Physics of Tablet Compression XIV. Lateral Die Wall Pressure During and After Compression

Measurements of pressure exerted by various substances on the die wall during and after compression of tablets have shown that the information derived can be related directly to the ease of formation and ejection of these tablets. The side wall pressure has been found to decay at a measurable rate after the normal compressional force is abruptly removed. Similar studies also have been carried out on preformed tablets subjected to repeated compression.
