Mr. Li contacted Aoqun Brush Industry by phone and asked Aoqun if there is a door auto sweep, because he had seen this type of door auto sweep used in foreign countries at the exhibition and found it very convenient and wanted to buy a batch.

After understanding Mr. Li's needs, Mr. Aoqun Chen proposed two solutions for Mr. Li according to the needs. 1. According to the samples provided by Mr. Li, the product is opened, but the mold opening time is long and the mold opening fee is required. The minimum order quantity is 10,000; 2. It is recommended that Mr. Li try the door auto sweep developed by Aoqun. The auto sweep has good flame retardancy, good tensile force, and easy installation; the important thing is that the door auto sweep of Aoqun has been mass-produced and is widely used on various doors, and users have always responded very well. Based on Mr. Li's situation, Mr. Chen recommended to use Aoqun's door auto sweep first, and for Mr. Li's size and length, he soon sent samples to Mr. Li.

Three days later, Mr. Li sighed after trying out Aoqun’s door auto sweep products: “Aoqun’s brushes are made very well, with novel styles and very suitable for our needs. We will use this door auto sweep in the future. Immediately afterwards, Mr. Li placed a batch order of 20,000 sets.
