冯

Inventor & General Manager: Feng Jian (冯健)

All 4 patents are credited to our General Manager Feng Jian, who personally led the R&D of these chain guide profiles between 2017 and 2019 based on a decade of field feedback from European and South American conveyor system operators. Every cross-section solves a specific real-world wear or alignment problem.
