Blasting Efficiency Testing
Blasting efficiency testing compares cabinet type, pressure, nozzle size, abrasive media and cycle time using representative parts before equipment selection.
Why test before buying?
Catalog parameters are useful, but they cannot fully predict how fast a cabinet will clean your real parts. Corners, cavities, rust thickness, paint condition, base material and finish requirements all change the result. A short test can reveal whether a suction cabinet is adequate or whether a pressure cabinet will pay back through faster cycle time.
Testing is especially important when the next process depends on the blasted surface. Coating adhesion, cosmetic appearance, deburring and dimensional control all need a defined setup. Record pressure, media grade, nozzle size, nozzle distance, blast angle, total time and inspection result.
After the test, connect results back to the blasting cabinet buying guide and select the cabinet around proven parameters instead of assumptions. For deeper technical context, use the article detail page.
| Test variable | Example options | What to record |
|---|---|---|
| Media | Aluminum oxide, glass bead, garnet | Grade, mesh size, fresh or recycled condition |
| Pressure | 40, 60, 80 or 100 psi | Actual pressure under blasting load |
| Nozzle | 3.2, 4.8 or 6.4 mm | Bore size, material and wear condition |
| Distance | 100 to 200 mm | Operator distance and angle consistency |
| Result | Cleanliness, Ra/Rz, profile, appearance | Pass/fail criteria and cycle time |
