We've been looking into getting a Universal Testing Machine, and found that a company called TestResources has them for half of the base price of an Instron. No one I know has ever worked with them, so I feel a bit uneasy about it. Has anyone here used one or heard about them? Especially...
I spoke to an electropolishing professional, and I got the impression that the amount of material removed would be purely a function of the thickness of the metal layer, not the height of the asperities or the thickness of the underlying plastic. Therefore, plating then polishing would exactly...
Thanks for the feedback. The parts are printed. I don't have a spec for the roughness yet, but we may even like to use it for molding optical components if possible. I am also just personally curious about this process (plating followed be electropolishing) even if it turns out not to make...
I have some plastic parts with an inadequate surface roughness. My colleague had the idea to get them plated and then electropolished, to achieve a really smooth finish. Has anyone encountered such a plating-polishing process before? I've only found info on plating or polishing separately, and...
