TRUSTECH Unveils New Generation Hollow Fiber Spinneret at the 17th WATERTECH, Reshaping the Industry with Hardcore Technology
From June 4–6, 2025, the 17th WATERTECH CHINA opened at the National Exhibition and Convention Center in Shanghai. As a flagship event for the global water treatment sector, this year's show spotlighted green innovation under China's "dual carbon" goals, drawing more than 2,500 brands and hosting over 100 high level forums on trends across the value chain. hollow fiber spinneret and spinning systems leader TRUSTECH made a high profile splash with its 8th generation hollow fiber spinneret and end to end spinning solutions, showcasing the hard edged strength of Chinese high end manufacturing.
Leading brand sets a new bar with breakthrough technology
TRUSTECH Technology is China's only end to end manufacturer of hollow fiber spinnerets and spinning equipment spanning environmental water purification, gas separation membranes, and medical hemodialysis membranes. Its newly unveiled 8th generation spinneret reflects a decade of R&D, advancing materials engineering, precision manufacturing, and membrane compatibility.
The series features a proprietary multi layer flow channel design, protected by 40+ granted patents. It precisely controls inner diameter, wall thickness, and porosity, pushing filtration to the micron and even nanometer scale. Compatible with multiple polymers, the platform serves industrial wastewater treatment, drinking water purification, and hemodialysis.
On site, TRUSTECH live demo drew experts and buyers worldwide. The team simulated the spinning process to highlight its advantages. TRUSTECH hollow fiber spinneret technology addresses the long standing challenge of membrane consistency. Its precision manufacturing is now world class," said a water treatment engineer from Germany.
Technological moat and global reach
As lead drafter of the "Hollow Fiber Membrane Spinneret" group standard, TRUSTECH hollow spinneret and spinning machines technology has driven continuous iteration since launching its 5th generation model in 2016. By 2025, its portfolio spans municipal, industrial, gas separation, and medical applications, with rising share in China's high end market and exports to 39 countries—including Brazil, Singapore, and the United States—serving 634 customers. In medical and gas separation membranes, TRUSTECH is among the few domestic firms mastering core spinneret technologies for hemodialysis and gas separation, bolstering import substitution.
"We follow a pathway of turning technology into patents, patents into standards, and standards into international norms," a TRUSTECH executive said. The company invests 15% of revenue in R&D and has built a complete innovation chain from materials to pilot scale trials. This "hard core innovation" model has again earned it National High Tech Enterprise status, making it a Chinese calling card in hollow fiber spinnerets and spinning equipment.
Open collaboration to shape the future
During the show, TRUSTECH participated in multiple forums, holding technical dialogues on shared challenges such as zero liquid discharge and seawater desalination. Looking ahead, the company will use hollow fiber spinneret and spinning system technologies as a fulcrum to build an ecosystem spanning R&D, equipment manufacturing, and application services.
TRUSTECH strong showing underscores its leadership in high end separation membrane equipment and highlights the shift of China's water treatment companies from technology followers to innovation leaders. As "dual carbon" efforts deepen, TRUSTECH aims to help drive a global upgrade of the membrane industry—ensuring every drop of purified water shines with the light of technology.
