“Food and beverage manufacturers increasingly use vacuum grippers because they know they won’t damage boxes or what’s inside, whereas mechanical fingers or jaws are more likely to when grabbing the box,” explains Joe Reams, president of Coval Vacuum Technology Inc. “McKee Foods Corp., for example, uses our modular MVG series with a 500-vacuum-cup interface to efficiently grab different size boxes of Little Debbie snacks and place them on pallets. And, makers of cosmetics use the same series with up to 2,300 cups to handle large plastic cases of eyeshadow bottles.”
The benefits of vacuum grippers are well-known among manufacturers in other industries, as well. For one Midwest Tier 1 auto supplier, the right vacuum cups enable the company to move sheet metal quicker through a series of transfer presses so more panels and car parts can be formed per shift.
A couple years ago, the company needed to increase press speed to 10 to 11 strokes per minute from 8 to 8.5, but the holding power of the cups they were using was insufficient. To keep up with customer demand, the company began using Duraflex Friction cups from Piab USA Inc. on one press line.
