Tablet press generally known as tableting machine, pharmaceutical tablet press, tablet compressing machine, or tablet punching machine is often a mechanical device that compresses powders into tablets of uniform size, shape, and weight containing approximately the identical volume of Active Pharmaceutical Ingredient (API) and excipients. Besides its use within the pharmaceutical industries for manufacturing types of tablets, it is also used to manufacture illicit drugs, cleaning products, and cosmetics.
All tablet press employs exactly the same concept of compression. The basic unit of the tablet press is tooling composed of two punches along with a die called a station. The upper and lower punches come together within the die that contains named formulation.
The development of tablet press has become a continuous process. During the past, we have hand-driven tablet press which has been modernized to electrical driven tablet press.
Cause of continuous development of tablet press:
Progression of newer technology in tablet production e.g. development of direct compression technology.
Growth and development of stringent standard of cleanliness to conform using the Current Good Manufacturing Process (CGMP).
The introduction of automation and continuous monitory of production processes.
Increased rate of production as a result of increased demand, multiplication of disease conditions, and exponential increase in population.
Types/Classification of Tablet Press
Tablet press in current use could be classified into:
Single punch/single station/eccentric presses.
Multi-station/rotary presses.
There are many types of presses, created by many companies, ranging in space, speed, and capacity.
