Custom made rubber suction cups and flat vacuum cups

Flat vacuum cups are a custom rubber option for gripping surfaces where the available contact region suits a relatively flat cup profile. The size should fit within that usable area, leaving the lip clear of edges, seams or raised details. Consider the actual surface rather than selecting by the overall size of the workpiece.

Check how the cup approaches the part. A slight angle between the equipment and workpiece can leave one side contacting first, while excessive travel may distort the lip. Evaluate the contact at the intended pickup height and through the complete handling movement with the chosen vacuum system.

Material selection should account for the surface finish and any process residues. Keep the lip clean and avoid using it to wipe across debris before pickup. During inspection, look for localized wear that suggests an alignment issue or repeated contact with a surface feature. A replacement should match both the footprint and installed height, so the machine does not need to compress a different profile simply to reach the original pickup position.

Material options

Rubber compound options, customized alongside the profile and contact conditions.

Hardness selection

Solid rubber options: 30–90 Shore A. Evaluate the contact at the intended pickup height and through the complete handling movement with the chosen vacuum system.
