Two-Tone Anodising

I'd like to ask if anyone has done any work on 2-tone (2 colours on the same piece) anodising on 6000 series Al? If so, what's the process sequence?

Thanks

Sir,

Yes.. this can be done.. my company, as well as others do this (sometimes we'll do 5-6 tones) unfortunately, these process take a lot of research and development, and cost quite a bit of money to perfect, so you won't find too many people willing to GIVE you the process. I suggest you just start playing around, and see what you can figure out for yourself.

You can put a masking ink onto the surface you want to cover. The dried masking ink coating can be peeped off easily to put a second color on. You can repeat this process to produce as many colors as you want. Please contact us if we can be of any help.
