Factory Acceptance Checks for a Lithium-Ion Battery Electrode Coater
Buyers should agree pass or fail criteria for coating quality, drying across four 3 m sections, and the 0.6 MPa dry, oil-free air supply before signing off a factory acceptance test.
Before signing the factory acceptance test, decide how the coater will prove it handles continuous cathode and anode coating on electrode foil without disputes over what counts as a pass. Agree the sample plan first: which electrode material, foil width, and coating pattern will be run, and how many metres must be produced before inspection begins.
For coating quality, ask the supplier to define measurable acceptance limits for coating thickness variation, edge position, and visual defects, and to state the inspection method and sampling frequency. For drying, since the unit has 12 m of drying length across four 3 m sections, require temperature readings at each section and confirm how section-to-section stability is demonstrated. Ask whether the test runs at production speed or a reduced speed, and how the result maps to your line.
For utilities, confirm the machine runs correctly at a compressed air supply of 0.6 MPa, dry and oil-free, and agree how air quality is verified during the test. Clarify who supplies test material and who owns rejected output.
Before requesting a quote, confirm with the supplier which checks they will accept as pass or fail, what instrumentation and records are included, and how deviations are documented and resolved.
