FAT Checks for an Electrostatic Powder Coating Line
Define pass or fail checks for booth, recovery, oven and conveyor before signing off a factory acceptance test, and confirm what the supplier will demonstrate and record.
Before signing the factory acceptance test, decide which line elements must demonstrate repeatable function: the automatic powder booth, powder recovery, curing oven and conveyor. A practical approach is to require each element to run as a linked system, not in isolation, and to agree in the request for quotation which observations count as pass or fail.
Ask the supplier to propose measurable checks: does the booth maintain its intended airflow and containment during a run; does recovery return powder without blockage or excessive carryover; does the conveyor move parts through the booth and oven at a consistent speed; and does the oven reach and hold its set condition across the part zone? For the oven, confirm the curing energy option offered, since electric, gas, diesel or coal choices affect the checks and records the supplier should provide. Treat any catalog figures as reference values only and ask for the values that will apply to the supplied model.
Before requesting a quote, confirm with the supplier which checks will be witnessed, what instruments and records will be used, how pass or fail is judged, and what re-test is offered if a check fails.
