Yifei Automation

Yifei Automation — now rebranded as Yifei Technology (翼菲科技, 06871.HK) — is a Chinese industrial robotics company founded by Zhang Sai, who started in 2013 in Jinan with three people and an 8-square-meter office, building one of China's first parallel (delta) robots from scratch . A FreeS Fund portfolio company since its 2016-era A round , it made its name by cracking benchmark manufacturing clients: most famously Lens Technology, whose first trial order demanded 2,500 glass panels loaded per hour within a 2×2 m² footprint with zero scratches — Yifei's engineers turned around a new design in two days and delivered two machines to Lens's Changsha plant inside the deadline, converting a 16-unit first order into tens of millions within six months . It later won accounts including Unilever, Dong-E-E-Jiao, Goertek, BYD, and Bloomage Biotech , raised a Series D in 2022 led by Primavera with CBC Capital and Tsinghua's venture arm following , and in 2023 restructured — spinning the standardized robot body business into "Yifei Robot" while keeping "Yifei Automation" as the custom-integration sub-brand under the unified Yifei Technology name, with robot bodies rising from 10% of 2023 revenue to 20% in 2024 . On May 18, 2026 it listed on the Hong Kong Stock Exchange as the first light-industry full-category robotics company under Chapter 18C, ranking as China's fourth-largest light-industrial robot and solutions supplier by 2025 revenue per its prospectus .
