Claudia from India is the purchaser of the train door. She sent us an e-mail. "I am going to bid for a large government project. The flame retardant requirements for the brush are very high. There are several samples available from several supplier, but couldn’t reach the flame retardancy standard. We have found that your company has cooperated with many train door suppliers on the Internet. I believe you can help me provide VO-grade flame-retardant strip brush sizes."

AOQUN's senior business Lisa told Claudia that our AOQUN has been producing brushes for more than 11 years and has been cooperating with many well-known brands in the world, such as Favilley, China CRRC, etc., we supply strip brush sizes to them. They have very good feedback on the flame-retardant effect of our company’s product. Our flame retardant effect reaches the UL-94 flame retardant certificate which has been tested by the third party. Claudia asked us to send samples and provide test reports. After 5 days, Claudia replied to our Lisa: "I am very satisfied with the samples of your company. I have submitted the samples and materials for bidding. It is expected for the results within 1 week, and I will tell you the results."

Half a month later, Claudia sent an e-mail saying "Thank you AOQUN. We have win the bid with your strip brush sizes. I am currently pre-determining the specifications. I will send you the order information later."
