Anodized | Surface Finishes for Metal and Plastic Parts

Anodized

Description

It creates a corrosion-resistant finish. Parts can be anodized in different colors—clear, black, red, and gold are most common—and is usually associated with aluminum.(Note: 1.There will be a certain color difference between the actual color after anodizing and the above color board. 2.Rack marks are inherent to the anodizing process. When engineering a part that will be anodized, you'd better identify where the part will be racked. Typically, the racking location is chosen to minimize the visibility of the mark after the part is assembled.)

Design considerations for Anodized

Ensure that the material being anodized is compatible with the process. Some materials may not be suitable for anodizing, and different materials may require different anodizing parameters.
Ensure that the surface is properly cleaned and prepared before anodizing to ensure that the process is effective.
Depending on the application, the surface may need to be cleaned after anodizing to remove any debris or particles generated during the process.

The Justway Anodized process

The process requires careful control of the anodizing parameters to achieve a uniform and attractive finish. The resulting finish is durable, long-lasting, and has a high aesthetic appeal, making it ideal for applications in the automotive, aerospace, and consumer electronics industries. Let’s break down the basic steps for Anodized a part:

The surface is cleaned and prepared to ensure that it is free of dirt, oil, and other contaminants that could affect the anodizing process
The material is immersed in an electrolyte solution and an electrical current is applied
The anodized surface is allowed to dry and cure
The surface is inspected to ensure that it meets the desired specifications for color and texture
