Anodised coatings combine functional and decorative properties in a durable aluminium oxide layer. They reliably protect aluminium from corrosion, improve adhesion and increase wear resistance. Anodising creates surfaces that are both technically robust and visually appealing.
The most important points
- Anodising of aluminium using the GS process
- Dimensionally accurate anodising
- Various pre-treatments available
Examples of anodised precision components
Anodising expertise at Polymeca
The GS process, the direct current/sulphuric acid process, is the most widely used anodising process worldwide. Polymeca also uses this process. It combines protection, appearance and process reliability in a stable coating process.
The aluminium oxide layer produced in the GS-process offers a high level of corrosion protection, especially after the final sealing process.
Polymeca offers dimensionally accurate coatings with no dimensional change. This makes Polymeca particularly attractive for applications in precision mechanics and optics.
The excellent colouring options for the coatings, as well as various mechanical or chemical pre-treatments, create numerous possibilities for decorative applications. For example, the combination of glass bead blasting and chemical shining allows for the creation of elegant surfaces with a high-quality feel.
Facts about anodising
Pre-treatments
With chemical or mechanical pre-treatments such as
- Si-carbide blasting
- Glass bead blasting
- Sand blasting
- Shining
- Pickling
- Matting
we create surfaces with defined visual and haptic properties. This allows us to meet different requirements and customer requests regarding function, appearance and feel.
