Product Description
Detailed Specifications & Features
Product Overview
Carbon fiber spinneret plates are precision-engineered micro-perforated components specifically designed for the production of precursor fibers used in carbon fiber manufacturing. These critical components transform PAN (polyacrylonitrile) or pitch solutions into continuous precursor filaments through meticulously designed micro-orifices. As the heart of the precursor fiber extrusion process, our spinneret plates ensure consistent fiber diameter, uniform cross-section, and optimal mechanical properties in the final carbon fiber product.
Key Advantages
1. Precision Micro-Hole Engineering
- Ultra-Precise Hole Diameters: 50-200 μm range with tolerances as tight as ±1 μm
- Optimal Hole Geometry: Circular, trilobal, or custom cross-sections for different fiber types
- Superior Surface Finish: Ra < 0.2 μm surface roughness minimizes polymer adhesion
- Advanced Array Patterns: Concentric, hexagonal, or custom hole arrangements
2. Material Excellence
- Premium Platinum-Rhodium Alloys: Pt-Rh 90/10, 80/20, 70/30 compositions
- Specialty Stainless Steels: 316L, 254 SMO, and corrosion-resistant alloys
- High-Temperature Stability: Maintains dimensional integrity at operating temperatures up to 300°C
- Exceptional Corrosion Resistance: Withstands aggressive PAN and pitch solutions
3. Enhanced Production Performance
- Superior Fiber Consistency: Achieve diameter CV values below 3%
- Reduced Filament Breakage: Decrease breakage rates by 30-50%
- Increased Production Speed: Optimized flow channels allow higher throughput
- Extended Service Life: Platinum alloys provide 2-5 years of continuous operation
4. Advanced Manufacturing Technology
- Laser Micro-Drilling: Femtosecond and picosecond laser precision
- Micro-EDM Machining: For complex geometries and tight tolerances
- Precision Grinding & Polishing: Multi-stage surface finishing processes
