metal photo etched Brass EMI Shielding Manufacturers

Metal etching is a technique for removing materials using chemical reaction or physical impact. Metal etching technology can be divided into two types: wet etching and dry etching. Metal etching is composed of a series of complex chemical processes, and different corrosives have different corrosion properties and strengths for different metal materials.

Filter mesh is abbreviated as filter mesh, which is processed by metal wire meshes of different meshes. Its function is to filter molten material flow and increase material flow resistance, thereby filtering out mechanical impurities and improving the effect of mixing or plasticizing.

The filter is an indispensable device on the conveying medium pipeline.

Classified by the nature of the business card: Identity card business card. This type of business card is mainly used in government agencies, scientific research institutes, schools, finance, insurance and other units. The content of the business card mainly identifies the name, position, unit name and necessary communication methods of the holder, and the main purpose is to transmit the person's personal information.

Etching, usually referred to as etching, is also called photochemical etching. It refers to the removal of the protective film of the area to be etched after exposure and development. During etching, it contacts the chemical solution to achieve the effect of dissolution and corrosion, forming a concave-convex or hollow-out effect.

Due to the stricter enviroment control and increasing market demands, we are investing a new etching factory for our etching products department, new production machines and factory facility will be ready soon after our Chinese New Year in 2019, welcome your contact if you have any demands.
