How long does it take to cool down after powder electrostatic spraying solidifies before the parts can be removed?
After the powder coating is fully cured in the oven, the cooling time before handling or removing parts typically takes **15 to 30 minutes** at room temperature. However, the exact cooling time depends on factors such as:
– **Metal Thickness & Mass**: Heavier and thicker parts retain heat longer and take more time to cool.
– **Ambient Temperature & Airflow**: A well-ventilated area speeds up cooling.
– **Desired Handling Temperature**: If parts need to be handled immediately, they should be cool enough to avoid damage or burns (typically below **120°F (49°C)**).
For best results, it’s recommended to let parts **cool naturally** rather than using forced cooling, which can cause stress in the coating and affect durability.
