RTP 41 ® Process
The basic mechanism of the RTP 41 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 Hoppers and funneled into the Fill Trays. As the machine
operates, the Turret moves, which causes the Upper Punches to withdraw from the Dies. During
this process, powder makes its way from the Fill Trays into the moving Turret and the Die bores.
Compressing the Powder
After the Die bore is filled with powder, the Upper Punch is driven into the Die. 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After both punches compress the powder into a tablet, the Upper Tooling is withdrawn and the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 Trays' Take-Off Blade to prepare for the next
tablet compression.
