Anodized finish is bad... unavoidable or result of shortcut?
Anodized finish is bad... unavoidable or result of shortcut?
(OP)
Hello all,
I recently got a part in from a reputable machine shop my company does a lot of business with. They had sent out a part to be anodized and the finish looks pretty awful. The shop owner called me up to tell me that it wasn't really anyone's fault (but mine, I suppose) because the part, which was only out for modification, had been anodized once previously (when it was made) so the second layer didn't turn out well.
I'm having a tough time buying that. We've had parts twice-anodized before and they looked fine; it looks to me like the anodizers cut corners.
See photo: What do you think?

Seriously, that fingerprint mark is evidence of poor cleaning and/or poor handling at some stage of the anodizing process.

Pure sloppy work in the cleaning.
