一、涂装驻总装质量门——保险杠抽查情况：1、34周—35周共抽查GTL

1. The quality door of the general assembly of the painting-bumper spot check: 1. From <br>34 weeks to 35 weeks, a total of 884 GTL bumpers were spot checked, of which 14 were scratched on the surface, 40 were scratched on the edge, and 32 were scratched on the corners. The main failure points are concentrated on the edges and corners of the bumper. The overall failure rate is 9.8%, which is no significant drop from 33 weeks (including substrate problems). <br>2. The main reasons leading to the increase in bumper failure rate: 1) The bumper edge wrapping protection is not in place, caused by the interference of the equipment during the transfer process, 2) The substrate problem is not checked before spraying, and no problems are found in the first inspection after spraying. The second re-inspection problem was exposed;

1、 Spot check on the quality door bumper of the final assembly of the painting station:<br>1. From week 34 to week 35, 884 GTL bumpers were randomly inspected, including 14 surface scratches, 40 edge scratches and 32 corner scratches. The main failure points are concentrated at the edges and corners of the bumper, and the overall failure rate is 9.8%, which is not significantly lower than that in 33 weeks (including substrate problem).<br>2. The main reasons for the increase of bumper failure rate are as follows: 1) the packaging protection at the edge of the bumper is not in place, which is caused by the interference between the transfer process and the appliance; 2) the substrate problem is not investigated before spraying, no problem is found in the primary inspection after spraying, and the problem of secondary re inspection is exposed;<br>

I. Spot check of quality door of painting station and final assembly-bumper: 1. A total of 884 GTL bumpers were randomly selected from 34 weeks to 35 weeks, including 14 scratches on the surface, 40 scratches on the edges and 32 scratches on the corners. The main failure points were concentrated in the edges and corners of bumper, and the overall failure rate was 9.8%, which was not significantly lower than that in 33 weeks (including substrate problems). 2. The main reasons leading to the increase of bumper failure rate are: 1) inadequate protection of bumper edge package, resulting in interference between transportation process and appliances; 2) failure to investigate substrate problems before spraying, no problems found in primary inspection after spraying, and exposure of secondary re-inspection;
