During the mixing and qualification process new powder is transported to the MQS
from a new powder bin and recycled powder is transported from a multibox.
After the stirring time has elapsed, a sample can be taken from the powder mixture
and checked using suitable methods, e.g. MVR measurement (Melt Volume Rate),
outside the MQS. Via the controller for the MQS it is possible subsequently correct
the mixture ratio based on the measured results, without the need to discharge the
power mixture.
The prepared, refreshed powder is transferred to a multibox (mobile container). For
this purpose a multibox is pushed under the mixing bin and coupled. In the base of
the mixing bin there is a valve for discharging the powder. The level in the multibox
is monitored via a powder sensor in the MQS. The discharge of the powder into the
multibox is controlled via the controller for the MQS.
The multibox with the refreshed powder is pushed to the docking station on the
machine and coupled.
The docking station fills - depending on the filling mode selected - the powder
supply/dosing bin in the machine in the automatic or manual mode. After the end of
