Anodizing is an electrochemical process producing decorative and protective finishes on aluminum parts and products. Parts to be anodized are mounted on special racks that grasp, and allow a specified amount of electrical current to reach each piece.
Aluminum parts, require the natural oxides and oils to be removed prior to Anodizing therefore, parts must undergo a pretreat, usually involving a series of mild cleaners as well as an Etch solution or a Brite dip. The Brite dip will brighten the part to a brilliant shine, as the Etch will produce a clean, satin finish.
The Anodizing at QoS takes place in a solution of Sulfuric acid, which converts the aluminum to aluminum oxide. This aluminum oxide can be produced in thicknesses from as little as .0001” up to .003” thick allowing for enhanced durability.
Following Anodizing, the parts can be dyed using a wide variety of color dyes as well as metal ion impregnation to achieve an extensive spectrum of finishes. The parts are then sealed, locking in the desired color, and producing a high quality, durable finish
