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.

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.

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.
