Polyurethane plastic polishing

Postby Lloyd » Fri Sep 18, 2015 5:11 pm

We manufacture a cylindrical cast polyurethane product, 9-inches in length and varying diameters from 7/8" up to 1-1/2", shore hardness of 80D. We are presently hand-polishing these on a buffing wheel to obtain the shiny finish needed. The buffing can take from 5 to 15 minutes per piece. We are looking for a more automated process; both vibratory tub and centrifugal barrel finishing have been suggested, but the machinery for the later is out of out price spectrum. We are also thinking about a plain rotational barrel system, which would be less expensive or even possibly DIY built. We are looking for suggestions for both machinery and media/compounds that would work for us.
