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.

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.

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.

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.

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.
