Traditionally, it was difficult to anodize die-casting aluminium alloy ADC12 with a uniform film due to the influence of silicon in the component.
At Nihon Shinkan, we were able to produce a uniform anodized aluminium film by developing specialized alumite treatment liquid and conditions and introducing a dedicated ionizing production line.
Aims to achieve an anodized aluminium film thickness of 10μm.
The actual thickness of the anodized aluminium film is a very stable. (9 - 11μm)
Characteristics of our ultra-precision anodizing
1. Pre-treatment (heat treatment, acid treatment, etc.) of the material is not required.
2. Corrosion resistance is stable.
3. The thickness of the film, even when it is thick, is stable (eg, ±2μm when the thickness is 20μm)
