Anodizing Of Computer Chassis

By Roy van Rivero


A computer chassis (or more commonly known as computer casing) is a material that plays an important to the computer industry. It serves as container to computer components that can be found inside a system unit such as the motherboard, hard drives, as well as the central processing unit (CPU). These components need utmost protection and a computer chassis that is of high quality can be a great help to achieve the needed protection from the harsh surrounding.

One effective way to increase the level of protection for the components that can be found inside a system unit or PC is to make its outer covering (casing) more sturdy and durable. This can be achieved through anodizing process or more specifically sheet metal anodizing. No wonder why many computer manufacturing companies consider computer chassis anodizing very useful to the industry, including those whose focus is PC assembly.

So, how anodizing process is carried out?

GMP Plating, Inc., a metal plating and anodizing company serving California, provides on its website a general idea on how anodizing process for sheet metals, which includes computer chassis, is carried out.

In general, sheet metal anodizing is carried out with the following process:

Step 1: Wrought alloys are cleaned by either through the use of a solvent bath or in a hot soak cleaner; they may be etched in sodium hydroxide or brightened in a mix of acids. The cleaning process is recommended in order to remove impurities, particularly the inter-metallic substances.

Step 2: The passing of a direct current through an electrolytic solution on the surface of the substrate, which causes the outer layer to grow; the action of the electrons leaving the circuit through the metal part makes a tough, corrosion resistant coating to build up.

Step 3: Further treatment may be carried out to enhance the 'aesthetic' feature of the finish (e.g. decorative dyes) as well as other procedure for a more improved performance.

Step 4: The sealing process is aimed to close the pores in the anodic substrate, which is essential to give the surface resistance to staining, abrasion, crazing, and color degradation.

One of the key factors that help improve your computer lifespan is to ensure that the outer covering - aka computer chassis - is of good quality. Therefore, you have to determine which computer manufacturing companies use better computer chassis, which can be achieved through anodizing. And, again, anodized computer casing can help improve the quality of the product as a whole.
