A brief description of the process of anodizing aluminum parts
The anodized aluminum parts process may seem a little complicated, but it is not. c & c machining is committed to providing customers with high-quality products in a timely, cost-effective manner. Of course, when it comes to machining high-quality parts and components, Hillside Custom Machining Welding and Fabrication LLC is a true leader in the industry. Here are some tips to help you get the most out of the process.
Purchase the right materials
Understanding the specific alloy is critical. The aluminum alloy chosen significantly affects the results of anodization. Different alloys have different compositions and have different effects on the anodizing process. For example, 6061 aluminum is popular for its quality, surface integrity, environmental resistance, and workability. Once the correct alloy is selected, it is important to use similar parts consistently. A supplier may have several types in stock. The quality of primary and secondary stock as well as production methods greatly affect the final product after anodization.
Don’t ignore chemistry
Ensuring high quality and reliable results during the anodization process requires precise control of the scientific aspects of each step. The anodizing method consists of several stages: cleaning, etching (pretreatment), anodizing, sealing, and rinsing between steps. Key controls at each stage include monitoring concentration, pH, time and temperature. While chemical suppliers specify parameter ranges for each substance, anodizers must study and test different conditions to determine the optimal ranges.
Controlled anodizing tank
Factors such as anodizing temperature, time, agitation and the quality of the cathode in the tank are crucial factors. These factors significantly influence the outcome of the part coating during the anodizing process. Effective anodizing technology requires careful control of the bath and a clear goal of obtaining a stable, high-quality coating. In addition to the specified chemicals in the tank, it is also crucial to adjust the rectifier (power supply) regularly.
Ensure proper surface preparation
Anodizing is different from other finishing processes. Every part of the aluminum surface must be fully prepared for anodizing. To ensure predictable results during the anodizing process, aluminum parts must be properly handled and maintained. Failure to remove oil, debris, and fingerprints can cause surface finish issues. Inspecting the material and ensuring these contaminants are removed is critical to increasing the likelihood of success.
