About Us

Shanghai Huanlei Filament Co., Ltd. was established in 1991 with the vision of Mr. Guo Zhaolei to become one of China's leading filament manufacturers. Our filaments are produced using state-of-the-art equipment and advanced technology.

Each filament is carefully extruded through a multi-stage quality control process, ensuring consistent, high-quality output. We operate two workshops—one in Henan Province and one in Shanghai—with 120 employees and 23 technicians across 20,000 square meters of land.

Recently, we expanded into India, forming a strong partnership with a leading brush manufacturer and establishing GUO TECHNO FILAMENTS PVT. LTD. Our Indian facility spans over 4,000 square meters with an annual production capacity of 3,000 tons, equipped with cutting-edge technology to meet global demands.
