Common vacuum suction cups include: flat suction cups, bellows suction cups, oval suction cups, and special-purpose suction cups.

1.Flat Suction Cups

Features:

  • High positioning accuracy
  • Compact design with minimal internal volume to reduce gripping time
  • Capable of withstanding high lateral forces
  • Wide sealing lip ensures optimal sealing on flat surfaces
  • Excellent stability when gripping workpieces
  • Embedded structure (e.g., disc-shaped design) enables high suction force
  • Base support for added stability
  • Available in large diameters for higher efficiency
  • Diverse material options

Typical Applications:
Handling flat or slightly curved workpieces such as metal sheets, cardboard boxes, glass panels, plastic parts, and wooden boards with smooth or mildly rough surfaces.

2. Bellows Suction Cups

Features:

  • Available in 1.5, 2.5, and 3.5 convolutions (folds)
  • Adapts well to uneven surfaces
  • Provides lifting motion during gripping
  • Compensates for height variations
  • Gentle handling of delicate workpieces
  • Soft bottom convolutions
  • Rigid upper convolutions and shank
  • Versatile tapered sealing lip
  • Base support
  • Multiple material options

Typical Applications:
Transporting uneven or contoured workpieces like automotive metal sheets, cartons, plastic components, foil/thermoformed packaging, and electronic parts.

3. Oval Suction Cups

Features:

  • Maximized effective suction surface
  • Ideal for long, convex workpieces
  • Increased rigidity for enhanced performance
  • High suction force in compact sizes
  • Combines versatility of flat and bellows cups
  • Multiple material choices
  • Embedded structure delivers strong suction

Typical Applications:
Handling elongated workpieces with small contact areas, such as pipes, geometric components, wooden slats, window frames, cartons, and foil/thermoformed packaging.

4.Special-Purpose Suction Cups

Features:

  • Retains general functionality of standard cups
  • Custom materials and shapes for specific industrial applications

Typical Applications:
Handling specialized workpieces with unique properties (e.g., fragile, porous, or deformable surfaces).
