After etching, the products are metal color, and many of them need subsequent surface coloring treatment: a surface color whitening treatment; b surface mirror bright treatment; c Surface coloring treatment.1. Surface color whitening treatment: precision etching products in the process of processing

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

The pretreatment processes for metal corrosion mainly include: photosensitive etching, screen printing, and stickers. Each process has its own advantages and disadvantages.
