30-minute site visit · no deck, no proposal

An engineer will reach out within two business days using the contact method you chose. For urgent matters, add us on WeChat or call directly — mention 'line inquiry' for priority handling.

Three steps: (1) 30-minute on-site survey — we look at line tact, defect types, and PLC interfaces; (2) we produce a free technical feasibility report; (3) after agreeing on POC scope, KPIs, and refund terms, we sign and deliver within 6 weeks. No slide decks — we talk about your actual line.

FactoryOS runs inside the plant's OT network. Data physically never leaves. IT and OT are isolated via a one-way diode — only configuration updates can enter. Production images and batch records stay on the local server. Data ownership, model weights, and source-code escrow are all written into the contract.

A three-stage cascade: vision detection → vision-LLM review → decision brain. High-confidence samples take the millisecond fast path; low-confidence ones get LLM backstop; everything passes a hard GMP rule gate. On the lighthouse line, miss rate moved from ~1.2% to 0.04% (~30× reduction); your own POC numbers will govern.

FactoryOS satisfies both Electronic Records and Electronic Signatures in one pass: SHA-256 signatures on every decision, full Audit Trail timestamps, written rationale, and original-image evidence. It also aligns with NMPA GMP Annex and EU GMP Annex 11 chapters on computerized system validation, data integrity, and change control.

Yes. FactoryOS ships Kylin V10 SP3 ARM64 images out of the box, with one-flag switching to Huawei Ascend 910B/310B inference, Dameng/OceanBase database adaptation, and one-way diode friendliness. Standard and domestic-stack editions ship side by side; MLPS Level 3 documentation is included.

Traditional vendors hand over a recognition model and leave the workflow to you. FactoryOS delivers an end-to-end decision loop — see (vision), judge (decision brain), and record (electronic batch record) fused at the algorithmic level. Every call carries a written rationale, auto-writes audit records, passes GMP hard rules, and supports human-in-the-loop pause/resume.

The POC contract locks two KPIs: full refund if miss rate misses 0.5%; full refund if false-reject rate misses 2%. Acceptance is measured on your own line data and signed off by both QA teams. If KPIs are missed, Xinlin Tech refunds the full POC fee per the contract — no conditions.
