Hello,
I recently received multiple parts with the same kind of defect after being treated with chem film and anodizing. I took a picture of it (please see below).
I am wondering what might have caused this "bleeding". This had also happened in the past, but the company doing the plating (chem film + anodizing) was never very clear on why this happened. Could anyone please offer a clue? The bleeding does not seem to cause any dimensional variation, but I am really bothered by the appearance of the part. I tried looking for explanations online but could not find anything.
Thank you.
