TABLET DESC
Tablet presses or Compression machines are mechanical devices that compress granulated powders into uniform tablets for pharmaceuticals and other solid-dosage products . These machines force material between matching upper and lower punches seated in a die cavity to fuse it into a solid form. In operation, the lower punch first lowers into the die to create a cavity; powder is fed into this cavity (usually from a gravity-fed hopper and feed frame); excess powder is scraped off; then the upper punch descends under high pressure (via cams and rollers) to compress the powder into a tablet. After compression, the lower punch rises to eject the finished tablet. Tablet press machines ensure tablets of consistent size, shape, and weight ; for example, one source notes that “to form a tablet, the granulated powder material must be metered into a cavity formed by two punches and a die, and then the punches must be pressed together with great force”. Because they produce fina...
