Etched nameplates offer a more durable option to surface printing or even anodised text. Chemically etched nameplates offer a permanent marking solution for your products.
Etched nameplates are recommended for applications where the environment is particularly harsh such as off shore oil rigs, heavy engineering and the food processing industry.
The text detail can be chemically etched away from the surface of Brass and 304 or 316 Stainless Steel leaving an extremely durable nameplate.
The etched detail is achieved by silkscreen printing a chemical resistant coating onto the areas which are not to be etched. The sheets are then put through the etching machine which contains a mixture of Ferric Chloride and Hydrochloric Acid with water and the areas not covered by the resist are etched away to a maximum depth of 0.08mm. The sheet is rinsed with water and the resistant layer cleaned off. The etched nameplate detail can then be either left natural or paint infilled with a stove enamel paint and baked at high temperature.
For etched nameplates with multi coloured infill requirements this process is repeated for etch colour and it is worth noting that a minimum gap of 1mm would be required between the colours.
Various thicknesses of brass and stainless steel are available from 0.5mm to 2mm and we offer polished brass or polished, satin and brushed stainless steel finishes.
If required for outdoor applications etched brass nameplates can be over lacquered for added protection against the elements whereas the stainless steel needs no further treatment.
The etched nameplates are supplied cut to size with either fixing holes or a permanent self-adhesive tape to suit your particular application.
Should unique identification details be required, we can achieve this by laser marking or dot-peen marking each one of the finished etched nameplates with sequential numbers.
