Hollow fiber membrane spinnerets play a pivotal role in the production of high-performance membranes used across various industries, from water purification and gas separation to biomedical applications. In this article, we will delve into the key differences between custom and standard hollow fiber membrane spinneret specifications, providing you with a comprehensive understanding to make informed decisions.
Introduction
Hollow fiber membranes are essential in modern filtration and separation technologies, with applications ranging from water treatment to medical devices. The hollow fiber membrane spinneret is a precision device that extrudes polymer solutions to create hollow fibers that form the basis of these membranes. The design of these spinnerets is crucial, as it directly influences the structural and functional properties of the fibers, such as permeability and rejection coefficients.
In healthcare, where these membranes are used for hemodialysis and blood oxygenation, precision is paramount. For industrial applications like water purification and gas separation, the spinnerets need to meet stringent performance criteria. Let's explore the key differences between custom and standard hollow fiber membrane spinneret specifications.

For hollow fiber membranes used in environmental treatment, medical devices, and gas separation, the spinneret head’s length-to-diameter ratio (L/D) is a primary lever for stabilizing extrusion, controlling fiber morphology, and ensuring batch-to-batch consistency. This blog clarifies what L/D means in the context of annular spinnerets, why it matters, how it differs for NIPS vs. TIPS, and how to tailor it to application specific constraints. Trustech incorporates these principles into robust, maintainable spinneret solutions for demanding lines.
In a TIPS hollow fiber spinning line, the moment of truth arrives after the spinneret: the coagulation and extraction system converts a hot, homogeneous polymer–diluent stream into a dimensionally stable, porous fiber. Get this module right and you gain repeatable morphology, clean residual profiles, and lower lifecycle cost across environmental treatment, medical filtration, and gas-contacting applications. Trustech integrates this stage with recipe control and solvent-management options to keep quality and sustainability aligned.
In NIPS hollow fiber spinning for environmental filtration, medical dialysis, and gas separation, the moment a coaxial micro-jet turns into a stable, porous fiber is governed by the phase separation and coagulation module. Get this stage right, and you lock in pore architecture, cleanliness, safety, and long-run stability. Trustech integrates this module with upstream metering and downstream drawing so that morphology, purity, and sustainability are managed as one system.
From July 2 to 4, 2026, the 2026 (5th) China International Gas Separation Industry Conference, organized by DT New Materials, successfully concluded in Ningbo, Zhejiang. Nearly 300 industry experts and practitioners from universities and research institutes, engineering general contractors, equipment manufacturers, and raw material producers in the fields of membrane, adsorption, absorption separation, and MOF/COF/HOF materials gathered at the venue to jointly explore cutting edge gas separation technologies and pathways for industrial implementation.
In TIPS hollow fiber spinning, dimensional uniformity starts long before the quench. It is secured by a trio of front end modules that turn variable raw inputs into steady, shapeable flow: filtration and metering, nitrogen pressure stabilization, and the spinneret block. This article explains how each works and how to configure them so your line runs cleanly and repeatably across environmental treatment, medical filtration, and gas-separation applications. Trustech integrates these functions into recipe-driven, upgradeable lines to minimize drift and defects.
