The Anodizing Process


 

Successful execution of the anodizing process is key to producing a high quality, long-lasting coating for your product. However, there is much more to the process than meets the eye.

1. Cleaning
To assure a consistent finish, it is very important to start with a clean product - which is why Pilkington has invested in a comprehensive pretreatment program.

Because cleaning is so critical, you should always confirm that this step will be included as part of the anodizing process. At Pilkington, your product is cleaned using one or more of the following methods:

  • ultrasonic vapor degreasing
  • acid wash
  • alkaline cleaning

2. Mechanical and Chemical Pre-Treatments
After cleaning, your product is pre-treated to achieve the desired degree of reflectivity. Again, the quality of your finish depends upon skilled execution of these pre-treatment techniques, which can be used to create three different finished looks:

  • bright dip (highly reflective, gloss-like finish)
  • satin (low lustre - the most common finish)
  • matte (flat finish)

3. Treatment
This is the step where your product is actually anodized. However, you should be aware that not all anodizing treatments are 'created equal'. To assure the very best in quality, Pilkington uses MIL-A8625 Type II and Type III certified treatments. Your anodizing options include:

  • standard sulfuric anodizing
  • hardcoat anodizing

4. Finish
During the last step of the anodizing process, the final finish is achieved through application of the following:

  • color dye
  • sealants
