RTP 9® Process
The basic mechanism of the RTP 9® involves filling the Tooling (Dies, Upper Punches, and Lower
Punches) with powder, compressing the powder, and ejecting the tablets.
Filling the Tooling with Powder
The dry materials are poured into the Hopper, which funnels the powder into the Fill Tray. As the
machine operates, the Turret moves, which causes the Upper Punches to withdraw from the Dies.
During this process, powder is moved by the Turret and is guided into the Die Bores by the Fill
Tray.
Compressing the Powder
After the Die Bore is filled with powder, the Upper Punches are driven into the Dies. The Upper
and Lower Punches then compress the powder under high pressure.
Ejecting the Tablet
After both punches compress the powder into a tablet, the Upper Tooling is withdrawn and the
tablet is then pushed out of the Die Bore by the Lower Punch. Once the tablet has been ejected
out of the Die Bore, it is slid out of the way by the Fill Tray's Take-Off Blade to prepare for the next
tablet compression.
