Problem: Powder depositing on an object
| Cause | Remedies | |
|---|---|---|
| Total air setting too low. | The ideal air volume should be in the region of 4 - 5 Nm3. | |
| Fine grain powder / powder with poor flow properties. | Using a powder hopper with fluidizing air, and vibration will help. | |
| Short term, high compressed air consumption can cause pressure fluctuations. | Fitting a larger compressed air reservoir directly before a high air consumption position will solve this problem. | |
| A too small cross-section or too small radius in the powder hose line up. | Radius must be at least 150 - 200 mm. | |
| A poor ratio between fresh powder and recovered powder. | Use an automatic fresh powder feed. | |
| Too high / low output | Adapt to the coating parameters. | |
| Contaminated injectors | Use an automatic fresh powder feed. |
