At the beginning of last month, I received a call from Mr. Li, a purchaser from a door company. He said that his company focuses on engineering projects. Recently, one of their engineering customers reported a quality problem, that is, a batch of door brush guards that had been installed a year ago had shed hair, which affected the sealing and dust-proof function, and light leakage occurred. The original door brush guard supplier has switched to no longer operating door brush guard products, and no one has up after the sale, so this time Mr. Li came to our Aoqun, hoping that we can solve this problem for them.
After learning about Mr. Li's needs, I asked him to remove a door brush guard from his client and send it to me. After disassembling and observing, I found that the base of the door brush guard inside the aluminum strip beside the door has been rusted and corroded very badly, and the fastening force is greatly reduced. In addition, the door brush guard is opened and closed frequently in daily use, and the door brush guard is connected to the ground. Frequent rubbing causes the filaments fixed by pressing to fall off from the base relatively easily, and the arrangement becomes more and more uneven, gradually losing the function of sealing dust and preventing light leakage. Secondly, the bases of this batch of door brush guards use electrolytic plates, which have poor anti-rust function. It is easy to rust and corrode in places with high humidity such as bathrooms; stainless steel plates are the most suitable base. I suggest that Mr. Li's future door brush guard use stainless steel plate as the base, so that similar problems rarely occur again.
Finally, Mr. Li signed a cooperation agreement with our company and ordered 100 sets of door brush guards to Aoqun to replace the last batch of problematic door brush guards. Half a month later, Mr. Li said that the installation effect was very good, and his customers also affirmed their company's quick after-sales response. At the same time, Aoqun has also become the designated supplier of their company's door brush guard products.
