Chemical etching is the process of using industrial grade acids to etch information on various metals. An alternative to traditional engraving processes, chemical etching starts by masking the areas which are not going to be etched, and then bathing the substrate in an acid bath. The un-masked areas are then etched by the acid, without effecting the masked areas. Then the masking is stripped off, producing a perfectly etched substrate. The etched areas can then be paint filled to contrast with the metal surface.
The Chemical etching process can be used on Aluminum, Stainless Steel and Brass metals.
What is it used for:
Chemical etching is traditionally a higher end process. Used mainly for applications where the cosmetic appearance of the part is paramount and it is desireable to “feel” the information etched into the metal
- High End Nameplates and signs where it is desirable to feel the depth of the information etched into the metal as opposed to just printed on the surface as in screen printing and digital printing.
- Industrial Nameplates when it is anticipated that there may be surface abrasion that might remove the information on the Nameplate.
