Factory acceptance test (FAT) checklist for packaging machines
Short answer
A factory acceptance test proves the machine meets the agreed specification on your own product and packaging before shipment. Check output speed, dosing accuracy, seal quality, change parts, safety functions, documentation and the spare-parts list — in person or by live video.
Key takeaways
- Send your real product and packaging for the FAT.
- Measure speed and accuracy over a long run, not a few cycles.
- Check every change part and safety stop.
- A recorded video FAT is a valid alternative to travelling.
Before the FAT
- Agree the test criteria in writing: speed, accuracy, reject rate and container sizes.
- Ship enough product, film, pouches, bottles, caps and labels for a meaningful run.
- Ask for the electrical drawings and HMI screens in advance.
During the FAT
- Dry run: the machine cycles without product at full speed.
- Product run: run long enough to see the machine warm up and settle.
- Accuracy: weigh 30+ consecutive packs per nozzle or head.
- Seal integrity: squeeze, drop and water-immersion tests on bags and cups.
- Changeover: change to every size you ordered and time it.
- Safety: test emergency stops, door interlocks and guards.
- Fault handling: no bottle, no fill; no cap; film end; low air pressure alarms.
Remote FAT by video
Every machine we ship is filmed running before packing, and test reports are provided. For a remote FAT, agree the test script in advance, then follow it on a live video call: the engineer shows the HMI settings, the scale readings and close-ups of seals while you watch.
Documents to receive
- Operation and maintenance manual in English
- Electrical and pneumatic diagrams
- Spare and wear parts list with part numbers
- Test report and video
FAQ
Is a video FAT acceptable?
For most standard machines, yes. A live call with an agreed test script and recorded results covers the same checks as an in-person visit.
Who pays for the FAT materials?
Usually the buyer supplies product and packaging materials; the manufacturer supplies labour, power and air. Agree this in the contract.
What happens if the machine fails the FAT?
The manufacturer corrects the issue and repeats the failed tests before shipment.
