We're having good luck with anodizing large sheets and lengths of wire. However, we also need to do a lot of small parts. The only info I can glean from here is that it's very difficult. My questions are:

I have bought some anodized aluminum dog tags in the past in multiple colors, in lots of 1000. How are these done? It can't be too difficult because they are made in the US and are inexpensive. Would it work to put them on a pin rack? Do they have to be shoved onto the pins tightly enough so that they won't fall off? If so, wouldn't there be some un-anodized areas where the holes on the tags came into contact with the pins? We have examined them and the color is uniform - there is no apparent contact point. We have tried shoving the parts onto a length of wire, but they usually just fall off the wire as the anodizing process changes the size of the hole.

This question was asked a while back but did not get an answer. We have purchased large batches (pounds) of anodized aluminum jump rings (small metal rings for chain maille). The color is uniform, even on the ends of the rings were they are cut through. There is no apparent area of contact. How are they doing these?

thanks!!
