Last month, Mr. Zhang, who was doing the door business, called me. His engineering customers reported that the brush strip for bottom of door of a batch of wooden doors he had provided were easy to wear, short in service life. He hoped that I can use the brush strip for bottom of door to solve this problem for him to do the after-sales treatment for his customers as soon as possible.

I asked Mr. Zhang to provide me with the relevant dimensions of the wooden doors, and then designed a solution for the brush strip for bottom of door for him, because this PP/PA independently developed by Aoqun not only is heat resistance, aging resistance, corrosion resistance, and wear resistance is stronger, and the service life is longer. In terms of sealing performance, the general strip is only 40%, and AOQUN brush can reach 98.5%. It also has the function of sound insulation and cold insulation. At the same time, I sent a sample to Mr. Zhang.

After receiving the sample for 3 days, Zhang said that the brush strip for bottom of door was very effective after testing, which solved the after-sales problem for his engineering customers. Finally, Mr. Zhang ordered 500 brush strip for bottom of door, and he said that he will continue to place orders.
