BULK ANODIZING ALUMINUM RIVETS

    accurate anodizing banner   

(1996)

I NEED INFORMATION DEALING WITH BLACK ANODIZING ALUMINUM RIVETS. HAS ANYONE TRIED BARREL ANODIZING ? AND IF SO, WITH WHAT KIND OF RESULTS ?

You can't exactly "barrel" anodize, Terry, because the anodized surface is non-conductive so you can't get current into the parts that way. You can, however, put the rivets in a basket, squish a top onto the basket to hold all the pieces tightly in position, and then anodize in bulk. There does tend to be a much greater problems with contact marks, but specialists in bulk anodizing know from experience how to avoid much of the problem.

Considering the millions of rivets and other tiny components that are anodized, someone should probably build a bandolier style anodizing machine, or other continuous anodizer --but I've never heard of one.

I finally got around to reading the Dec Metal Finishing.

I would be interested in knowing whether anodizing rivets is even worthwhile. I assume the black would remain, but inasmuch as rivets are deformed during installation, would any protective nature remain or be of value.

I suppose, using Ted's bandoleer-style device, only the heads would be anodized and therefore it would be a worthwhile operation.
