Mr. Shi is developing a cleaning machine for the needs of foreign customers. Because cleaning is involved, an FDA-registered brush disc seal industrial brush must be used. Mr. Shi thought it was a simple matter, but he found 5 brush manufacturers through the Internet. In the end, all the brush disc seals purchased failed to pass the US FDA registration and the sample delivery failed.

Through multi-channel inquiries, Mr. Shi finally found Aoqun under the introduction of a friend. Mr. Yin Shi’s project has been developed for a period of time. With the support of the company, Ms. Sun provided Mr. Shi with FDA-registered brush disc seal samples in two days.

One month later, Mr. Shi called and reported that the customer was very satisfied with the test results of the brush disc seal provided by Aoqun, and hoped that Aoqun could start mass production as soon as possible.
