Recently, Jianggong, a technical vehicle manufacturer, found Aoqun and asked if there was a weather seal brush sliding door. The reason is that there is a gap in the middle of the door of the frozen car, which makes the car's sealing effect poor, and it also causes the external sand and rain to enter the car and damage the goods. Jiang Gong wanted to try to use the weather seal brush sliding door to block it, so consult Aoqun for customization.

Ms. Chen, directly communicated with Jiangong on the specifications of the car door, the size of the gap and the effect to be achieved, and directly suggested: Use h-shaped aluminum profiles to install on both sides of the door, using φ0.3 filament is used to produce the weather seal brush sliding door to block the gap; in this way, the crossing of the two sides of the brush can achieve the effect of sealing and wind, sand and rain. This suggestion was also adopted by Jiangong, and samples were sent for testing on the third day.

After receiving the weather seal brush sliding door from Aoqun, Jiangong was very satisfied with the test results for 2 days. The sealing of the car has been greatly improved, and the threat of external sand and rain has been avoided. Jiangong decided to install weather seal brush sliding doors on all freezing vehicles.
