Low Vacuum High flow

By Daniel Pascoe Most vacuum pick-and-place applications require a moderate vacuum level of about 20+”Hg. For example, a 40-mm diameter cup has a theoretical lifting force at this vacuum level of about 17 lbs. This is of course affected by numerous conditions such as inertia and surface type. There are many options the user may […]
