Every manufacturing plant operates on a unique schedule, timed down to the minute or even to the second. If you reduce your pump-down times by several seconds, you may have to rework some of your routines. But, as mentioned before, efficiency is key to competing.
A factory in Portland puts coatings on plastic parts for various applications. They needed to replace some of their vacuum pumps because their older equipment had been phased out. A Leybold representative showed them how they could get increased production by upgrading their pumps. Better pumps would reduce their pump-down time substantially. Initially, they were concerned that their workers' schedules would be thrown off and that they wouldn't be able to make use of the faster pump-down times. But, since they needed to replace their pumps anyway, they decided to give it a try.
Within a few months, the increased efficiency meant they were able to hire another worker to operate the machinery faster. The more efficient pumps paid for that additional worker several times over.
