<p>The present invention relates to a method and system for forming a miniature tablet (12) using a predetermined compression force in a rotary tablet press (10). The predetermined compression force can be in the range of about 50 to about 2,000 Newtons, preferably less than about 500 Newtons. In one embodiment, the predetermined compression force is applied using an adjustable ramp (86) for moving a lower punch (28) upwardly towards a downwardly moving upper punch (68). The height of the adjustable ramp (86) is accurately controlled to precisely provide the predetermined compression force for forming the miniature tablet (12). It has also been found that breakage of punch stems (38, 80) formed on the lower punch can be reduced by providing a reinforced portion of the punch stem (38) formed on the lower punch (28) can be reduced by providing a reinforced portion of the punch stem below the slender portion (36) of the punch stem (38) which enters a bore (44) of the die (40) wherein the miniature tablet (12) is formed.</p> |
