Anodised Aluminium is the best material in nameplate production
Aluminium is durable and lightweight metal.
Can be sheared, machined, embossed or hard tooled.
We use high-quality Anodised Aluminium sheets as a standard.
Anodised Aluminium has a protective aluminium oxide layer added using electrolysis. This process forms a hard anodised layer of Aluminium which offers superior heat, chemical and abrasion resistance. The anodised layer will accept pigments, integrating the graphics into the surface creating a superior nameplate.
Anodised Aluminium nameplates are in use in harsh environments, on household appliances, industrial machinery and equipment.
Important product information, safety warnings, awards and other products printed with photo-quality graphics on such anodised aluminium plates are always eye-catching.
Aluminium nameplates are commonly used in military, aircraft, marine, heavy construction, food service, manufacturing and industrial applications.
Under natural the conditions aluminium produces an oxide film protecting the underlying material. This process is optimised under technical conditions in an anodising bath, aluminium being the only material allowing anodising. The natural oxide film of an aluminium component is merely 0.1 – 0.5 µm thick, unaesthetic and has a low hardness. However, a technically generated anodised layer offers very specific properties as for its layer thickness and texture, density and optical homogeneity.
The anodised coating is grown in an electrolytic solution, e.g. in sulfuric acid. In an anodising bath direct current is passed through an electrolytic solution, the aluminium component to be anodised serving as anode. The cathodes are placed on the bath’s edges. The requested anodised Al2O3 coating is generated in an extremely complex electrochemical reaction. A rather thin but closed barrier layer forms in a first step. Nanopores emerge as the layer grows.
