Major defects in plastic secondary processing?

In plastic part secondary processing, major quality defects as below:

1.Painting: thin oil, less oil, frying oil, oil accumulation, dust spots, wrinkling of orange peel, polished mark, color difference, oil residue, etc.

2.Hot stamping: dust spots, wrinkles, dents, burnt, peel-off, and so on.

3.Screen printing/ti pad printing: ghosting, blurred fonts, lines without smooth, different font formats, color difference, and so on.

4.Flying oil: means the paint adhesion appears on the non-painting area, which is usually for the reason that the painting fixture and the product are not consistent in size. Besides, inappropriate fixture design or loose fixture not assembled in place will also lead to flying oil issues.

5.Oil accumulation: This means the spray is so thick that caused excessive paint accumulation. And the reason for this issue is spraying too much on the part. At the same time, it leads to wrinkle or orange peel on the part surface.

6.Color difference: is the deviation among the painting color, the model, and the color palette, which is because of the poor paint quality, improper paint ratio, or irregular painting movement.
