Ma is a supplier for China CRRC. They require a large number of brush strip sealing systems. The brush strip sealing systems has been sent by the Qingdao company before. In order to reduce costs, Ma also found some manufacturers in Guangdong, but the quality of the brush is not stable enough to provide professional reports.

The requirements of Ma are that the brush does not lose filament, the flame-retardant performance is good and the GB/T8624 report can be provided. In response to the customer's request, AOQUN Ms. Chen quickly gave a reply. Miss Chen said: "AOQUN specializes in the production of brushes, strictly controls the quality of products, eliminates the filament loss of the brush, and cooperate with many brand customers of the rail transit industry such as CRRC, Faville, and Weiao with high quality. There are UL94-V0 flame retardant reports, as well as ROHS, SVHC, NFPA130 and other industry standard reports, which can be used with rail transit customers to conduct project bidding in China and abroad. Therefore, AOQUN has an absolute advantage in the production of brush strip sealing systems." After receiving the company information of Ma, Miss Chen added the watermark of the report to the Ma.

After receiving the report, the Ma immediately made a determination with the business colleagues. After confirming that the report was correct, Ma Gong told Ms. Chen: "We have seen your report. This is the 8624 report we need. After that, we will be able to place orders for you." Three days later, AOQUN received a 1000-meterbrush strip sealing systems order from Ma.
