Normal-Pressure Sandblasting Machine | Jinwo, Qingdao, China

Jinwo's Normal-Pressure Sandblasting Machine is a compact, compressed-air blasting unit that throws abrasive onto a workpiece to remove rust, scale and old paint, deburr, matt the surface or prepare it for coating. It is available in manual and automatic versions.

It draws abrasive in by negative-pressure suction, so no high-pressure tank is needed and the machine is ready to use as soon as it is started. It suits small, lightweight, low-batch parts such as engine blocks, crankshafts and gears. Non-standard customisation is available.
