The development process of tablet press
A machine that places granules or powdered materials in a die hole and presses them into tablets with a punch is called a tablet press. The earliest tablet press machine is composed of a pair of dies, the punch moves up and down to press the granular material into flakes, this machine is called a single-punch tablet press machine, and later developed into an electric flower basket tablet press machine. The working principle of these two tablet presses is still one-way tablet pressing based on manual compression molding, that is, the lower punch is fixed during tablet compression, and only the upper punch moves to pressurize. This method of tablet compression causes uneven density inside the tablet due to inconsistent upper and lower forces.
