TRUSTECH Leads Release of Group Standard for "Hollow Fiber Membrane Spinneret "
A major industry standard has been unveiled amid rapid advances in hollow fiber membrane technology, injecting fresh momentum into the sector. Led by TRUSTECH and co-developed with several renowned membrane industry players, the group standard "Hollow Fiber Membrane Spinneret " (T/SHDSGY058 2022) has been officially released, marking a key step in technical standardization.
As China's only full industry chain manufacturer of hollow fiber membrane spinneret and spinning machines, TRUSTECH brings deep technical expertise to this standard setting effort. Covering product design, manufacturing processes, testing methods, and quality control, the standard establishes a comprehensive specification framework. It provides unified technical guidance for upstream and downstream stakeholders, addressing long standing gaps in standards and inconsistencies in product quality.
TRUSTECH's central role stems from sustained innovation. Departing from traditional straight needle pin insertion, the company uses ultra precision machining to achieve 0.002 mm machining accuracy and 0.003 mm concentricity—benchmarks at the international level. From its 4th generation hollow fiber spinneret in 2015 to its 9th generation product in 2022, TRUSTECH has driven iteration with breakthrough advances in every generation: the 5th generation independent core design cut maintenance costs by 80%; the 8th generation enabled 30 second, non stop core replacement; and the 9th generation further improved precision and multi orifice uniformity.
Powered by these advantages,TRUSTECH's hollow fiber spinneret serve environmental water treatment, medical hemodialysis membranes, and other fields, with over 90% share of China's high end market and a customer base of 634 worldwide. As a National High Tech Enterprise with 40 plus patents, TRUSTECH has provided robust technical support for standard setting—particularly as China's only mass producer of spinnerets for hemodialysis membranes and gas separation membranes—offering practical benchmarks for specialty membrane product specifications.
The new standard signals a shift to a more regulated and mature phase for China's hollow fiber membrane spinneret plate industry. TRUSTECH will continue to advance the sector through standards driven leadership, accelerating upgrades toward higher precision and performance and strengthening the global competitiveness of China's separation membrane technologies.
