· We further consolidate its quality by using advanced technology.

· Shanghai Trustech Technology Development Co., Ltd. has improved customer friendly degrees and enhanced brand reputation over the years.

Main structure and mechanism 

  Split design: decouples the spin core from the flow channel plate; no locating pins; quick removal and installation like screwing in a bolt.

  Monolithic high precision spin core: one-pass machining of critical geometries of spinneret; machining accuracy up to 0.002 mm and concentricity of 0.003 mm; bore needle resists runout and is less prone to damage.

  Iso-pressure distribution and flow straightening: multi-stage damping chambers with equal resistance distribution reduce pulsation and inter hole flow deviation, ensuring a consistent annular gap shear field.

  Optimized orifice: micro-cone + cylindrical hybrid outlet with chamfers and mirror polishing to minimize shear discontinuities and filament hang up, supporting a wide process phase inversion window.

 Multi-hole modularity: supports expansion to 8/12/16/20/32 holes;

symmetric layout and optimized thermal paths reduce the impact of thermal

drift and assembly stress on uniformity.

The Advantages of Trustech FCT Spinneret

The spinneret design covers a wide dope viscosity range, offers strong versatility, high spinning stability, and effectively reduces issues such as filament breaks.

  Modular Design with Separate Spinneret Core and Flow Channel Plate:

No positioning pins needed, making assembly and disassembly as simple as using a screw.

  Integrated Spinneret Core:High precision and good concentricity.

  Robust Needle Design:The Bore liquid needle is not easily damaged.

  Easy Cleaning and Maintenance:User-friendly cleaning and maintenance ,friendly for non-professional operators

  High Reliability:Stable and consistent performance.

  Extended Service Life:

Longer operational lifespan.

Suitable Materials

PVDF (Polyvinylidene Fluoride), CA (cellulose acetate), PVC (Polyvinyl chloride), PES (Polyethersulfone), PSF/PSU (Polysulfone), PA (Nylon, Polyamide), PAN (polyacrylonitrile)

FCT Design  FCT

We can offer FCT designs that allow the spinneret core to be removed, replacing conventional designs where each spinneret hole cannot be independently replaced or disassembled. If one hole has a quality issue, the entire spinneret traditionally needs repair or scrapping. Our FCT spinnerets are independently designed so each hole can be individually replaced if needed. The FCT 6th-generation spinneret enables independent on/off control of the dope feed for each spinneret core, and the 8th-generation FCT spinneret cores can be changed online within a few minute down to 50 seconds when problems occur,to ensure continuous production without downtime.
