Supplier shows the vacuum tool holding one aluminium enclosure panel. Our job starts with stacked panels and ends in an assembly fixture. Separation and support through that move are still unexplained.
Give the supplier representative incoming stacks and the receiving fixture details, then ask for the proposed separation, support and single-panel confirmation through the complete sequence, including how a suspected double is handled.
Then ask them to demonstrate that actual condition through release into the fixture, not infer it from a bare-sheet seal, with the panel support and any manual separation work visible.
