Rubber Belt Blaster

ISTBlast Rubber Belt Blaster tumble blast cabinets deliver efficient, affordable batch processing, while automating cleaning, peening and finishing of small workpieces. With certain types of parts, no other finishing method can compare to these heavy-duty machines in terms of speed and quality results.

Easy to operate: simply load parts and set timer, then return later to unload perfectly cleaned or finished parts. To optimize finish on parts you can adjust time, blast pressure, media type, media flow, tumble speed and blast duration.

As parts tumble, three or more nozzles uniformly blast all exposed surfaces to deliver consistent finish automatically. Includes standard oscillating gun-mount to ensure maximum coverage of all parts.

Inside tumble cabinet, parts ride on thick rubber belt that is perforated to allow blast media to fall through. Interior of tumble-belt cabinet-blast enclosure is rubber-lined to withstand years of cleaning or high shot peening.
