Anodizing Of Computer Chassis

By Roy van Rivero


Computer chassis (aka computer case) has been very useful to the computer industry as it serves as a container to a computer most important parts or components. For instance it is where you can find the central process unit (CPU) which is usually embedded on a computer motherboard. Having said that, it is therefore imperative that a computer case is made up of sturdy, durable material to ensure that it can provide the necessary protection for the elements inside a computer.

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 done?

Here's a step-by-step guide on the general process involved in anodizing metal sheets (including computer chassis) as provided by GMP Plating, Inc. - a metal anodizing service provider headquartered in Morgan Hill, California.

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.
