Surface Finishing：What is anodizing?
Anodizing is an electrolytic process that creates a durable, corrosion-resistant oxide layer on the surface of aluminum (and other non-ferrous metals like titanium). This layer is integral to the metal—unlike paint or plating, it won’t peel or chip—and can be dyed in vibrant colors for aesthetic or functional purposes.

Some common anodizing Color
Anodizing alone cannot conceal tool marks, so for cosmetic parts during processing, we typically need to confirm whether sandblasting should be carried out in conjunction with anodizing.
This is especially true for natural anodizing—differentiation can only be made by subtle details, as the finish typically has a distinct luster compared to the base metal’s natural appearance after anodizing.
This is the finish after anodizing and sandblasting,BUT this is matte.
No specific notes, we typically apply a bright, metal-toned anodizing finish by default. Any special requirements must be clearly specified in the quotation.

Some applications
- (including sand blasting, glass bead blasting or dry ice blasting): Applied to create matte, textured finishes or for surface cleaning.
- I'm sure you've seen this surface before. Exactly, MacBook!
- Anodizing can also achieve gradient anodization effects, or create diverse surface finishes through exposure development and laser engraving.

CNC Texturing: First, fine knife patterns are carved into the metal surface using CNC machining.
Sandblasting: The surface is treated with high-pressure sandblasting to cover certain areas of the knife patterns, giving it a uniform matte finish.
Anodizing: Anodizing treatment is applied to enhance corrosion resistance while adding color.
This method combines the precision of machining with the matte texture of sandblasting, and the anodizing enhances durability and uniformity of appearance.
Certainly, masking techniques can also be used in anodizing to achieve diverse surface effects. The charm of CFM lies in its boundless creativity—and our machining team is committed to turning those ideas into reality.
The aluminum alloy shell adopts splatter anodization to achieve a unique artistic texture.
Splash-ink anodization is based on conventional anodization. By controlling electrolyte composition, current parameters, or adopting special coloring methods, it forms irregular "splash-ink" textures on the oxide film instead of a uniform single color.
