Deployment status
Company- and series-level evidence is strong; SKU-level evidence is thin, and the two should be read separately. Company level: MIR Databank data put Estun first in China's industrial robot market in 2025 at roughly 10.5% share — the first domestic brand ever to outrank every foreign supplier in that market. In Q2 2026 it shipped more than 10,000 units in a single quarter, a first for a Chinese brand, and has held the top position for six consecutive quarters. FY2025 revenue was RMB 4.888B (+21.93%), of which industrial robots and intelligent manufacturing systems accounted for RMB 3.997B (+31.80%), or 81.8% of the total, at 29.23% gross margin; attributable net profit was RMB 44.97M, back in the black after a RMB 810M loss in 2024. H1 2026 preliminary guidance is RMB 150-180M net profit, though part of that is a non-operating gain from the Nanjing Duanya equity swap. Disclosed customers and installations: batch adoption across the BYD and Seres supply chains; CATL and BYD named as European clients; a BOE Technology partnership with 1,000-plus cleanroom robots deployed; and a flagship automotive-parts line for an unnamed Chinese smart-vehicle brand running 200-plus Estun robots on a single line, payloads 6-500 kg, covering spot welding, adhesive dispensing, SPR self-piercing riveting, FDS, stud welding, handling and arc welding, with 90% automation of core processes, 300,000 part-sets/year capacity, and 60-day commissioning. Capacity and footprint: a Poland plant rated at 15,000 robots/year, 12 global production and application centres, 75 service points, over 95% self-sufficiency in core components, and full ownership of German welding specialist Carl Cloos, acquired for EUR 196M in 2019. Estun completed a Hong Kong listing in March 2026, raising about USD 190.5M. SKU level: the iER20-1760 launched with the iER series on 9 January 2026. Seven months on, no customer case study or deployment report naming this specific model could be found — the deployment evidence in this entry is series- and company-level, and we say so plainly.
When this hits the labor market
0-2 years across Chinese welding, photovoltaic, lithium-battery, metal fabrication and automotive-parts lines, where displacement is already happening rather than approaching. The reason is not that this machine is advanced — a 20 kg, 1.75 m six-axis arm is a specification so mature it is boring — but that the cost lines have crossed. Guosen Securities models a 10,000-tonne-per-year steel structure line at roughly RMB 3.75M/year for manual welding versus RMB 3.30M/year for robot welding: robots are already RMB 450,000/year cheaper, and the gap is widening. One welding robot displaces two to three welders, and every three robots need one general operator at around RMB 100,000/year, against an average welder salary above RMB 180,000. Estun's roughly 25% shipment growth in 2025 and its 10,000-unit quarter in Q2 2026 say this substitution is moving at the pace of shipments, not press releases. 2-5 years for export markets: 15,000 units/year of Polish capacity plus Carl Cloos's German channel push the same cost curve into European metal fabrication and automotive supply chains. One honest counterweight: Chinese manufacturing has a severe labour shortfall of its own — a joint MIIT/MOHRSS/MOE plan projected a gap of roughly 30 million workers in key manufacturing sectors by 2025, a 48% shortfall rate — so a substantial share of this substitution is filling vacancies rather than pushing incumbents out. For an individual welder the difference is narrower than it sounds: not a layoff, but a hard ceiling placed on the bargaining power and wage growth of the trade by a machine that costs RMB 450,000 less per year.

What the machine is
The iER20-1760 is a 20 kg-class six-axis general-purpose industrial arm from Estun’s small-to-medium payload series: 1,756 mm reach, ±0.03 mm repeatability, 273 kg, IP65 wrist and IP54 body, floor or ceiling mounted, paired with the third-generation ERC3-S1 controller cabinet running iER.OS. It does not walk, does not talk, and has no foundation model attached. It is the kind of thing that appears twenty at a time on an automotive body-shop line.
A small naming trap for anyone checking the spec sheet: the model is called “1760” and Estun’s own specification table gives the reach as 1,756 mm. Use the official number.
The choice of SKU needs justifying. Estun launched the iER series on 9 January 2026 and its own “Towards the iER series” page states that the ER line is being upgraded and progressively switched over, with continuity guaranteed only for service, maintenance and spare parts. The older ER20-1780 no longer appears anywhere in Estun’s current Chinese product navigation; its specs are traceable only to third-party hosts, and its repeatability is irreconcilably contradictory between Estun’s own legacy catalogue (±0.06 mm) and third-party listings (0.03 mm). So this entry carries the model that is actually on sale with a complete official spec table.
Two further caveats. The controller designation ERC3-S1 comes from Estun’s cabinet-compatibility list PDF, linked from the product page, which uses the internal code ER20B-1760; we treat that as the match, but it is one inferential step, not a direct manufacturer label. And Estun’s English site, en.estun.com, returned HTTP 502 across every path on 9 August 2026, and even when reachable still shows the superseded ER naming — the canonical link has to be the Chinese page.
Why this should already have been here
This was the plainest hole in the catalogue, and an embarrassing one. MIR Databank data put Estun first in China’s industrial robot market in 2025 at roughly 10.5% share — not first among domestic brands, first overall, ahead of FANUC and ABB. China accounts for 54% of the world’s annual industrial robot installations. Which means the company ranked number one in the largest robot market on earth had no entry at all in a catalogue about who is taking whose job.
The context is bigger than one company. Domestic brands’ share of the Chinese market went from under 29% in 2020 to 55% in 2025. The centre of gravity of the supply side is moving, and where it lands determines how many robots the next decade’s factories can buy, and at what price.
Whose work it takes
Look at that 200-robot automotive-parts line and the process list reads as a job list: spot welding, adhesive dispensing, SPR self-piercing riveting, FDS, stud welding, handling, arc welding. Before automation each of those was a station, a trade, and a shift.
The heaviest concentration is welders. Welder ranked twelfth on China’s official Q4 2022 list of the hundred most labour-short occupations; demand for steel-structure welders is projected to rise from 350,000 in 2025 to 500,000 by 2035, and China Classification Society-certified shipyard welders numbered about 187,800 as of July 2024. Guosen Securities estimates long-run demand for intelligent welding robots in steel structures and shipbuilding alone at 200,000 to 350,000 units. At two to three welders displaced per robot, that is a structural change measured in hundreds of thousands of jobs.
Then the adjacent trades: material handlers and machine tenders, palletisers, grinding and deburring operators, press-brake and stamping operators, die-cast extraction operators. Estun sells a dedicated product line or solution page for each. Grinding and die-casting have a particular character — they are dust and heat jobs that nobody will miss once they are gone, except the people who were doing them, who still need to eat.
Why we care for LostJobs
Because the easiest mistake this catalogue can make is to keep its attention on humanoids doing backflips while the thing actually moving payrolls is a yellow arm that cannot speak and will never trend.
The test is simple: which kind of robot will a person actually encounter at their own workplace? In China the answer is overwhelmingly the arm. The operational stock is around 2 million units, roughly 4.5 times Japan’s, and 2024’s 295,000 installations were 54% of the world total. Estun is number one in that pool.
One methodological warning on robot density, because it will bite anyone who cites it carelessly. The IFR’s November 2024 release, using 2023 data, put China at 470 robots per 10,000 manufacturing employees, third globally. Its April 2026 release, using 2024 data, puts China at 166 per 10,000, twenty-second globally. That is an IFR methodology revision, not a collapse in China’s robot base, and the IFR flags the change in neither release. Cite the 2024 figure of 166 and note the revision, or you will publish a contradiction.
A last point worth stating honestly: the displacement here is not purely zero-sum. Chinese manufacturing has vacancies it cannot fill, and a real share of these robots is filling them. But for a 45-year-old welder, “the trade is short of people” and “my wage will not rise again” can both be true at once — because the party setting the price is no longer the labour market. It is a machine that costs RMB 450,000 a year less than he does.
