Hollow fiber membranes are vital in various industries, including water purification, gas separation, and hemodialysis. As the demand for these membranes continues to grow, scaling up production becomes essential. However, scaling up involves several technical and operational challenges. In this article, we will explore the key strategies and technological advancements needed to successfully scale up hollow fiber membrane production, focusing on efficient and cost-effective methods that maintain quality and environmental compliance.
Current Production Challenges
Cost of Raw Materials
The cost of raw materials is a significant factor in the production of hollow fiber membranes. High-quality polymers such as cellulose acetate, polyethersulfone, and polysulfone are crucial for producing robust and effective membranes. However, these materials can be expensive, and price fluctuations in the raw material market can impact overall production costs.

As a core component of environmental membrane production equipment,hollow fiber spinneret innovation has become a pressing industry priority. Legacy designs suffer from performance shortcomings that depress throughput and impose heavy maintenance burdens on manufacturers.
Before 2017, Shuiyi Group was troubled by two major issues with conventional hollow fiber membrane spinnerets
In NIPS and TIPS ultrafiltration hollow fiber manufacturing, the spinneret is not just a “die with holes.” A membrane spinneret must co-extrude polymer dope and bore fluid with strict concentricity, maintain a stable flow field through multi-hole distribution, and preserve a controlled thermal–mass transfer history to form a uniform lumen and selective skin. Regular textile spinnerets, by contrast, are optimized to produce solid filaments with comparatively broader tolerances and simpler flow control. Understanding these differences prevents misapplication and protects yield, uniformity, and membrane performance.
China TRUSTECH today announced that it has been granted a patent for an enhanced hollow-fiber membrane spinneret that solves longstanding mechanical-strength limitations in conventional hollow fibers. By introducing an integrated braided-tube channel and precision fluid-control architecture, the invention provides critical process capability for producing braided-tube–reinforced hollow-fiber membranes used in high-pressure water treatment and specialty separations. As a China leading membrane spinning machine and hollow fiber membrane spinneret manufacture, TRUSTECH continues to advance the state of the art with production-ready, modular designs.
The hollow fiber membrane industry for water purification and wastewater treatment relies on stable, efficient NIPS wet spinning. Trustech’s FCT 6th Generation Spinneret is the core forming component designed specifically for wet-process NIPS. Building on Gen5 strengths—independent spinneret core, pinless structure, and high-precision forming—Gen6 adds structural innovations for multi-hole expansion and per-hole independent control, supporting 8, 12, 16-hole configurations. During spinning, each hole’s dope (membrane-forming feed) and bore fluid (lumen-forming) can be switched on/off and regulated independently, eliminating the traditional pain point of “entire line stoppage due to a single-hole failure.” This is particularly valuable under unstable materials or large process fluctuations, boosting productivity, reducing waste and labor costs, and enabling large-scale manufacturing..
Riding the wave of innovation driven industrial upgrading, TRUSTECH Technology has achieved another breakthrough in hollow fiber membrane spinneret technology. Its independently developed "Embedded Multiple Holes Hollow Fiber Membrane Spinneret" has been granted a national invention patent (Patent No. : CN20151078942.X). This patent, the result of years of technical accumulation, injects fresh momentum into the industry while reinforcing the company's leadership in the field.
The three day 2020 Shanghai International Aquatech successfully concluded on September 2. As one of the world's most influential water treatment exhibitions, this year's event showcased the latest technologies and products from across the globe.
In NIPS and TIPS ultrafiltration hollow fiber production, the “nozzle” is the spinneret plate: concentric inner (bore) and outer (dope) flow paths must be resistance-matched to co-extrude a stable lumen and selective skin. Flow resistance design, verification, and on-line control determine inter-hole uniformity, OD/ID stability, and morphology reproducibility.
Trustech has officially launched MEMTOOLS (memtools.cn), an online tool for R&D and production of hollow-fiber, flat-sheet, dual-layer composite, and multi-lumen membranes. It offers capacity estimation, reverse configuration checks, process parameter references, and spinneret selection to improve efficiency and reduce repetitive calculations.
