Capping machine acceptance test checklist
An acceptance test helps confirm the capper performs against the agreed bottle, cap and output requirement before full production.
Buyer intent
Use acceptance checks to avoid surprises after installation.
For capping machines, acceptance is not only about whether the machine runs. It should also confirm cap start, final torque, visible cap quality, bottle handling, reject rate, changeover and operator usability.
The test should use agreed samples and realistic materials. A capper that runs on ideal samples may still struggle if production bottles, caps or filled weights differ.
Best-fit checks
- Agree samples before the test.
- Measure finished cap torque where relevant.
- Run enough bottles to expose feed or handling issues.
- Check operator access, cleaning and changeover steps.
Specification checks
Acceptance-test checkpoints
These items help make the test practical and measurable.
| Question | Why it matters | What to send |
|---|---|---|
| Sample match | Different caps or bottles can change the result. | Approved production samples and batch details. |
| Output check | The capper must meet the required rate without repeated stops. | Target bottles per minute and test duration. |
| Torque and quality | Caps must be tight without damage or cross-threading. | Torque limits and acceptable finished samples. |
| Handover | Operators need to run and adjust the equipment safely. | Training checklist and key setup notes. |
Decision points
What to document
Faults and remedies
List any stoppages and the agreed corrective action.
Changeovers
Test at least one realistic bottle or cap change where possible.

FAQ
Capping machine questions
What is a capping machine FAT?
A factory acceptance test checks the machine with agreed samples before dispatch or installation.
Should torque be measured?
Where torque is important, measuring finished caps gives a better acceptance standard than visual checks alone.
How long should the test run?
Long enough to expose feed, handling and repeatability issues for the agreed output target.
Can acceptance testing be done on site?
Yes. Site acceptance can confirm the machine works with utilities, layout and neighbouring equipment.
