1. Pre-treatment
Sandblasting and sanding to ensure that the workpiece is free of oil and embroidery.

2 . Theoretical curing conditions of powder coating
A. Theoretical curing condition 130°C/20min. 160°C/15min. 180°C/10min. 200°C/5min.
B. Temperature is the actual temperature of the workpiece surface when spraying
C. Time for the powder in the workpiece surface heating time

3. Baking temperature and time of the workpiece
A. Baking temperature is not equal to the surface temperature of the workpiece
B. The workpiece surface cooling rate is inconsistent with the temperature change.
C. Baking temperature and time are determined according to the oven's heating capacity and the workpiece's thickness, and the workpiece must be evenly heated.
D. Recommended temperature 200-300°C, time 0.5-1hr

4. The actual temperature of the workpiece surface
A. Use an infrared temperature measuring gun to determine the workpiece surface temperature
B. High workpiece surface temperature is suitable for obtaining good leveling and high gloss coating

5. Powder starting curing temperature
The temperature of the preheated workpiece for spraying is the starting curing temperature, determined by using a temperature measuring gun.

6. Powder effective and invalid curing temperature
A. the actual temperature of the workpiece is more than 130 ° C are effective curing temperature conducive to complete curing.
B. If the actual temperature of the workpiece is lower than 130 ° C are invalid curing temperature, the coating will not be cured.

7. The adequate curing time of powder
A. When the powder is sprayed to the workpiece temperature naturally cools to 130°C, the time is adequate curing time.
B. Temperature changes significantly impact the workpiece insulation; theoretical curing time can only be used as a reference; the actual curing time depends on field experiments to determine.
C. can adjust the adequate curing time by adjusting the baking temperature.
D. Ensure that the sufficient curing time of the powder can ensure that the coating is completely cured.
