Trustech's 9th-Generation Hollow spinneret Debuts at the 18th Shanghai International Water Exhibition
From June 9 to 11, 2026, the 18th Shanghai International Water Exhibition (WATERTECH CHINA 2026) grandly opened at the National Exhibition and Convention Center (Shanghai, Hongqiao). As the world’s largest and most influential annual event in the water treatment industry, this year’s exhibition brought together more than 2,500 domestic and overseas brands and attracted about 100,000 professional visitors from China and abroad. It comprehensively covered core fields such as membranes and water treatment, environmental water treatment, and smart water services. More than 80 high-level forums held during the same period gathered over a thousand industry experts to deeply decode cutting-edge trends along the global water treatment industry chain.
As a leading player in the field of hollow fiber membrane spinneret, Trustech made a high-profile appearance with its new FCT 9th-generation hollow fiber membrane spinneret and its latest full-scenario solutions, including hollow fiber membrane spinning machines and RO flat-sheet membrane casting equipment. By empowering the global clean water cause with innovative technologies, Trustech once again demonstrated the hard-core strength of China’s high-end manufacturing.
Leading Brand Showcases Innovative Technologies, Trustech Redefines Industry Heights
Trustech is the only domestic full-industry-chain manufacturer whose products span hollow fiber membrane spinneret, hollow fiber membrane spinning machines, and RO flat-sheet membrane casting equipment, and cover the fields of environmental water purification, gas separation membranes, and medical hemodialysis membranes. The newly exhibited FCT 9th-generation hollow fiber membrane spinneret condenses a decade of the company’s technological accumulation and achieves breakthroughs in material processes, precision manufacturing, multi-bore design for 5-core and 7-core membranes, and membrane performance adaptability.
This product series adopts a proprietary constant-pressure flow-channel structural design and builds strong technical barriers through Trustech’s more than 40 authorized patents. In addition to enabling precise control of hollow fiber membrane inner diameter, wall thickness, and porosity, it also boosts the spinning efficiency of single-hole multi-core fibers by 4–8 times. At the same time, Trustech showcased its latest designs, including a profiled plum-blossom-shaped spinneret and a triple-fiber reinforced spinneret, directly targeting the forefront of the industry’s latest developments.
At the exhibition, the demonstration devices at the Trustech booth attracted industry experts and buyers from around the world. The technical team explained the spinning processes of spinneret, hollow fiber membrane spinning machines, and RO flat-sheet membrane casting equipment, intuitively showcasing the leading advantages of the FCT products. Water treatment engineers from Germany, Russia, and India commented: “Trustech’s spinneret technology has solved the long-standing industry challenges of efficiency, precision, consistency, and maintenance. Its design and manufacturing capabilities have reached world-class levels.”
Technological Barriers and Global Layout: From Patent Matrix to Market Leadership
As the lead drafting organization of the group standard “Hollow Fiber Membrane spinneret”, Trustech has continuously led industry iterations since it launched the 5th-generation spinneret in 2018, and has successively developed the 6th through 9th generations of hollow spinneret. To date, its products have formed a full-scenario matrix covering municipal, industrial, gas separation, and medical applications. Its market share in China’s high-end segment has been repeatedly refreshed, and it has successfully entered 39 countries including Germany, Singapore, and the United States, serving 634 customers worldwide.
In the medical and gas separation membrane fields, Trustech is among the few domestic enterprises that have mastered the core technologies for spinneret, hollow fiber membrane spinning machines, and RO flat-sheet membrane casting equipment used in hemodialysis membranes and gas separation membranes, providing critical support for import substitution.
“We have always adhered to a development path of ‘patenting technologies and standardizing patents’,” said a Trustech representative. The company invests 15% of its annual revenue into R&D and has established a complete innovation chain from materials to pilot-scale trials. This “hard-core innovation” model has enabled it to once again be recognized as a “National High-Tech Enterprise”, becoming a “Chinese calling card” in the fields of hollow fiber membrane spinneret, hollow fiber membrane spinning machines, and RO flat-sheet membrane casting equipment.
At the same time, Trustech also unveiled its online auxiliary decision-support tool, the “Membrane Toolbox”. This Membrane Toolbox transforms more than a decade of the company’s spinneret R&D and process experience into interactive data models, providing a set of reference solutions for capacity estimation, R&D selection, equipment configuration, and process tuning in the production of hollow fiber membranes, flat-sheet membranes, dual-layer composite membranes, and multi-core filter membranes.
A Trustech representative stated that in the future, the company will take technologies related to hollow fiber membrane spinneret, hollow fiber membrane spinning machines, and RO flat-sheet membrane casting equipment as a fulcrum to build an industrial ecosystem of “technology R&D – equipment manufacturing – application services”, helping China move from being a “major user of membrane technology” to an “innovation powerhouse”.
The successful participation in this year’s exhibition not only marks Trustech’s leading position in the field of high-end separation membrane equipment, but also showcases the transformation of Chinese water treatment enterprises from technological followers to innovation leaders. With the deepening implementation of green development strategies, Trustech is using high precision spinneret technology as a lever to drive the upgrading of the global membrane industry, so that the purification of every drop of water shines with the light of technology.
