Our Story

Our journey began from the year 2001 with a focus on trade, laying a solid foundation in market insights and customer needs. Driven by the pursuit of independent research and manufacturing capabilities, we took a crucial step in the year 2010 by founding our first manufacturing facility—HANGZHOU KOSMA MEMBRANE TECHNOLOGY CO., LTD. This milestone marked our transformation from a trading entity to an integrated enterprise combining R&D, production and sales.

To keep pace with the growing market demand, upgrade production technologies and expand capacity, we further strengthened our manufacturing layout in 2023 with the establishment of our second state-of-the-art production base—ZHEJIANG JUNTIAN FILTER TECHNOLOGY CO., LTD. This strategic expansion not only enhances our production efficiency and product quality control but also enables us to provide more stable and timely supply services to global customers.
