When anodizing aluminium, dimensions play a major role; we anodize ensuring that final dimensions are achieved. Thanks to our many years of experience, we have a great deal of knowledge about the various types of aluminium and their specific anodizing characteristics. There are also various possibilities in the field of colour anodizing.
If an even greater wear resistance or a thicker anodising layer is required, hard anodizing can provide a solution. The product can also be colored and/or teflonised.
If colours are desired on the product, one can choose colour anodising. During this process optimal process control is crucial. Knowledge, experience and the right expertise are important.
During the colouring process, the product is first dipped in a colour bath before the pores are closed, by means of the sealing. After closing the layer, the colours are secured in the top layer.
During the electrolytic colouring process, the process takes place during the anodising process under voltage. The difference compared to organic colouring is that the colour layer is more wear-resistant. Different variables can be adjusted to create different colours.
The application of a chromating-conversion layer on aluminium is often carried out as a pre-treatment for varnishing. Another reason for choosing this treatment: the chromate layer is electrically conductive. ATM is specialised in Surtec-650.
The purpose of this process is to restore the oxide layer that provides corrosion protection. ATM can perform this process not only on stainless steel parts, but also on titanium.
