Etched nameplates are made with durable recessed images that are virtually impossible to damage or deface. The etching method uses a mordant, or an acid, to eat into the metal’s surface to create recessed designs in high detail.
Traditional etching uses a waxy substance, called an acid-resist, that can withstand the mordant being used to protect parts of the metal that are to remain uncut. The longer the metal plate remains submerged in the chemical being used, the more pronounced the recessed parts of the design will be. Once the desired level for the etched design is reached, the plate is then removed from the acid and neutralized. The acid resist is then removed from the custom etched nameplate and inking can be used to create colored designs.
Stainless steel, aluminum, brass and bronze are the most popular metals used in for etching projects. Etching is one of the most durable marking methods since the design uses acid to eat into the metal, making a permanent design that is easy to read. Custom etched nameplates are also a great option for plates that will frequently be exposed to harsh conditions.
