Anodizing over Anodize

2006

I have a hardcoated part that needs to have additional machining done to it. Can the part be hardcoated again without stripping?

Ouch, what happened to quality control?
I can be done, IF you have points of good contact. If the part is not dirty or oily and several other IF's. The quality of the hardcoat may be degraded. sizes may change more than you want. So, it depends on a great many factors that you have not mentioned. Would I bet my job on it, NO. Would I try to find a great anodizer that would try it on a few parts, Yes, if the price were right.

This question has been asked several times. The answer is dependent on whether or not contact can be made to the anodized part.
If contact can be made it might be possible to anodize machined exposed areas. I would only attempt this if stripping the entire part would take it out of tolorance.
