PSPF: Strong and soft holds better

When bags made of thin film are filled with liquids, they become wrinkled. In order to ensure safe and fast handling, J. Schmalz GmbH combines two materials with very different properties in its new bellows suction cup PSPF: The sealing lip is particularly soft and adaptable, while the bellows is reinforced. Both components are firmly connected to each other and can thus seal optimally and at the same time follow the dynamics of particularly fast packaging processes. This enables the gripping of liquid, solid or powder-filled pouches and packages with delta robots, in case packers and pick & place applications - even with a low fill level.

The large shaft diameter allows a high flow rate and the 3.5 folds of the bellows easily compensate for height differences. This means a high holding force and thus - in combination with the sealing lip - a secure hold during fast cycles. The new PSPF bellows suction cup is made of FDA-compliant silicone and is suitable for contact with food. It is available in 33, 43 and 53 millimetre diameters.
