The customer of vacuum cleaner part Mr. Yan needs to find a vacuum extension brush. The vacuum extension brush provided by the previous supplier has the problem of fading, so Mr. Yan is looking for a manufacturer that does not fade.

Mr. Yan's company is a brand manufacturer specializing in vacuum cleaner parts. It has high requirements for product quality. The color of the brush strips is absolutely not allowed. After understanding Mr. Yan’s needs, Mr. Aoqun Chen analyzed that Mr. Yan’s original top supplier must have used poor quality secondary materials for production, and the color will fade. So Mr. Chen sent samples of PP black straight brush wire and PA brush wire to Mr. Yan according to Mr. Yan’s drawing requirements, and suggested that Mr. Yan conduct a fade test on the vacuum extension brush sent by Aoqun to check whether Aoqun’s products are It also faded and told Mr. Yan: “Aoqun cooperates with a large-scale domestic brushing factory to strictly control the quality of materials. Substandard materials will never appear. Mr. Yan can be completely relieved.”

After Mr. Yan received the sample, after 3 days of testing, there was no fading. The stone in Mr. Yan's heart was finally put down. He contacted Aoqun and Mr. Chen happily said: "The vacuum extension brush produced by Aoqun is really different." On the second day, Aoqun received a batch order from Mr. Yan.
