Anodisation
Choice of anodisation
The application, properties and appearance of the aluminium product have special signifi- cance in the choice of surface treatment.
Since surface treatment adds an extra dimen- sion to the product, the chosen treatment will help to give the product its own unique character and will affect the properties of the product.
The anodisation process
The method is an imitation of the natural protective process of the aluminium, but in the HAI process oxidation is performed quickly, in clean surroundings and is fully controlled. This process is called anodisation.
The process means that the protected surface becomes more fast to light, thicker and stronger. The protective layer is approximately 100 times thicker and therefore more durable compared with the natural process. At the same time it is corrosion resistant, dirt-repelling and electrically insulated.

Contact marks
Contact marks
The aluminium product is secured in a mounting frame using clamps before being surface treated by immersion in a processing bath. Inside the baths current is transferred to the product as part of the treatment and the clamps will therefore leave a non-anodised mark. Also known as contact marks.
The optimum positioning of the clamps is determined in collabora- tion with HAI, Where they will not be of significance to the final function and appearance of the product.
