- Six-axis, SCARA and delta robot families cover welding, handling, painting and assembly.
- Integrated vision and force-control options for flexible automation.
Supply-Chain Analysis
- ESTUN's vertical integration of servo, reducer (partially) and controller is its moat against both foreign and domestic rivals.
- Harmonic/RV reducers are sourced partly in-house and partly from domestic suppliers like Leaderdrive and Shuanghuan.
- As humanoid demand grows, ESTUN's servo expertise positions it as a potential component supplier as well as a robot OEM.
Competitor Comparison
Versus SIASUN (新松): ESTUN focuses on standard industrial robots and servos, while SIASUN spans mobile and special robots. Verses foreign majors, ESTUN wins on price and local service, while trailing on brand in premium segments.
Global Benchmark
ESTUN is China's closest challenger to the global industrial-robot oligopoly of ABB, KUKA and FANUC. Per MIR Databank it took No.1 in China robot shipments in 2025 (10.6% share) — the first time a Chinese brand has overtaken foreign incumbents in the domestic market. Where the global majors built on decades of servo and motion-control heritage, ESTUN did the same in-house ("ALL Made By Estun") and added Germany's Cloos (2020) for premium welding, Trio and M.A.i for the global portfolio. Its 2026 A+H listing (02715.HK) funds the push from China's No.1 toward the global top three.
