ER3-400
Estun AutomationThe ER3-400 is a SCARA industrial robot manufactured by ESTUN Automation Co., Ltd., featuring a 400mm reach, 3kg payload, 4 axes, and IP20 protection rating. It is part of ESTUN's broader SR-series SCARA lineup that includes 500mm and 600mm reach variants with up to 6kg payload. ESTUN is a Chinese industrial robotics company listed on HKEX, with manufacturing presence in Nanjing and a South China base in Foshan, Guangdong. Pricing for the ER3-400 itself is not specified in the available sources; the dollar figures extracted appear to relate to an unrelated ER/Studio software product. Autonomy level is that of a standard industrial robot arm — it executes programmed tasks autonomously once deployed, with no human performing the task itself.

Evidence-graded claims from the Estun Automation deep report
Estun is the #1 domestic industrial robot shipmaker in China for 8 consecutive years, and in H1 2025 became the first domestic brand to surpass foreign brands in shipments.
Multiple Futunn financial news reports [12][9] assert this milestone, but these are financial media relaying company disclosures — no independent third-party market audit (e.g., IFR, GGII, or MIR) is cited in the dossier to corroborate the specific H1 2025 surpassing claim.
from Estun Automation deep report →Estun's industrial robots operate autonomously on manufacturing tasks (welding, assembly, material handling) without human teleoperation during task execution.
The most detailed autonomous-operation evidence in the dossier (5h10min continuous run, 99.4% QC pass rate, 108 motors) comes from a Neuromeka-authored paper [18], not from Estun's own documentation, leaving Estun's specific autonomy level independently unverified.
from Estun Automation deep report →Estun's use of Siemens Tecnomatix Process Simulate X reduced virtual commissioning time by 30% and overall costs by 20%.
The figures come exclusively from a Siemens-published case study [3], which is a vendor/commerce source with a commercial interest in promoting the outcome; no independent customer audit or third-party verification is present in the dossier.
from Estun Automation deep report →Estun has a global footprint spanning 64 countries and regions, with 75 service centers and 7 manufacturing bases, including a completed factory in Poland.
The Siemens case study [3], Futunn IPO news [9][11], and Minichart annual report [8] all cite these figures, but all sources either originate from or closely relay Estun's own disclosures; no independent on-the-ground verification of the Poland factory's operational status or the full service-center count is present.
from Estun Automation deep report →Estun's FY2025 revenue reached RMB 4.888 billion (+21.93% YoY), with a return to profitability (net profit RMB 41.34 million) after a ~RMB 811 million net loss in FY2024.
Figures are reported by Futunn financial news [12] and Minichart [8] based on Estun's annual report disclosure; as a listed company (A+H), these are subject to regulatory audit, but the dossier contains no independent analyst or auditor confirmation beyond the company's own filings.

Estun achieves >95% in-house production rate for core robot components (controller, servo system, body design).
The >95% figure is a vendor-only claim from Estun's official website with no independent audit, supply-chain analysis, or third-party confirmation found anywhere in the dossier [conflict noted explicitly in dossier].
from Estun Automation deep report →Estun aims to capture up to 10% of the European industrial robot market through a competitive pricing strategy and integrator network.
The 10% target is a forward-looking aspiration reported from a Hannover Messe trade-show article [5]; no evidence of current European market share level or progress toward this target is found in the dossier, and the dossier explicitly flags this as an unverified ambition.
