What causes marks to remain on the paint? Three methods to prevent fixture marks when hanging.
Hanger marks, gripping marks, exposed substrate. By specifying the contact position of the jig and managing conductivity, appearance defects and rework labor can be significantly reduced.
The recurring issue in visual inspections is always the same contact point of the jig. It is not due to the painting conditions, but rather the design of the hanging method. Appearance defects caused by the jig account for 20-30% of rework labor. ────────────── ■ Cause of Occurrence The contact areas of the jig do not receive paint, resulting in exposed substrate and differences in film thickness. When paint builds up at the contact points, conductivity decreases, and the adhesion efficiency of electrostatic painting also drops. ■ Truth There is often a lack of awareness that jigs are consumables. Hangers that are used continuously without being stripped create foreign matter and defects in the next batch. ■ Improvement Measures Fix the contact points to non-functional or hidden surfaces and specify them in the drawings. Determine the stripping cycle of the jig based on usage frequency and conduct regular inspections of conductivity. Please utilize the materials that summarize jig design and appearance standards.
