Hollow fiber spinneret plates are the core precision components in hollow fiber production lines, playing a decisive role in the formation, wall thickness uniformity, and dimensional stability of hollow fibers. Hollow fibers, widely used in water treatment membranes, medical dialysis filters, gas separation, and high-performance textiles, rely on high-quality spinneret plates to ensure stable production and consistent microporous structure—making the spinneret a key factor affecting the efficiency and functional quality of hollow fiber production.

Our hollow fiber spinneret plates are specifically designed for the characteristics of hollow fiber spinning processes, including melt spinning, dry-jet wet spinning, and solution spinning (for different polymer systems). Manufactured with high-grade alloy materials (such as corrosion-resistant stainless steel, hastelloy, and titanium alloy) that feature excellent heat resistance, chemical stability, and wear resistance, our spinnerets undergo ultra-precision machining and strict quality inspection to ensure high dimensional accuracy, smooth inner/outer hole walls, and precise concentricity of the core-sheath structure.

The optimized micro-orifice design of our hollow fiber spinnerets (including precise core diameter, annular gap, hole density, and flow channel distribution) ensures uniform polymer extrusion, minimizes die swell, and guarantees consistent hollow ratio and wall thickness—effectively solving common problems such as fiber collapse, uneven wall thickness, and low porosity in hollow fiber production. Additionally, the superior material properties enable the spinnerets to maintain stable performance under long-term high-temperature, high-pressure, or corrosive chemical working conditions, extending service life and reducing maintenance and replacement costs.

We offer professional customization services to meet the diverse needs of different hollow fiber production scenarios. Customizable parameters include:

• Bore diameter (0.1mm-2.0mm)
• Annular gap size
• Hole number
• Hole pattern (staggered, linear, etc.)
• Plate size
• Specialized mandrel designs (for multi-lumen fibers)

These can be tailored to match different polymer types (PVDF, PS, PP, PAN, etc.), production line speeds, and product specifications (microfiltration, ultrafiltration, dialysis, or textile-grade hollow fibers).

Our high-precision hollow fiber spinneret plates help manufacturers optimize production efficiency, reduce waste rate, and improve the separation performance and mechanical strength of hollow fiber products. Whether for small-batch customized membrane production or large-scale continuous textile lines, our products provide reliable core component support for your hollow fiber manufacturing, helping you gain competitive advantages in the market.
