acids. Among them, the corrosive solution based on H2S04 is easier to control and has been widely used in chemical etching of aviation parts. The reaction formula is as fol
