KVG with suction cups offers further advantages in circumstances where the surfaces of objects might be wet or oily, said Josef Karbassi, vice president of Piab’s automation division. “The alternative suction cups can better withstand the challenges posed by the presence of water and oil,” he explained.
“Under such conditions, and in general where the flexibility of foam is not needed, the suction cups would be more durable and offer the user a longer life.”
Piab’s Value Line features cups in flat-concave, bellows and long-bellows shapes, and with long thin lips for good sealing on slightly corrugated surfaces, such as corrugated cardboard. Its Duraflex suction cups combine firm bellows with soft, flexible lips made from a specially developed material that features the elasticity of rubber and wear resistance of polyurethane, making them suitable for uneven and porous surfaces.
