FAT Checks for an Automatic Conveyor Sandblasting Machine
Buyers should define measurable pass or fail checks for conveyor speed, gun operation, and chamber access before signing off an automatic conveyor sandblasting machine at the factory acceptance test.
Before signing off an automatic conveyor sandblasting machine, decide how the factory acceptance test will prove that the conveyor and the blasting guns work together as a controllable system, not just that the machine runs. A practical approach is to require a timed test piece run at more than one conveyor setting and to record the results against agreed criteria.
Ask the supplier to demonstrate the adjustable conveyor speed across its range, with the catalog reference of 0–5 m/min treated as a reference value rather than a guarantee for the supplied unit. Confirm how speed is set and verified, and whether the test will use marked test pieces to show repeatability. For the 12 blasting guns, define a check that each gun operates and can be adjusted, and ask how the supplier will show this without relying on visual impression alone. Confirm that test pieces fit the working chamber reference of 1,400 × 1,100 × 1,000 mm and that loading and unloading through the conveyor path is included in the test.
Before requesting a quote, confirm with the supplier which pass or fail criteria they will accept in the FAT, how measurements are recorded, who witnesses the test, and what documentation is provided.
