Ejection Force Punch
Tablet failure often occurs during ejection of the tablet from the die, and die wall friction is a critical parameter to study for reliable production quality. The Ejection Force Measuring Punch (Ejection Punch) is designed for detailed studies of ejection force when making tablets. It is used on the Huxley Bertram Compaction Simulator, or the simple Huxley Bertram Tablet Test Fixture.
Punch Type: B
Force Capacity: 50 kN
Calibration Range: 0-5kN typical
Linearity: +/- 0.5 % FS
Measurement of the force near the punch tip eliminates most inertial forces from the load trace, and gives a clear high frequency response result.
Note the inertia effects when the punch starts to move upwards and when the punch contacts the tablet.
