tablet press

A tablet press is a mechanical device that compresses powder into tablets of uniform size and weight. A press can be used to manufacture tablets of a wide

variety of materials, including pharmaceuticals, illicit drugs such as MDMA, cleaning products, and cosmetics. To form a tablet, the granulated 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 to fuse the material together.

A tablet is formed by the combined pressing action of two punches and a die. In the first step of a typical operation, the bottom punch is lowered in the die

creating a cavity into which the granulated feedstock is fed. The exact depth of the lower punch can be precisely controlled to meter the amount of powder

that fills the cavity. The excess is scraped from the top of the die, and the lower punch is drawn down and temporarily covered to prevent spillage. Then, the

upper punch is brought down into contact with the powder as the cover is removed. The force of compression is delivered by high pressure compression rolls

which fuse the granulated material together into a hard tablet. After compression, the lower punch is raised to eject the tablet.
