Powder consumption in powder coating: causes of increased consumption and optimisation options
Excessive powder consumption in powder coating can lead to increased operating costs and inefficient processes. It is therefore crucial to identify the causes of high consumption and take appropriate countermeasures. Based on the recommendations of GEMA, we present common causes and optimisation options below.
1. Inadequate recovery systems
If the recovery system is not working optimally, valuable powder is lost. Recommendation: Regularly check the filters and cyclones of your system and ensure that they are working efficiently.
2. Incorrect application settings
Inappropriate application parameter settings can lead to increased powder consumption. Recommendation: Optimise the voltage, powder flow and distance to the workpiece surface in accordance with the manufacturer's specifications.
3. Unfavourable workpiece geometries
Complex geometries can increase powder consumption because more powder is needed to reach all areas. Recommendation: Use suitable guns and nozzle systems that are designed for complex shapes.
Conclusion
By identifying the causes of increased powder consumption and implementing targeted optimisation measures, you can increase the efficiency of your powder coating system and reduce costs.
