Reasons and solutions:
(1) caused by the uneven distribution of the powder paint. The solution is to improve the quality of the powder to ensure that the powder L, a, b or less and negative unity.
(2) caused by different curing temperatures. The solution is to control the set temperature and the conveyor speed in order to maintain the consistency and curing temperature and time stability of the workpiece.
(3) result in uneven coating thickness. The solution is to adjust the process parameters and ensure powder coating equipment running well in order to ensure a uniform coating thickness is consistent
