FAT Checks for a Z-Fold Battery Cell Stacking Machine
Buyers should define measurable pass or fail checks for a two-station Z-fold stacking machine handling electrode sheets, covering stack thickness, alignment, and repeatability before signing off at the factory.
A buyer specifying a two-station Z-fold stacking machine should decide up front which measurements will decide pass or fail at the factory acceptance test, rather than accepting a visual demonstration. Because the equipment handles electrode sheets and produces stacks of 10–30 mm thickness, the test plan should tie each check to those materials and that range.
Ask the supplier to propose acceptance criteria for stack thickness across the stated 10–30 mm range, including how many samples and which positions are measured. For alignment, agree on a measurable tolerance for electrode sheet placement and how it is verified. For the two stacking stations, confirm whether each station is tested independently and whether results are recorded per station. Ask how repeatability is shown, for example by running a defined number of consecutive stacks and comparing results.
In the request for quotation, request the proposed test method, sample size, and recording format. In a demonstration, watch whether the checks are performed the same way each time.
Before requesting a quote, confirm with the supplier which pass or fail criteria they can support with documented measurements, what reference specifications apply to the offered model, and how test results will be recorded and shared.
