A few days ago, I received a call from Miss Liao from Chengdu. Recently, she was always complained by the customer. After the installation of the brush strip for bottom of door supplied by Ms. Liao, there was obvious looseness and falling, which did not meet the product acceptance standards, often need to arrange workshop staff to go to the scene for rework, seriously affecting the production schedule. Miss Liao is very distressed, hopes AOQUN can help her solve this problem.

It turns out that Miss Liao's brush strip for bottom of door fits the aluminum profile. If the brush has a negative tolerance, there will be signs of looseness after installation. We made appropriate adjustments for the bottom width and side height of the brush strip for bottom of door, increasing the thickness requirement, and at the same time, in order to prevent the brush strip for bottom of door from falling, the two ends of the matching aluminum profile were clamped, so that the brush will not loose and falling. On the same day, we provided Ms. Liao with four samples of the brush strip for bottom of door.

Three days later, she received feedback from Miss Liao, saying that the technicians had repeatedly tested the sample of the brush strip for bottom of door 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 issued an order of 30,000 meters on the same day.
