Transforming Aluminum Die Cast Parts into Functional Parts
With standard anodizing, the surface of machined and cut parts becomes rough due to anodizing treatment. However, with Vill12, implementation of a completely different treatment process generates a film structure with a roughness close to that of the pretreated surface.
Salt Spray Test (120 hours)
JIS1994 Value (Ra)
The film structure of Vill12 is overwhelmingly crack resistant in comparison to standard hard anodizing.
1 hour @ 400℃
Virtually no cracks were seen after 1 hour of thermal treatment at 400℃ due to superb heat resistance.
