Vibratory finishing of ornamental pewter

We design and cast large quantities of pewter figurines, ornaments, etc. We are currently hand finishing using very fine scotch brite soft wheels, for a nice satin brushed look. This is time and labor intensive, and I would like to achieve this look mechanically. Any suggestions?

I have worked with a number of pewter companies and set them up with vibratory systems. Usually this is a 3 step process using 2 grades of plastic media then finishing with treated organic materials. If you want a mirror finish,we are talking about a 4 step process. If you have really rough sand castings this could be a 5 step process. This is all done in the same equipment, but media changes are required. If you send me your address, I'll send you some articles I wrote on the subject.

Try mass finishing. it can b done using a vibratory bowl with the right media and chemicals.
