FIPA presents: Oval vacuum cups

Introducing the newly developed oval vacuum cups series.

The vacuum cups are characterised by a very long cycle life, which has also been successfully demonstrated against vacuum cups of competitors in practical operation. The long service life is enabled by means of a new high wear- and oil-resistant NBR material and a special vacuum suction cup construction which minimises the load on the vacuum cup during handling.

FIPA presents: New ID grippers for parts with different diameters

Flexible and service friendly

The pneumatically operated, single-acting ID grippers from FIPA GmbH have already established themselves as the alternative for workpieces with holes or cut-outs or for when vacuum cups or grippers aren’t just right for handling goods. FIPA has completely overhauled its portfolio and now offers users maximum flexibility with minimal set-up time.

The small ID grippers are now equipped with food-safe gripper heads made of polyamide (PA) and are suitable for light and small parts with openings measuring 3 to 10 millimeters in size. If necessary, the gripper heads can be easily exchanged in a non-destructive manner.
