The effect of punch tip geometry on powder movement during the tableting process.
Axial and radial powder movements during the tableting process have been studied using punches with various tip geometries. Radial powder movement has been shown to occur. Alteration of punch tip geometry did affect both axial and radial powder movement, the extent being dependent on the relative curvature of the punch tip. Addition of lubricant decreased relative axial movement but had little effect on radial movement.
