Since ancient times,Metal etching processIt plays an important role in people's life. With the changing times and the improvement of people's aesthetics, the inherent color of the metal etching process out of the production of metal processes no longer meet people's needs, more and more people are pursuing the application of rich colors and artistic expression in the metal etching surface treatment process. The surface treatment process of metal processing is an important step in the process of metal etching process, which determines the final surface art effect of metal.

Etching treatment is a common process means for metal processing, generally using a strong acid solution to etch the metal surface. The common etching solution is ferric chloride, which is a very polluting and environmentally unfriendly thing. Simply put, etching treatment is to stop the part you want to keep, expose the corroded part, and then wash a corrosive bubble bath.

The above becomes the chemical etching method we often talk about.，Metal etching processLaser engraving and stamping processes are also included; the latter is commonly treated with an etching process due to the lack of burr and smoothness produced on the product.
