blasting machine 7

Process parameters affecting blast quality

  • Initial condition of the component – material and contamination
  • Velocity of abrasive
  • Size (and shape) of abrasive
  • Hardness of abrasive
  • Blast wheel location
  • Travel speed of part through the machine (cycle time / exposure time)

Follow the path of abrasive:

  • Regular inspection is essential
  • Commonly blamed on the manufacturer
  • Quality of machine manufacture (cabinet design, lining etc.) does play a role
  • Common issues: leakage, noise, media consumption
  • Machine designs / controls are not intuitive to prompt maintenance

Saves on operating cost if taken seriously
