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
