Where Does The Vibration Go When I Mount My Press On Isolators?

1.	Where Does The Vibration Go When I Mount My Press On Isolators?
Answer» Internal forces caused by the stamping operation occur whether the press is bolted to a foundation or installed on isolators. HOWEVER, the magnitude of the vibration within the press is lower when using vibration isolators. It is a common misconception that BOLTING a press to a foundation somehow “sucks” the vibration out. Bolting a press to a foundation actually SUBJECTS it to more vibration and impact force. Vibration isolators are cushions that transform a sudden shock pulse into a decaying SERIES of longer duration forces. Imagine hitting a brick wall with your fist. It would hurt! Now imagine hitting the wall with the same energy, but with your hand in a well padded boxing glove. It hurt less! Why? It’s because the impact duration is longer, effectively reducing the impact force. Short duration impacts mean higher force. This is the same thing that happens on a hard-mounted press. The sudden release of potential energy at snap-through causes the press foot to slam against the foundation. This fast duration, high magnitude force hits the foundation and the foundation responds in kind, sending damaging forces BACK into the press.
