Estun Automation (埃斯顿)
Company Overview
Estun Automation was founded in Nanjing in 1993 by Wu Bo, originally working on CNC systems for metal forming machine tools, and moved into industrial robots in the early 2010s. The company is listed on the Shenzhen Stock Exchange under code 002747, with the listing dating to 2015. Headquarters and core manufacturing remain in Nanjing, Jiangsu, with additional domestic subsidiaries in Hubei, Guangdong and Shanghai, and overseas operations that include European and other international entities.
The reason Estun comes up in sourcing conversations is vertical integration. It describes itself as the earliest company in China to independently research and design AC servo systems, and it builds servo drives, servo motors, motion controllers and the robot arm itself. For a buyer that matters because the servo and controller are normally where a low-cost robot programme quietly turns into an integration project. When the robot maker also makes the drive, spare parts and firmware support are one conversation instead of three.
Its product structure is usually presented in three blocks: automation core components and motion control (AC servo systems, inverters, PLC, HMI, vision, CNC), industrial robots and intelligent manufacturing systems, and digital products and services covering equipment data collection, edge computing and production monitoring over a unified OPC-UA interface.
Main Products
- Industrial robots: six-axis series covering roughly 3 kg to 600 kg payload, SCARA, collaborative models, plus welding, palletising and machine-tending workstations.
- Motion control: full AC servo systems (drives and motors), motion controllers, PLC and HMI, machine vision.
- CNC systems for metal forming and machine tool applications.
- Robot integration units built around the Trio motion control platform.
- Digital manufacturing software: design tools, project management transparency system, and the E-noesis industrial digital platform.
Typical end markets named by the company include lithium battery, photovoltaics, 3C electronics, automotive, welding, metal processing, packaging and printing, semiconductor equipment, woodworking machinery, construction machinery and general machine tools.
Key Facts
- Founded: 1993, Nanjing, Jiangsu
- Listing: Shenzhen Stock Exchange, code 002747 (listed 2015)
- Core position: one of the few Chinese suppliers producing both industrial robots and the underlying servo and motion control components
- Robot payload range: approximately 3 kg to 600 kg across the six-axis range
- R&D intensity: the company states research spending of roughly 10 percent of annual revenue
- Service scope: full robot cells and workstations, not only arms
- Note: product specifications, payload/duty ratings and current model lists change frequently; confirm against the official site and the current datasheet for the exact model before designing a cell around it.
Why a Buyer Would Look Here
For a European or North American buyer, Estun is usually evaluated in one of two roles. Either as a direct robot supplier for welding, palletising or machine tending where the cell is simple and the payload is under 50 kg, or as the reference point against which a quote from a Japanese or European brand is judged. In the second role the comparison is genuinely useful, because Estun can quote a complete package including controller and drives, so the price gap is measured on a like-for-like cell rather than an arm alone.
The things to verify during evaluation are the same as with any Chinese robot supplier: whether the local integrator has genuine application experience in your process, whether spare parts are stocked in your region, and what the software and firmware support commitment looks like after the warranty. Those three questions decide more outcomes than the payload specification.
