3. The punch part of the upper punch (its working position is facing downward) falls from the upper end of the middle die hole into the middle die hole, and descends a certain stroke to press the powder into tablets;
4. Punch up and lift out the hole. Push down and lift the tablet out of the die hole to complete the tabletting process;
5. The undershoot is lowered to the original position and ready for the next filling.
