I received a call from Ms. Liao a few days ago, saying that she has been complained by customers recently, saying that the brush dust seal supplied by Ms. Liao has been loosened or dropped obviously after being installed, and it does not meet the acceptance standards of the product, and often needs to be arranged. Workshop personnel went to the site to do rework, which seriously affected the production schedule. Ms. Liao was very upset and hoped that we could help her solve this problem.

It turns out that Ms. Liao’s brush dust seal just fits the aluminum profile. If the brush dust seal has a negative tolerance, there will be signs of loosening after installation. We have made appropriate adjustments to the bottom width and side height of the brush dust seal and increased the requirements for the hair thickness. At the same time, in order to prevent the brush dust seal from falling off, the two ends of the supporting aluminum profile were clamped so that there would be no The brush dust seal is loose or dropped. On the same day, we provided Ms. Liao with 4 brush dust seal samples.

Three days later, I received feedback from Ms. Liao, saying that their company’s technicians conducted repeated pull tests on the brush dust seal samples and found that there was no sign of looseness or falling, which fully met the customer’s acceptance criteria. Ms. Liao expressed her satisfaction and placed an order for 30,000 meters on the same day.
