At Presto we take responsibility for all aspects of your project from submission of drawing to on time delivery of your components with a pristine finish.

We offer a range of finishes and the application of the product usually determines the choice of finish.

For visible parts where appearance is key aluminium lends itself to stylish finishes such as anodising. Durability is often a deciding factor particularly when parts are for outdoor use. When parts will not be visible and are for indoor use they can have a range of cost effective treatments such as Surtec 650, Alochrom or Irridite. Whatever your requirements we work with you to find the best solution for your component.

We have long established relationships with all our Finishing partners. They are the ‘best in the business’ within their particular expertise and work to the same high standards as we do.  We guarantee your CNC milled and turned aluminium machined parts will always be delivered to you with a pristine finish.

Anodising Aluminium

Anodising can only be carried out on aluminium and it is the most frequently requested finish by our customers. It is an electrochemical process that converts the metal surface into a decorative, durable corrosion-resistant anodic oxide finish and can be dyed in a variety of colours and finishes.

Anodising aluminium is accomplished by immersing the aluminium into an acid electrolyte bath and passing an electric current through the medium. A cathode is mounted to the inside of the anodising tank; the aluminium acts as an anode so that oxygen ions are released from the electrolyte to combine with the aluminium atoms at the surface of the aluminium part being anodised. In brief, aluminium  anodising is a matter of highly controlled oxidation which is an enhancement of a naturally occurring phenomenon.

Benefits of Anodising include:

Anodised Aluminium Panels

Bead Blasting and Graining

Paint Finishes
