The working process of the tablet press can be divided into the following steps: 1. The punch position of the down punch (its working position facing upwards) extends from the lower end of the middle mold hole into the middle mold hole to seal the bottom of the middle mold hole; 2. Use a feeder to fill the middle mold hole with medicine; 3. The punch part of the upper punch (its working position facing downwards) falls into the middle mold hole from the upper end of the middle mold hole, and moves downward to compress the powder into tablets; 4. The upper punch lifts out the hole. The downward punching and rising will push the tablets out of the middle die hole to complete a tablet pressing process; 5. The undershoot drops to the original position, ready for the next filling.
