Acid metal etching is a form of metal etching that uses acid to produce a depressed design on a metal plate by cutting lines through a protective coating and then applying corrosive acid that removes the metal under the lines. A broad range of metals can be used during the acid-based processes, such as stainless steel, copper, brass, nickel and silver alloy. Currently, using acid is the most common method for metal etching.
Photo etching, sometimes referred to as “metal chemical etching,” “chemical milling,” or "photochemical machining, is the most common acid etching process. During the process, the desired image is etched on the surface of the metal part via a photosensitive template. The piece is then exposed to an appropriate acid (or etchant) that removes a layer of metal in areas left unprotected by the template, after which the piece is cleaned and the photoresist template removed.
The acid used in the metal etching process is controlled in several ways. Most often, a hard, waxy, acid-resistant ground is applied to the plate. A design is scratched into the surface with a sharp point, exposing lines that are attacked by the acid. A soft ground is sensitive to pressure. Paper is placed on the part. A pencil is then used to make the lines of varying densities, which allows more or less acid through, depending on the pressure applied. Faux-bite results from small amounts of acid leaking through the ground, creating minor pitting and burning on the surface. It can be removed by burnishing, polishing or smoothing the surface.
Acid-etched metal products have several applications in many industries. In the automotive industry, brake rotors and fuel cell plates are made from acid etching. Another common application is within the sign and plaque industry. Other uses include jewelry production, etching for business cards, logo name plates, panel covers and promotional items, stencils for the woodworking and art fields, various metal industrial parts, and as a decorative finish on many metals. Acid metal etching allows a metal to meet weight demands, as well, by dissolving an appropriate layer of the surface.
