Mr. He is the owner of a vacuum cleaner manufacturer. Recently, the company has newly developed a small vacuum cleaner, and the installed vacuum dusting brush attachment needs to be anti-static. Through many tests, the vacuum dusting brush attachment provided by the currently cooperated vacuum dusting brush attachment manufacturer has never reached the standard of Mr. He. The main reason is that the vacuum dusting brush attachment filament is easy to deform and the recovery is not good. Requiring the R & D department to replace the supplier must ensure the quality and service life of the product.

Mr. He's R & D department finally found Guangzhou Aoqun after searching and verifying in various ways. After calling, he learned that Aoqun is a well-known domestic manufacturer of vacuum dusting brush attachments. For the products of Mr. He needs, Aoqun can be customized. A detailed explanation is given to the phenomenon of deformation. Aoqun ’s vacuum dusting brush attachment is made of PA nylon material. After testing, its tensile strength value has reached> 72N, and the brush is not deformed after 120km / h friction. And can provide relevant institutions to test reports. Mr. He decided to let Aoqun cooperate with the proofing first for the test. 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 dusting brush attachment provided by your company 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. The resilience is also very good. Now it is decided to order 500 vacuum dusting brush attachments from your company for production. "
