The birotor wing thread guide is a critical core component on a winder. Its breakage can cause the winder to shut down and may even damage the traverse unit. Additionally, wear or malfunction of the birotor wing thread guide can lead to fluctuations in yarn quality. If such a fault is only discovered after spinning is completed, the entire batch of yarn can only be sold as Grade B product, resulting in economic losses for the filament manufacturer. Therefore, possessing high-quality traverse wing is a prerequisite for ensuring machine longevity and stable yarn quality.
Leveraging decades of R&D experience, Shengbang is committed to providing global customers with high-strength birotor wing thread guide solutions through continuous process optimization, fundamentally extending the service life of components and ensuring the high quality and stability of the yarn produced.
Furthermore, the ceramic insert developed by our expert team achieves extremely high fitting precision with the wing body and offers higher bonding strength compared to other ceramic inserts. This ensures the stable operation of the birotor wing thread guide throughout its entire service life. In terms of materials, our ceramic inserts are made from high-purity aluminum oxide, meticulously selected by our specialized technical personnel and fired at high temperatures. Its exceptional mechanical strength and bonding strength minimize the risk of fracture, ensuring that the production process operates smoothly and without risk even under high-speed, high-tension conditions.
Using our shift forks offers the following advantages:
• Excellent wear resistance
• Reduced yarn breaks
• Consistent yarn quality
• High-precision fit tolerances for extended service life
• Filament-friendly surface with optimized friction coefficient
• Wear- and corrosion-resistant, spin-finish oil-resistant
