Hollow Fiber Spinneret

Melt Extrusion Spinneret, also called melt Spinning Spinnerette is a core precision component in melt-spinning processes. It forces high temperature polymer melts (e.g., PET polyester, PP polypropylene, PA nylon, PI polyimide) through micro-fabricated orifices under high pressure,typically with diameters from tens of micrometers up to a few millimeters,to uniformly extrude continuous filaments, fibers, or films. Its design must address three key challenges: uniform distribution of the high temperature melt, precise shaping and control, and resistance to corrosion and wear.

Thermally Induced Phase Separation (TIPS) spinneret—also called a TIPS spinning spinnerette—is a core precision component in TIPS membrane and fiber production. It forces a hot polymer–diluent solution (e.g., PP, PE, PVDF, PES blends in high-boiling diluents) through micro‑fabricated orifices and annular channels under elevated temperature and pressure to uniformly extrude continuous filaments or hollow fibers. Outlet features typically span from tens of micrometers to a few millimeters, tailored to target lumen size, wall thickness, and permeability–strength requirements. Immediately downstream, controlled cooling/quenches trigger phase separation and solidification, establishing the membrane’s pore structure.

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.
