    5000 nameplates, that's quite a lot. So is 10000 screws in and out :-(

    Ignoring costs (some homework for you) I'd consider the following:

    1. Make a cover sheet from acrylic, pocket the sheet to take the plates at a about 50% to 75% depth (to allow for easier removal) and have several suction holes with countersinks positioned in the pockets under the work pieces
    2. Get a machine shop to stamp out the blanks to the required size
    3. Load up the pockets with the blanks
    4. Fire up the vacuum
    5. Engrave away

    Around each pocket edge you could also have a dimple hole on a center-line to get a tool to help with plate removal. Hummm, slots rather than pockets might be an idea but harder to align the blanks I guess...

    YMMV :-)

    Hi Nicol - For 5000 make a custom vac jig and use an O-ring (hole thru to a passageway) to hold each piece down. Don't try to pull vac thu a material. Say 200-500 pieces to a board each with an oring. The back of the board has grooves to communicate the vac to the holes and O rings. Then glue a board to the back of that to create passageways vs grooves. I'd do it in aluminium and screw the backboard on and use sealant. But an MDF or melamine board will be a good prototype, this way you can do the lot on one hit. You can also glue a thin soft rubber or foam sheet to the face and drill the holes. Then the first pass will custom cut the gasket. Peter
