Optimize Lower Punch Ejection Height For Maximum Press Speed & Increased Product Yield

By Todd Martin, Sr. Technical Service Engineer

Accurately setting the lower punch ejection height in your tablet press is crucial to the ejection process. Positioning the punch too low or too high can damage tablets or cause machine malfunction respectively. The adjustment process varies depending on the press make and model, with most manufacturers advising alignment of the punch tip with the die table at ejection. However, the rotation of die tables can disrupt their level, complicating the setting. Explore how to optimize results by using the shortest lower punch to set ejection height when the die table is at its highest, and rechecking with the longest lower punch at its lowest point.
