Mr. He is the owner of a vacuum cleaner manufacturer. Recently, the company has newly developed a small vacuum cleaner. The installed vacuum rotating brush needs anti-static functions. Through many tests, the vacuum rotating brush provided by the currently-available manufacturer has never reached the standard of Mr. He. The main reason is that the vacuum rotating brush filament is easy to deform and has poor recovery. Requiring the R&D department to replace the supplier again must ensure the quality and service life of the product.

Mr. He's research and development department finally found Guangzhou Aoqun after searching and verifying in various ways. After calling, I learned that Aoqun is a well-known domestic manufacturer of vacuum rotating brushes. For the products Mr. He needs, Aoqun can be customized. A detailed explanation is given to the phenomenon of deformation. Aoqun’s vacuum rotating brush is made of PA. After testing, its tensile strength value reaches 72N, and the friction of 120KM per hour is not deformed for 1 million times. Can provide relevant agency test report. Mr. He decided to let Aoqun make sample first. Two days later, Aoqun sent the prepared samples to Mr. He for testing according to the product drawings provided by Mr. He.

Half a month later, Aoqun once again received a call from Mr. He's company, saying: "The vacuum rotating brush has been tested by our company, and the quality has reached the standard and the performance is also very stable; after using it for half a month, the filament has not been deformed at all. The strength is also very good. "
