Problem: Uneven coating
| Cause | Remedies |
|---|---|
| Grain size distribution of the powder is too coarse. | Contact the powder manufacturer. |
| Contamination | Contamination through “foreign” powder can be avoided by carefully cleaning the equipment. Different powders should not be mixed. |
| Coating too thick or too thin. | Adjust the powder output. |
| Workpieces too humid or too warm. | Check the drying, and temperature of the workpieces. |
| Depositions on the nozzles. | Maintenance! |
| Teardrops form when the powder ‘runs’. | Check the curing parameter / temperature. |
