Mr. Li, a customer of the barn door, contacted Aoqun to ask if there is a brush seal barn with a height of 120mm. Because Mr. Li’s recent order requires a brush seal barn with a higher height, the previous supplier sent several samples. The drooping is severe, completely affecting the seal. So Mr. Li thought of Aoqun and asked if Aoqun had made similar specifications.

I learned that Mr. Li’s company is a factory specializing in the production of barn doors. The 120mm high brush seal barn needed this time is a brush seal barn for export to Australia. It is required to not sag and leak light and has good resilience. The diameter of the filaments used in the previous brush seal barn was too small, and the bottom width of the brush seal barn was too small, which caused the brush seal barn to sag automatically if it was too high. In view of this situation, it is suggested that Mr. Li can change the bottom width of the brush seal barn from 4mm to 6mm; the diameter of the brush wire is changed from the previous φ0.3 to φ0.5; and it is matched with the M06 door of Aoqun Company. Side aluminum strips, so that the 120-high brush seal barn will be sagging. In order to ensure that customers can see the most realistic results, Mr. Jiang also sent a sample of 120mm high brush seal barn to Mr. Li that afternoon.

Three days later, Mr. Li received the sample and immediately asked to place an order for 500-meter brush seal barn, because after Mr. Li got the sample mailed by Mr. Jiang, he immediately felt that the quality of Aoqun was indeed different, and the sample did not appear to sag at a glance. So he was relieved to place an order for Aoqun.
