Recently, Mr. Jiang, a technical engineer from a special vehicle manufacturer, approached Aoqun and asked if he could provide brush door sweep white. The reason is that there is a gap in the middle of the door of the refrigerated vehicle, which makes the sealing effect of the vehicle poor, and also causes the external sand and rain to enter the vehicle and cause damage to the goods. Jiang Gong wanted to try to use brush door sweep white to block, so I asked Aoqun whether it could be customized.

Ms. Chen Aoqun, who is in charge of the reception, after communicating with Jiang Gong in detail about the specifications of the car door and the size of the gap and the desired effect, she directly suggested: Use h-shaped aluminum profiles to install on both sides of the car doors, and use φ0.3 Brush door sweep white is produced by wool to block the gap (horizontal installation requires a certain thickness to stand up); in this way, the cross of brush door sweep white on both sides can achieve the effect of sealing and blocking wind, sand and rain. This suggestion was also adopted by Jiang Gong, and samples were sent for testing on the third day.

After receiving the brush door sweep white from Aoqun, Jiang was very satisfied with the results of the 2-day test. The airtightness of the carriage has been greatly improved, and the threat of external wind, sand and rain has also been avoided. Jiang decided to install brush door sweep white on all refrigerated trucks, so he directly placed an order for 100,000 meters.
