QGMA series overhead rail shot blasting machine is suitable for  iron castings, steel casting, forging and stamping workpiece cleaning, particularly suitable for forging, casting workpiece cleaning, to remove the adhering sand, rust, scale, dirt of workpiece surface, make the workpiece presents clean surface, eliminate the internal stress of workpiece, improve the fatigue resistance, increase the workpiece painting adhesion, and eventually to improve workpiece surface and inner quality.As a rule, overhead rail shot blasting machine is offered either for batch and continuous processing.

Working Principle

Put the Work pieces hanging directly from the running gear’s rotating hook. An automatic feed mechanism then advances the work pieces to the blasting position. After the blasting program begins, the machine door is automatically closed and electro-pneumatically locked. As the work pieces rotate, they are blasted at blasting station according to the pre-set blasting times. Upon completion of the blasting cycle and after the turbines have come to a complete stop, the machine door opens automatically and the suspended work pieces out of another door. The next workpiece continues to cleaning like this. Form a continuous cleaning process.

Suitable Workpiece

Castings, forgings and steel structure, automobile parts, tractor parts, diesel engine, motor, valve, and the workpieces which having complicate surface and inner cavities such as cylinder blocks, engine covers and motor cases.


  • Removal of moulding sand
  • Removal of mill and forge scale as well as rust
  • Removal of burrs and scales
  • Increase of surface roughness
  • Shot peening to increase fatigue strength
