5 Interesting Things to Know About the Creation of Etched Nameplates

Etched Metal PlatesAre you looking for a cost-effective nameplate design option? Need a durable nameplate to help promote your brand? Looking for a medium that allows you to create interesting designs that will make your tags stand out? Etching is the answer.

Etching is a marking method that cuts into the metal surface to create images or designs. Etching creates a premium look because of the dimension it adds to the design. Etched texts and images can withstand a number of chemicals and extreme conditions leaving the etching legible for a long period of time.

Etching Process - The graphics/design details are screen printed and applied to the surface of the metal. The screen has resist to protect the surface with design details. Parts without resin will be cut away during the process. It is important that the spacing has 010" allowance from each other. During the chemical bath, the enchant cuts away the surface of the metal but leaving behind areas that are protected by the resist. You have the option to fill the corroded areas with a colour for additional aesthetic value or keep the space empty. For additional protection, a clear coat is applied to the surface.

Etching Options - There are 2 etching process methods that you can choose from. These options are standard etching and deep etching. Standard etching has a durable finish that is ideal for industrial uses while deep etch yields a premium finish for a two-tone appearance with dimension. Standard etching provides etch depth ranging from 0.0015” to 0.003” while deep etching 0.005”.

Thickness of Metal - It is very important that the metal etching will be applied to is thick enough to properly complete the chemical process. The recommended minimum thicknesses of the metal are .018” and 0.023” for standard and deep etching, respectively.

Etchant Options - Etchant is the chemical that cuts into exposed parts of the metal and producing the etched design output. It is very essential that the etchant is compatible to the metal because metals react differently to various chemicals. For example, copper and brass metals are both compatible with ferric chloride while aluminium metals can be etched using hydrofluoric acid.

Type of Resist - Resist, commonly inks or tapes, protects the parts of the metal surface from the etchant. You need to cover your design on the metal surface to exclude the parts from being eaten away during the chemical bath. The areas with resist are protected and will remain untouched because they will not be affected by the etchant.
