The processing phases of aluminium anodizing<\/h2>\n\n\n\n

Davide Zanus, responsible for the plant and anodizing process in Anodica, explains the processing phases of aluminium anodizing.<\/h3>\n\n\n\n

I am often asked what aluminium anodizing<\/em> is. In order to answer this question exhaustively, I believe it is necessary to explain the whole process and its individual phases, in their order of execution within Anodica\u2019s anodizing department.<\/p>\n\n\n\n

My colleagues and I can almost call ourselves “alchemists\u201d, we bring aluminium \u201cto life\u201d, through a process that gives it gloss and colour. Anodizing a component is not just an electrochemical treatment: in fact, it is a more complex process that is divided into different phases. Let\u2019s see them in detail one by one:<\/p>\n\n\n\n

    \n
  1. Cleaning. <\/strong>Before being processed, the material is carefully cleaned. Indeed, it is impossible to obtain an excellent finishing result with dirty material.<\/li>\n\n\n\n
  2. Gloss. <\/strong>We work to change the brightness of the surface and to achieve the effect required by the customer.<\/li>\n\n\n\n
  3. Aluminium oxidation. <\/strong>A thin layer of aluminium oxide is grown on the machined piece. We use electricity in order to obtain the correct degree of oxidation.<\/li>\n\n\n\n
  4. Colour.<\/strong> After oxidation, the component is almost always coloured. Colouring is an activity that brings us very close to artists. The long experience gathered by Anodica allows us not only to maintain tight control over the whole process, but also to replicate the same colour on different batches.<\/li>\n\n\n\n
  5. Finish consolidation.<\/strong> The last phase of the anodizing process consists in the consolidation of the finish, which takes place through fixing and drying. It is precisely in this final phase that the aesthetic appearance of the manufactured article is fixed.<\/li>\n<\/ol>\n\n\n\n

    Up to now we have had a look at the steps in the aluminium anodizing process. But another question may spontaneously arise: What is anodizing used for?<\/em><\/p>\n\n\n

    The reasons why an aluminium product is subjected to the anodizing process are various, the most frequent however concerns aesthetics Anodizing is therefore carried out to reach a certain aesthetic effect and to make the material more beautiful.<\/p>\n\n\n\n

    Aluminium anodizing is carried out also for its improving effect on materials, in particular:<\/p>\n\n\n\n
