WebJul 1, 2015 · Using a compaction simulator, it has been shown that tablet ejection force increases with increasing tableting speed during compression of powders lubricated with 1% magnesium stearate. Faster tableting speed corresponds to higher coefficient of friction, μ , but does not affect residual radial die wall (RDW) stress. WebThe advantages of high-precision dosing, manufacturing efficiency , and patient compliance make tablets the most popular dosage forms. Compaction, an essential manufacturing step in the manufacture of tablets, includes compression (i.e., volume reduction and particle rearrangement), and consolidation (i.e., interparticulate bond formation).
