Search for "Industry 4.0 demonstration factory" and you will find supplier after supplier claiming the label. Before the quotation stage begins, the first job for a procurement team is to separate a genuine demonstration line from a showroom corner with a conveyor and a screen. The concept originated in the German Industry 4.0 initiative: a factory in which machines, products and logistics systems communicate with each other through a common digital thread, so that production can be monitored, scheduled and adjusted from the same data model that designed the product. A demonstration factory, in that sense, is a real line built to prove the concept end to end — not a slide deck.
If you are evaluating a supplier's Industry 4.0 demonstration factory, the questions below are worth putting on the agenda of your first site visit or video walkthrough.
1. What is the demo line actually proving?
Ask what decision the demonstration exists to support. A useful demo line mirrors the process you buy: if you need automated assembly fixtures, online dimensional inspection or robotic loading, the line should run those operations with your class of part, not display generic robots. Ask to see the same equipment type you would receive — an automated workstation, a test station, a handling cell — operating under normal cycle conditions. Shenzhen PowerDe Automation Precision Equipment describes its engineering work as spanning process analysis, scheme design, mechanical structure, electrical control, equipment manufacturing, installation and commissioning through to delivery acceptance, so the natural question is which of those steps you can watch functioning in the demo, and which remain drawings.
2. Who built the equipment, and who maintains it?
Many "solution providers" integrate machines from third parties and never touch the mechanics. Ask directly which stations in the demo the supplier designed, machined, wired and programmed in-house, and who services them. The distinction matters at contract time: an integrator that owns mechanical design, PLC and HMI programming, sensor integration and on-site commissioning can respond to a fault without routing it to a subcontractor. Ask what deliverables come with the project — a supplier that hands over equipment layout, 2D and 3D design files, electrical schematics, PLC and HMI programs, fixture drawings, a BOM, operation instructions, test reports and factory acceptance criteria is giving you assets you can maintain; a supplier that hands over a sealed machine and a manual is not.
3. Does the data flow prove anything?
Industry 4.0 is a data argument, so insist on a data walkthrough rather than a tour. Request a live demonstration of a job being released from a system, tracked through the line, and closed out with recorded results: cycle counts, test outcomes, alarm histories and downtime reasons. Ask where those records are stored, whether your own engineers can pull them, and whether traceability follows a single part number. Ask what happens when a station goes down — does the control system flag the deviation and stop the flow, or does the line keep running and reconcile afterwards? If the supplier shows you a dashboard but cannot show you the underlying records and how they were produced, treat the dashboard as decoration.
4. Can they run a feasibility triage honestly?
A credible automation partner will tell you which of your processes should not be automated yet. A serious feasibility review separates the steps suited to full automation, the steps that belong in semi-automatic workstations, and the steps that should stay manual for now. Watch for that honesty during the demo conversation. Ask for a written feasibility assessment that names the automation candidates, the exclusions and the reasoning, including rhythm and takt planning and the personnel configuration assumed in the numbers. Vendors who promise to automate everything are selling a picture, not a plan.
5. How does the line get accepted and handed over?
Ask what "finished" means. Expect a defined sequence: functional testing, cycle-time testing, stability and safety testing, abnormal-condition testing, factory acceptance, on-site installation, operator training and documented acceptance criteria. Ask what tests are run before shipment, who signs them off and what you can refuse. Ask whether on-site installation, commissioning and training are quoted as part of the project or billed later as extras, and what after-sales support looks like once your own operators are running the line without the vendor's engineers in the room.
6. What does this supplier already industrialize at scale?
A demonstration factory is most convincing when the same organization ships production equipment in volume. Ask which product families the supplier manufactures repeatedly — for PowerDe that includes process and display-bonding equipment, coating and production-line equipment, and non-standard automation equipment built to a customer's product and process, alongside cleaning equipment that a factory also has to keep running. A buyer can use this breadth as a check: suppliers that build machines for their own production lines, and that have to keep cleaning and inspection stations working inside those lines, are used to equipment that must survive shifts rather than a single demo day.
7. Which claims on the website can you verify today?
Put every number you are given into writing before you rely on it. Patent counts, project counts and staffing ratios are the sort of figures that drift between pages of a single site, so ask which specific patents, projects and personnel structure support the claim, and compare it against what you see at the factory. Ask for the customer references the demonstration line came from and, where confidentiality allows, for a reference call. A supplier comfortable with that kind of verification is usually the one whose demonstration line is a working production asset rather than a marketing set.
A short evaluation checklist
- The demo runs your operation, not a generic one, with your class of part.
- In-house design, wiring and programming are identifiable station by station.
- Data is demonstrated live: job release, tracking, recorded results, alarms, downtime.
- Feasibility triage names processes that should not be automated yet.
- Acceptance criteria, test records, drawings and programs are contractual deliverables.
- Installation, training and after-sales support are quoted, not promised verbally.
If your evaluation starts from a real production problem — low labour efficiency, unstable manual quality, detection that depends on an operator's judgement, or an existing line that needs loading, unloading and inspection added — send the process description rather than a request for a catalogue. That is what lets an engineering team tell you which part of your line is worth automating first.
