Recently, the technicist Jiang of a special vehicle manufacturer found AOQUN, asking if there is a dust strip brush. The reason is that there is a gap in the middle of the freezer compartment door, which makes the compartment has bad sealing effect, and also causes the external wind and rain to enter the compartment and cause damage to the cargo. Jiang wants to try to use the dust strip brush to block, so ask if the AOQUN can customize.

Mr. Chen, who is responsible for the reception, communicated with Jiang in detail about the specifications of the compartment door and the size of the gap and the effect that needs to be achieved. It is directly recommended to use the h-shaped aluminum profile to be installed on both sides of the door, using φ0.3 mm filament to produce the dust strip brush to block the gap (the lateral installation requires a certain thickness); thus the crossover of the two sides of the brush can achieve the effect of sealing and blocking sand and rain. This proposal was also adopted by Jiang.

Upon receiving the test results of the dust strip brush of the AOQUN, Jiang was very satisfied with the test effect. The sealing performance of the carriage was greatly improved, and the destroy of external wind and rain was avoided. Jiang decided to install the dust strip brush on all the refrigerated trucks, so the order for 10000 meters was placed directly.
