Research and Innovation
Material innovation and extreme Environment resistance
Feiyun Seals uses independently developed fluororubber (FKM) and hydrogenated nitrile rubber (HNBR), and achieves wide temperature tolerance from -40°C to +250°C through customized formulas, and optimizes chemical compatibility (resistance to fuel, acid and alkali), which increases the service life by more than 30% compared with traditional materials. The product has passed RoHS and REACH certification, taking into account high performance and environmental compliance, and meets the needs of demanding scenarios such as automobiles and chemicals.
Precision design and intelligent
manufacturing process Combining finite element analysis (FEA) with double-lip/multi-lip structure optimization, Feiyun TC oil seal achieves 15% reduction in friction loss and dynamic sealing stability. Relying on Swiss imported CNC molds and automated production lines, the dimensional tolerance is strictly controlled to ±0.05mm to ensure mass production consistency. Special working conditions can be customized with structures such as three lips (TC3) to adapt to the diverse needs of wind power, food machinery, etc.
We carry out 12 quality inspection processes from raw materials to finished products, pass high and low temperature cycle, dynamic sealing (10,000 shaft rotation simulation) and other tests, and meet ISO 9001 and TS 16949 certification. We provide 1,000+ standard sizes (such as 20x35x7mm, 50x72x10mm) and 48-hour non-standard customization services, and deliver samples within 7 days, helping customers quickly solve sealing problems and reduce downtime risks.
