Battery Manufacturing EquipmentCell airtightness detection machine
Shuangren's cell airtightness detection machine sits in its prismatic power and storage cell finishing range, next to helium charging, plug handling and ball sealing. The listing gives no model, test pressure, leak limit or cycle time, so a quote should start with the test method and the cell's sealing state.
By SHUANGREN
What the listing gives and what to ask for
Shuangren lists an airtightness detection machine in its cell finishing range. The listing has no fixed model, test pressure, leak limit, sensitivity or cycle time. Shuangren sells helium charging stations as separate items, so ask whether this tester uses helium mass spectrometry or another sensing method.
Ask the supplier for the sensing method and the state of the cell at test. A temporary closure, a final seal and a gas-filled cell are three different conditions. Request the fixture, the test sequence, the reference-leak or reference-part method and the units used for acceptance, and only then talk about a leak-rate figure.
| Parameter | Published value | Record status |
|---|---|---|
| Equipment type | Airtightness detection machine | known |
| Catalogue position | Prismatic/power and energy-storage cell equipment series | known |
| Related operations | Helium charging, sealing, restraint handling and wrapping listed in the catalogue | known |
Catalogue values apply to the configuration and test method the maker states. Ask for the values that apply to your configuration.

Make sealing and testing duties explicit
Send cell drawings, the sealing state, the test gas you allow and the defect criterion you need. Ask which upstream station prepares the cell and how the tester rejects or passes it. If helium charging and plug insertion are in the scope, show on the process map how they connect to the detection step.
The trial should include repeat tests on known reference parts and a plan for dealing with fixture leaks. Settle changeover, calibration and the result saved against each cell ID. The category name tells you what kind of machine it is; the trial tells you whether it suits your cell.

Write the leak-test method into the quote
Before choosing a threshold, ask the supplier to state the measuring principle, test medium, part preparation, fixture and ambient conditions. The approved procedure should describe the pressure sequence and the stabilisation and measurement periods. Because helium appears elsewhere in the range, ask for the detector type and sensitivity of this tester in particular. Your cell engineering team should approve the test conditions the cell can safely take.
Agree reference artefacts and challenge samples, approved by the supplier, for the repeatability and rejection demonstrations. Log the fixture ID, reference status and settings with each result. Ask how the machine tells temperature drift, fixture leakage and a poor seal apart from a faulty cell. Collect calibration and maintenance documents for the chosen method. Choose gas, pressure and any destructive checks together with Shuangren for your specific cell.

Judge borderline parts and retests under one written method
Get the sensing principle, test units, pressure conditions and stabilisation sequence in writing. A leak-limit number means little until those conditions and the cell's state are known. Agree suitable reference parts or reference leaks with the supplier and your quality team before any demonstration.
Look at repeat measurements, a known failing condition and an interrupted run, all under that same method. Ask how the machine separates fixture leakage from the cell result and how retests are logged. Ask Shuangren to state the method, sensitivity and cycle time for this machine in the quotation.
The Hangke helium leak-check station shows how a helium method is specified, which is useful for comparison when the test method of this machine is confirmed.

Questions that change the purchase
| Decision | What the catalogue says | Next step |
|---|---|---|
| Which leak-test method is proposed? | The listing names the machine with no method, pressure or threshold. | Request the medium, pressure sequence, detection principle and calibrated reference. |
| How will repeatability be accepted? | The listing gives no fixture or test-condition details. | Agree reference leaks or artefacts, challenge tests and recorded limits. |
Equipment questions
Does the tester use helium detection?
The catalogue lists helium charging and airtightness detection as two separate stations. Ask Shuangren which detection method this machine uses.

- The test pressure, the units used for leak rate and the minimum detectable leak on your cell.
- How fixture leakage is separated from a cell leak, and the reference-leak calibration.
