The Vacuum System and its Components
PA01019111_inh_EN.pdf The following shapes are generally distinguished: • Flat suction cups PA01019111_inh_EN.pdf

• Bellows suction cups

Each suction cup shape offers advantages that are reinforced and optimized by the combination with a suitable material. The available Schmalz - The Company
suction cup materials are described in detail in the section “Suction Cup Materials”.

Flat Suction Cups Knowledge
Flat suction cups are particularly suited for handling workpieces with flatly or slightly curved surfaces. Flat suction cups can be evacuated Vacuum
quickly due to their flat shape and low inner volume, therefore they can grip the workpiece in a very short time and can withstand the
forces which result from fast movement of the object during handling.
Advantages of flat suction cups Vacuum Suction Cups
• Large variety of different suction cup materials and shapes
(round, oval, steep or flat leveling sealing lip)
• Flat shape and low inner volume result in minimum evacuation
times
• Good stability of the suction cup allows high shear forces and Special Grippers
positioning accuracy while workpieces are picked up

Typical areas of application
• Handling of smooth to lightly rough workpieces, such as sheet Vacuum Grip- ping Systems
metal plates, cardboard, glass plates, plastic parts and wooden
boards
• In automated processes with short cycle times

Bellows Suction Cups
Bellows suction cups are used when it is necessary to compensate for varying workpiece heights, to handle parts with uneven surfaces
Vacuum Generators
or fragile parts. The bellows make this suction cup especially flexible and adaptable.
Advantages of bellows suction cups
• Good adaptation to uneven surfaces
• Lift effect while picking up
• Compensation of differences in height Technology
• Fragile workpieces are picked up gently Valve
Typical areas of application
• Handling of curved or uneven workpieces, such as body panels, Switches and
tubes, cardboard, etc. Monitoring
• Handling of fragile workpieces, such as electronic components,
injection molded plastic parts, etc.
• Handling of non-rigid or flexible workpieces, such as packaged
Filters and
or shrink wrapped products Connections

Suction Cup Materials
Application and ambient conditions are important for the selection of the right suction cup and the appropriate material.
Abrasion resistance, oil resistance and food safety are often required of a suction cup. These requirements can be met by selecting the
appropriate material.
