Problems with the Powder Container in Powder Coating: Causes and Solutions
An efficiently working powder container is essential for consistent and high-quality powder coating. Issues in this area can lead to uneven coating thickness and surface defects.
Common Causes of Powder Container Problems
- Excessive fluidizing air pressure: Too much pressure can over-agitate the powder, resulting in uneven coating.
- Worn fluidizing plates: Over time, fluidizing plates can become partially clogged, impairing fluidization.
- Clogged ventilation: If the container is too far from the booth, ventilation may clog, causing overpressure.
GEMA Recommendations for Correction
- Optimize fluidizing air pressure: Adjust pressure so the powder “boils” lightly and evenly.
- Replace fluidizing plates: If wear is visible, replace plates to ensure proper fluidization.
- Position the container correctly: Place it as close to the booth as possible, with the shortest possible hose, which must be cleaned daily.
