A demonstration factory is handed over as an operating line, not as a single machine, so the documentation that accompanies it matters as much as the hardware itself. Before you accept a delivery, ask for the record of the engineering sequence behind the line, the boundary drawings and wiring documentation, the component records for anything bought in, the test evidence with its acceptance conditions, the role list for the people who built it, and the as-built set that lets you change the line later without guessing.
Why a demonstration factory needs a different document set
A stand-alone machine is accepted on one bench, against one duty. A demonstration line is accepted across several duties at once: process steps designed around your parts, equipment built to that design, control work that joins the steps together, and the installation and commissioning that make the whole thing run. Every one of those stages leaves a trace, and a buyer who receives only a machine manual at the end has no way to see how the stages fit. That is the practical difference between a product card for an Industry 4.0 demonstration factory and taking delivery of one as an engineered system: the card names the outcome, the documents carry the reasoning that got there.
There is a second reason. A demonstration line is rarely the last one. It is built to be copied, extended or re-sited when the real production runs are laid out later. Documents that exist only to close a purchase order will not support that second life; documents that record decisions, boundaries and versions will.
The engineering sequence should be visible in the paperwork
PowerDe describes its automation work as one chain run by an integrated team: process analysis, solution design, mechanical structure design, electrical control design, equipment manufacturing, on-site installation and commissioning, and then delivery and acceptance. Ask for one document per link, in that order. For each link you want the input that was taken, the decision that was made, and the person or role accountable for it. A single combined report that jumps from your process to a finished line tells you the answer and hides the working, which is exactly what you will need six months later when a step has to move.
This is where an equipment manufacturing automation services scope is worth pinning down in writing before the work starts. If the same supplier runs the design, the build and the commissioning, the handover should show the handoffs between them rather than smoothing them over: who signed off the process scheme, who released the mechanical design for manufacture, who released the control design for the line.
Boundary drawings and control documentation
In a line, most disputes live at the boundaries: where the new equipment stops and your building, utilities, existing machines and existing conveyor work begin. Ask for drawings that show those interfaces and label what is inside the supply and what is outside it. Then check that the same boundary appears in the electrical package, because a boundary that is drawn mechanically but not drawn electrically becomes an argument about cable, panel space and power at the worst possible moment.
For the control side, ask for the wiring documentation and the panel arrangements that match what is physically installed, not the version issued when the order was placed. Control work changes during commissioning more than any other part of a line project, and a buyer who accepts an out-of-date control package inherits every later fault as an archaeology project.
Records for the parts somebody else made
A demonstration line mixes fabricated work with bought-in components, and the bought-in items are where the traceability problem starts. For each of them ask for the identification as installed, the supplier documentation, and a statement of who is answerable for the item when it fails inside the line. Whether your own team keeps spare stock of a part or buys it through the integrator is a decision you can only make properly once you can see what is in the machine and how it is identified.
This is a request, not an assumption. Nothing on the category page for automated production line solutions states which components are sourced from whom, so the split has to be agreed with the supplier and written into the handover list before delivery rather than reconstructed from a nameplate afterwards.
Test evidence, and the conditions written beside it
A demonstration line is usually proved in front of visitors, which is the least useful way to prove it to yourself. Ask for the test records behind the demonstration: what was tested, on which parts or samples, under what set-up, what passed, what was noted as outstanding, and what has to be true for each item to be signed off as acceptable. A test record without its acceptance conditions is a photograph of a moment; with them it becomes a contract you can hold to when the line is running for real and something behaves differently.
Ask also for the difference between what was tested on a bench or a single station and what was tested as a complete line. Those are two separate claims, and a buyer who conflates them will set production expectations on evidence that never covered the whole route.
Who built it, and who to call afterwards
Integrated engineering work is organised by role rather than by one generalist: mechanical engineering, electrical engineering, automation engineering, testing, manufacturing and project management each appear in PowerDe's description of its engineering team. Ask which role owns each part of the handover package, and ask for that mapping to stay valid after the line is accepted. A document set that was assembled by one project manager who has since moved on is a document set with no author.
As-built versions, change notes and the acceptance signature
Close the handover on three things. First, the as-built set: drawings, wiring and component lists that match the line standing in front of you, marked as as-built rather than as designed. Second, a change record: what moved from the approved design during manufacture and commissioning, why, and who authorised it. Third, the acceptance document itself, written so that each item has a clear outcome and a date, and so that anything still open is listed as open instead of being absorbed into the narrative.
If you are planning a first line with an integrated engineering team services arrangement, agree the document list at the start of the project and treat it as a deliverable in the same sentence as the equipment. A handover list written after commissioning can only describe what somebody happened to keep; one written at the start decides what gets kept.
One honest limit on this checklist. The public pages describe the service chain and the product, not the contents of a handover pack, and they print no schedule, no test protocol and no component list. So treat every item above as a question to put to the supplier and a line to have confirmed in writing, and take the actual figures, standards and sign-off thresholds from your own project documents rather than from any article about the category.
