[Example of solving anodizing issues] I want to eliminate the streak lines after anodizing.

Introducing the causes of line generation and solutions to challenges! If you prioritize appearance and aesthetics, we will suggest materials based on the areas you focus on!

We received an inquiry stating, 'After anodizing, several mm to over a dozen mm lines have appeared, and I would like to remove them.' The occurrence of such lines after anodizing is not due to the surface treatment but rather 'the material characteristics of aluminum.' When producing aluminum materials, a concentration gradient of Mg components occurs near the center, which solidifies last, leading to uneven distribution. This unevenness causes the streaky variations. This document introduces suggestions for those troubled by issues such as 'wanting to eliminate band-like lines after anodizing.' If appearance and aesthetics are a priority, we can provide recommendations starting from material selection based on the areas of concern. [Overview] ■ Inquiry: 'After anodizing, several mm to over a dozen mm lines have appeared, and I would like to remove them.' ■ Conclusion: While they cannot be removed, it is possible to make them less noticeable. ■ Causes: - Not due to surface treatment, but due to material characteristics. - Anodizing has the property of highlighting scratches and unevenness. - The same phenomenon occurs with anodizing, colored anodizing, and hard anodizing. *For more details, please refer to the PDF document or feel free to contact us.
