Cause | Correction |
Particle size distribution of the powder is too coarse. | Contact powder suppliers. |
Contamination. | Contamination by foreign powder can be avoided by careful cleaning of the plant. In addition, different powders should not be mixed. |
Too high or too low film thicknesses. | Adjust powder output. |
Too wet or too hot workpieces. | Check drying and temperature of the workpieces. |
Powder deposits accumulate on nozzles. | Maintenance! |
Drop formation occurs when the powder flow is too strong. | Verification of the voltage and the distance to the workpiece, or the addition of thixotroping agents can help. |
