The process of custom metal etching begins with a design. This can be a hand-drawn sketch, digital artwork, or even a photograph that can be converted into a digital file. Once the design is finalized, it is transferred onto a thin, acid-resistant material called a resist. The resist is then applied to the metal surface, protecting the areas that are not meant to be etched.
Next, the metal is immersed in an acid solution that eats away at the uncovered areas, creating the desired design. The depth and intricacy of the etching can be controlled by adjusting factors such as the type of acid used, the temperature of the solution, and the length of time the metal is submerged. Once the etching is complete, the resist is removed, revealing the custom design on the metal surface.
