Metal etching machine China - etching,exposure,Surface finshing

We dividing the photo chemical metal etching machines in surface treatment & metal surface finishing industry into four process as following:

1. Pretreating: It's very important surface treatment to the metal surface finishing. It's include machinery and chemical pretreating.
2. Exposure: It's a ways to transferring the graphics to metal surface by film, UV light and UV glue. The graphics developed on the metal surface after exposure & developing.
3. Etching: It's a chemical or electrochemical ways of etching graphics on metal surface or cutting thickness metal into lots of complex shapes.
4. Surface finishing: Different ways made metal surface into different effects. Its including machinery (Such as threading, brushing), chemical and electrochemical ways (Such as plating, coating, electrolytic coloring).
