Metal plate etching machine is a device that uses chemical reactions to perform metal etching. Its main principle is to use a specific acidic or alkaline solution to produce a chemical reaction on the metal surface to achieve a certain etching depth and shape. The application of metal plate etching

1. Cleaning of etching partsAfter the etching is completed, the etching parts should be washed in time. If necessary, use the diluted neutralization solution to neutralize it, because the etching solution is a very corrosive liquid. If it is residual on the surface of the etching workpiece, it will
