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.

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.

A TIPS (Thermally Induced Phase Separation) membrane spinneret is the core component used for preparing polymer microporous membranes via the thermally induced phase separation method. Trusstech TIPS spinning spinneret is a hollow fiber spinning head specifically designed for the "high-temperature melt–cooling-induced porosity" route, used to produce microporous membranes from crystalline polymers such as PVDF, PP, and PE. Its structure and functions must simultaneously satisfy around-200°C melt sealing, rapid cooling induced pore formation, and controllable porosity. Its working principle relies on temperature changes to induce phase separation in a polymer solution, ultimately forming a membrane material with a microporous structure.

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. Its central objective in multi-hole parallel production is to stabilize outer diam

The FCT 5th generation MBR spinneret plate is a high precision, high efficiency core production component developed by Trustech on its independently innovated Fast Change Technology (FCT) for manufacturing hollow fiber membranes used in MBRs (membrane bioreactors). It is a revolutionary spinning spinneret whose core design philosophy is through a split, modular architecture to delivers exceptional ease of use, high precision, and long service life. It addresses the traditional problems of hollow spinneret plates such as complex disassembly/assembly, susceptibility to damage, and high maintenance costs, establishing a technological benchmark in the field of hollow fiber membrane manufacturing.

The FCT 6th generation spinneret plate is the core forming component for hollow fiber membranes, developed by Trustech based on Fast Change Technology (FCT) and designed specifically for wet-process NIPS (non-solvent induced phase separation) spinning.

Hollow fiber membrane spinnerets are the key parts for making hollow fiber membranes. The spinneret geometry, functional characteristics, and fabrication accuracy directly decide the fiber membrane's concentricity, wall uniformity, pore size distribution, mechanical robustness, and overall separation efficiency.

During the manufacturing of hollow fiber membrane, to ensure the precision and quality of hollow fiber, it is necessary to maintain accurate and stable transportation of materials. Gear metering pump features precise volume metering and stable low pulsation conveying functions, which allows it to be used for guaranteeing the quality of hollow fiber membrane and increasing the pressure of spinning pump so as to ensure efficient operation. Therefore, Trustech specially configures this metering gear pump to customers for improving product quality and production efficiency and thus reducing cost.

A sol - gel sintering spinning spinneret is a coaxial extrusion spinning assembly for inorganic/ ceramic hollow fiber membrane. The outer phase is a sol or organic–inorganic hybrid precursor, containing inorganic particles or precursor solution with organic binders/ porogens, while the inner phase is a supporting bore fluid which may be a coagulant, a nonsolvent, or an inert fluid. After shaping, the green fibers undergo gelation, solvent exchange, drying, debinding, and high temperature sintering, typically 400 - 1200°C, to yield dense or porous inorganic/ ceramic hollow fibers membrane such as alumina, zirconia, silica, titanates, and the approach is also applicable to metal/glass precursor systems.

A dry-jet wet spinning spinneret is the core forming component tailored to the Dry-Jet Wet Spinning process for producing hollow fiber membranes. THis spining spinneret primary function is to precisely co-extrude a polymer casting dope and a bore fluid through coaxial flow channels, so that the extruded "liquid filament" first passes through an air gap which calls dry zone for partial solvent evaporation and initial drawing, then enters a coagulation bath which calls wet zone for phase separation and solidification, ultimately forming hollow fibers membrane with specified structures and properties. The spinning spinneret must be designed to accommodate both "liquid filament stability in the air gap" and "initiation of phase separation in the coagulation bath,"acting as the critical bridge between dry state drawing and wet state solidification.

Dual layer dope spinneret spinneret, also called a composite membrane spinneret, is a key forming component used in membrane separation/filtration manufacturing. In a single co-extrusion step, it laminates two or more functional dopes into a prescribed layered architecture and shapes them through micron-precision orifices or slots into a layer-by-layer structured membrane. Its core role is to stably and controllably stack and form multiple fluid streams within a microscale flow space.
