Jammed Boards and Conveyor Rail Wear | 19 June, 2008

Hi, I'm having issues with boards sticking/jamming along the line, as well as what seems to be excessive wear along the guide rails. The boards are an Alumina Ceramic material and the rails differ by machine, but include anodized aluminum, steel, delrin and UHMW. Does anyone have any suggestions as to alignment, hand-off gap and rail-width specifications?

Also, does anyone have experience with any other materials or coatings that would stand up well under these conditions?

Thanks, Steven

Hi Steven, Those types of substrates generally require special conveyoring for the reasons you stated. The best material would be hardened steel although you might be able to use hardcoated aluminum. The process is similar to anodizing but the finish is much harder.

Por-15 paint. Just don't get it on your skin or any surface you don't want coated.
