Introduction to the main structure and usage of the tablet press

The tablet press machine is mainly used for the tablet process research in the pharmaceutical industry. It is an automatic continuous production equipment for pressing granules into round, special-shaped and tablets with text, symbols and graphics with a diameter of no more than 13mm. The punches and dies of the tablet press are under a lot of pressure during the tablet pressing process. They are usually made of bearing steel and heat-treated to increase their hardness. There are many types of punches, and the shape of the punch depends on the desired shape of the tablet. According to the shape of the die structure, it can be divided into circular and special-shaped; the shape of the punch section is flat, hypotenuse, shallow concave, deep concave and comprehensive. Plane and hypotenuse punches are used for pressing flat cylindrical tablets, shallow concave punches are used for pressing biconvex tablets, deep concave punches are mainly used for pressing the core of coated tablets, and composite punches are mainly used for pressing Shaped sheet. In order to facilitate the identification and taking of medicines, the name of the medicine, dosage and vertical and horizontal lines can also be engraved on the end face of the die. To compress tablets of different doses, dies of suitable size should be selected.
