You ever wondered how does chemical etching work? you are in the right place to find out.
The etching is a chemical process in which the metal is immersed in acid to take out the surface of the metal, remaining with a smooth beautiful design on it. It is a high precision process in which it can produce metal parts and design of need. Or it can be done with machines as a process of engraving that uses high temperature and high-pressure chemical spray to remove the metal material in order to create a permanent design on its surface. In short, this is how does chemical etching works.
Now let’s see the steps that are needed to be taken in order to perform an etching process. The process will be with the machines because is a lot more accurate and less dangerous than the made by hand with the acid.
First of all the metal material is cleaned to be sure that the surface is not contaminated and is prepared to start the process. A sheet of the material is laminated with a layer of resistance for light-sensitivity.
Then a photo tool with the design is placed on the metal material witch was laminated and then is set on the UV light. The UV light will make the laminated part become even harder and the part with the design because is protected will stay the same.
Before the etching process begins the laminated is heated to improve the acid resistance
After the metal material is made a set on the machine to be sprayed with a high-temperature spray. The solution will remove the unprotected parts from the metal and it will remain the form of the design.
When the process is done, the resist material is removed either in the stripping machine or manually.
Metal Materials that can be etched with this chemical process are:
And many more materials, but these are the most popular.
Did you want to know how does chemical etching work? Now you know, is a simple 5 step process through the machine that will produce in the end a smooth and clean design from the metal. First, one after the design is ready is the Lamination of the material. The second step is to put the metal material into the machine to make the laminated area even stronger and resistant. Then the film resists will make the area od design to be prepared for the etching process. The fourth step is to put the material trough etching machine where it will be sprayed with high pressure and high-temperature spray that will remove the unprotected parts. The fifth step is to remove the resits material either manually, either in the stripping machine.
