Process of mesh etching

Mesh etching processing is a technology for making metal screen mesh, and the process is to etch metal plates, such as stainless steel, copper plate, aluminum plate, etc., by chemical or physical methods to achieve the purpose of making screen mesh.

Specifically, the process of etching processing can include the following steps:

Preparing materials: selecting a suitable metal plate, cutting and grinding it for etching.

Coating protective layer: coating a protective layer on the surface of the metal sheet to prevent damage to the metal sheet during the etching process.

Pattern design: According to the need, the desired pattern or hole pattern can be designed on the surface of the metal plate.

Etching process: The metal sheet coated with the protective layer is put into the etching machine for etching process.

Remove the protective layer: After the etching process is completed, remove the protective layer from the surface of the metal plate.

Cleaning and inspection: The surface of the metal sheet is cleaned and quality inspection is conducted to confirm whether it meets the requirements.

Mesh etching processing is widely used in the following applications: precision filters are commonly used in the petroleum, chemical, food, pharmaceutical industries; metal leakage plate, cover plate, lead frame, metal substrate in the electronics industry is often able to contact; precision optical and mechanical plane parts, spring parts; friction plate and other concave and convex plane parts; metal patterns of complex and exquisite artifacts.
