Hollow Fiber Membrane Spinneret
The spinneret is the core component in hollow fiber membrane production, directly affecting fiber concentricity, extrusion uniformity, and spinning stability.
It is widely used for manufacturing MF, UF, and NF membranes, applied in water treatment, hemodialysis, gas and liquid separation.
Designed with dual channels for dope solution and bore fluid (or nitrogen in thermal processes), it ensures precise flow control and stable fiber formation.
