Customer feedback there’s a little problem of V212 WGR ,especially the rear one, they found the glass was raised more slowly in 4S’s WGR than in CKD. We do many comparison tests ,including hardness 、 compression load of lip、 friction coefficient and glass sliding force . All these tests is designed by 4S, there may be some deviation ,but every test was done in the same condition, its data can reference. Total 3 type samples was tested: 1、4S ISIR profile 2、CKD profile 3、4S improvement profile (decrease hardness of lip ,only RC) V212后门导槽玻璃升降问题分析 analysis report for glass rising issue of V212 rear WGR 硬度测试：hardness test Cut this lip to test hardness Inspection Equipment Thickness measure equipment Test methods with flock (We use one piece with flock to test) Test methods without flock (We stack several without Flock pieces and make it higher than 6mm then test ) V212后门导槽玻璃升降问题分析 analysis report for glass rising issue of V212 rear WGR 79.5 79.3 79.3 4S(ISIR) Sample 3 74.5 73.1 73.2 CKD 72.4 73.3 73.7 4S (improvement) 75.1 78.8 78 4S(ISIR) Sample 2 77.5 75.4 75.5 CKD 78.8 80.3 80.3 4S(ISIR) Sample 1 Profile C With Flock 76.4 74.8 75.3 CKD 72.3 72.7 74.2 4S (improvement) 74.9 74.7 74.5 4S (improvement) 1 3 2 Sample Sample 6.9 The sample is not enough to make 3 samples 6.34 6.7 6.8 6.41 7.01 6.8 6.31 thickness 77.4 76.3 76.7 4S Sample 3 CKD 6
