Tablet thickness and compaction control
The dosage of the drug is determined according to the prescription and pharmacopoeia and cannot be changed. For the time limit of storage, preservation and disintegration, the pressure of a certain dose is also required during tableting, which will also affect the actual thickness and appearance of the tablet. Pressure regulation during tableting is essential. This is achieved by adjusting the downward amount of the punch in the die hole. Some tablet presses not only have the upward and downward movements of the upper and lower punches during the tableting process, but also have the upward movements of the lower punches, and the relative movement of the upper and lower punches completes the tableting process. However, the pressure regulation is mostly realized by the mechanism of adjusting the upward and downward flow to realize the pressure regulation and control.
