Huang Gong is an engineer of a sliding door manufacturer. During this period of time, the seal bottom of door brush wire used to seal and block dust under the door body was too hard, which not only scratched the floor but also increased the resistance, which made the sliding door work very well. It's not smooth, so Huang Gong has been trying to solve it. By chance, I learned about and consulted Aoqun through searching.

After learning about the situation, Aoqun’s business manager Wang contacted Huang Gong, and after further understanding Huang Gong’s requirements, he suggested: "The hardness of the seal bottom of door can be adjusted by changing the diameter of the brush wire. , The smaller the seal bottom of door, the softer it will be. Aoqun is currently able to achieve each φ0.08mm level.” Later, according to Huanggong’s specifications and dimensions, the seal bottom of door sample will be sent for testing within 3 days.

After receiving the seal bottom of door sample from Aoqun, Huang Gong immediately conducted a detailed test, and received feedback on the same day: "The test result is very satisfactory, the brush is soft and comfortable, and it is almost comparable to beauty brushes on the US market; The operation of the door is also very smooth and there is no resistance. Thanks to Aoqun for helping to solve the problem, and hope to reach a long-term cooperative relationship in the future.
