Press-line die drop: which shock absorber?

A 50 kg die drops 150 mm. What stops it safely? Watch the 36-second explainer, check the calculation, then open the same example in ImpactCal and change it to your own machine.

Inputs (SI units)

Mass m	50 kg
Drop H	0.15 m
Cycles C	300 /h

Calculation

Impact velocityv = √(2·g·H) = √(2·9.81·0.15)	1.72 m/s
Kinetic energyE1 = m·g·H = 50·9.81·0.15	73.6 J
Drive energyE2 = m·g·s = 50·9.81·0.025	12.3 J
Energy per cycleE3 = E1 + E2	85.8 J
Energy per hourE4 = E3·C = 85.8·300	25 750 J/h
Effective massme = 2·E3 / v²	58.3 kg
