Wet Spinneret

Hollow fiber membrane spinnerets are the core components for producing hollow fiber membranes. Their structural design, performance, and manufacturing precision directly determine the fiber's concentricity, wall thickness uniformity, pore size distribution, mechanical strength, and separation performance.

Trustech FCT 5th Generation Homogeneous Membrane Spinneret is the core forming equipment developed on the Fast Change Technology (FCT) . Featuring a “split spin core + flow channel plate” architecture and a high precision monolithic core,Trustech spinning spinneret is specifically designed for producing homogeneous polymer membranes such as gas separation membranes, pervaporation membranes, and high precision filtration membranes which exhibit uniform structure without a pronounced pore gradient. Building on the FCT series’ core strengths of “high precision and easy maintenance,” spinneret structure and features are specially optimized to meet the stringent requirements of homogeneous membranes for feed uniformity, structural stability, and performance consistency. It is a key enabler for the large scale, high quality production of homogeneous membranes, achieving high homogeneity across holes and batches.

A Flat Sheet Membrane Casting System mainly consists of four core sections: dope preparation and delivery system, doctor-blade/casting system, phase inversion and solidification system, and post-treatment and winding system.. The flat sheet membrane casting equipment performance and stability determine the quality and properties of the flat sheet membrane. Leveraging 11 years of experience and R&D, Trustech has upgraded the SteadyiCore Ultra 2.0 Heating System, TitanMix Pro 4.0 Mixing System and StoutDrive 2.0 motor drive setup. These Trustech technologies precisely control temperature and heat transfer uniformity, thereby enhancing flat sheet membrane spinning machine stability and reliability, reducing setup time and production downtime, and increasing overall spinning efficiency by 4.7% compared with pre-upgrade levels.

TIPS (thermally induced phase separation) hollow fiber membrane spinning is a technique for producing microporous membranes via temperature change. The core principle is to dissolve a polymer at high temperature in a high boiling, low volatility solvent to form a homogeneous solution, then extrude it through a spinneret. During cooling after extrusion, the system undergoes liquid–liquid or solid–liquid phase separation, ultimately solidifying to form a polymer rich phase and a solvent rich phase. Subsequent extraction removes the solvent; the space previously occupied by the solvent rich phase becomes the membrane’s microporous structure.

NIPS hollow fiber membrane spinning is a process for preparing hollow fiber membranes via non-solvent induced phase separation (NIPS). The core principle is to extrude a polymer dope through a spinneret into a non-solvent coagulation bath, where solvent/non-solvent exchange drives polymer phase separation and solidification, forming a hollow structure with an asymmetric porous morphology. This process is widely used in water treatment, gas separation, and medical applications.
