TDP 6s

Process
The basic mechanism of the TDP 6s
®
involves filling the Tooling (Die, Upper Punch, and Lower
Punch) with powder, compressing the powder, and ejecting the tablet.
Filling the Tooling with Powder
The dry materials are poured into the Hopper, which funnels the powder into the Boot. As the
Hand Wheel is manually operated, the Top Cam Drive Shaft withdraws the Upper Punch from the
Die and moves up the Lower Punch to the Die.
When the machine is operated by the motor, the Drive Belt Pulley and V Belts initiate the movement
of the Cam Drive Cog, which moves the Top Cam Drive Shaft to withdraw the Upper Punch from
the Die and pushes up the Lower Punch.
Compressing the Powder
After the powder is filled in the Tooling, the Top Cam Drive Shaft drives the Upper Punch into the
Die, and the Lower Punch is then raised by the Top Cam Drive Shaft. Both punches then move
together to compress the powder under high pressure.
Ejecting the Tablet
After both punches compress the powder into a tablet, the Top Cam Drive Shaft withdraws the
Upper Punch while the Lower Punch is pushed upward to expel the tablet. The tablet is then
pushed out of the way by the Boot to prepare for the next tablet compression.
