Microporous etching mesh is to use chemical etching to etch metal. The processing thickness is usually 0.05-1.0mm, and the diameter of the processed micropores is more than 0.15mm. The material is mainly stainless steel. After cutting, washing, coating Fabrication, exposure, development, repair, etching, ink removal, inspection, disassembly, packaging and other processes can complete the formation of microporous etched mesh. If it needs to be made into a mesh cylinder, stamping and welding processes are required. To the oil injection process, the micro-hole etching is applied to the supporting products, which is more beautiful and elegant.
