Leaving an Appropriate Amount of Fixture Material in the Molding Pool and Transferring the Remainder to the Supply Pool

Leave a layer approximately 10 mm (0.39 in.) thick of fixture material in the molding pool and transfer the rest of this material to the supply pool.

When placing a mesh rack, or something similar, on the bottom to enable the job to be removed from the pool after output and without having to touch the job directly with your hands, leave a layer of fixture material that is deep enough to hide this rack.

MEMO If the first few layers of the fixture are slightly shifted toward the reuse pool, increasing the depth of the fixture material first stored in the molding pool by about 10 mm may improve the situation.
Procedure
  1. Raise the molding pool table to a position where it is easy to ladle out the fixture material.
    Exercise caution to prevent the fixture material from overflowing from the pool due to the table being raised too high.

  2. Place the inlet of the dust collector close to the supply pool, and then switch on the dust collector.
    If the dust collector was left behind during the previous work, this step is unnecessary. Proceed to the next step.
    IMPORTANT

    The dust collector is used to collect most of the fixture material that erroneously becomes airborne during work, preventing this material from spreading throughout the room.

    So that the fixture material in the supply pool is not suctioned by the dust collector, pay attention to the position of the inlet and to the suction power.

  3. Use a scoop to transfer the fixture material from the molding pool to the supply pool.
    To prevent the powder from becoming airborne, do not drop the fixture material from a high position or suddenly tilt the scoop. Slowly tilt the scoop close to the fixture material in the supply pool.

    If it looks like the fixture material may overflow from the supply pool, lower the supply pool table.

    IMPORTANT

    If you find clumps of fixture material during this work, remove them with a scoop or a similar tool, and then pass these scoops through a sieve. Alternatively, pass all fixture material being transferred to another pool through a sieve finer than 100 mesh (mesh opening: 118 µm).

  4. Repeat steps 1 and 3 to transfer the fixture material from the molding pool to the supply pool, leaving a layer approximately 10 mm (0.39 in.) thick in the molding pool.
    When placing a mesh rack, or something similar, on the bottom, leave a layer of fixture material that is deep enough to hide this rack.
  5. Roughly level the fixture material left in the molding pool, eliminating any major unevenness from the surface.
    It is recommended to use a squeegee or a similar tool to level the surface by gently stroking it.
  6. Raise the table until the leveled fixture material surface approaches the top edge of the molding pool.
    If the layer of fixture material left behind is less than 10 mm (0.39 in.) thick or if the rack placed under the job cannot be hidden, adjust the amount of fixture material by, for example, moving some fixture material back from the supply pool.
  7. Switch off the dust collector and move it away from the machine.
    If you will continue by adjusting the depth of the fixture material in the supply pool, do not move the dust collector away from the machine.
