Anodizing (Anodic oxidation) is an electrochemical process in which an oxide (anodic) layer is chemically built on the surface of the metal. Now anodizing is a commonly used surface treatment, especially on Aluminum alloys for structural or architectural applications.

The anodizing process forms an oxide film, a hard, corrosion- and abrasion-resistant coating with excellent wear properties. This porous coating may also be colored using a number of methods, thereby enhancing its aesthetic value even as it protects the metal.

Anodized Aluminum is an important product for a number of industries, including aerospace and automotive manufacturers, as well as various sporting activities and most up-to-date electronic devices, like iPods.

Many acidic solutions can be used for anodizing, but sulfuric acid solutions are the most common. Chromic, oxalic, and phosphoric acids are also used in certain applications.

By US military standard MIL-A-8625, it simply divides anodizing into three categories:

Type I - Chromic Acid Anodizing

Type II - Sulfuric Acid Anodizing

Type III - Hard Anodizing (Hardcoat)

Each different kind of anodizing system has its own setup, condition and processes. By googling it, it’s not hard to find the answers. However, when it comes to industrial production scale with 200 Tons/month or more, you would probably find a trusted and experienced anodizing equipment manufacturer and supplier.

We are able to offer customers not only design but also a turnkey basis solution of anodizing equipment which including design, build, commission & transfer the technical know-how of anodizing technology and periodic maintenance as after sale service as well.
