Rubber cupping products use flexible cup materials to create suction during cupping therapy. This category includes natural rubber cupping sets and rubber-glass suction cups in different sizes and configurations for body, limb and facial applications.
Product Overview
Industrial rubber suction cups are vacuum gripping components used as the interface between automated handling systems and workpieces. They are designed for pick-and-place, transfer, positioning, and loading operations in robotic, pneumatic, and vacuum handling equipment.
Different cup geometries, elastomer compounds, sealing profiles, and connection configurations are available to accommodate variations in workpiece weight, surface condition, shape, temperature, and handling requirements.
Standard configurations cover general industrial handling, while application-specific options can be specified for oily surfaces, elevated temperatures, static-control requirements, and sensitive substrates.

Product Selection Guide
Selecting a suitable suction cup depends on the workpiece, vacuum system, operating environment, and handling motion.
Workpiece Surface: Smooth, textured, curved, porous, oily, coated, or sensitive surfaces.
Workpiece Shape: Flat, curved, irregular, recessed, or uneven geometries.
Workpiece Weight: Determines the required gripping area and number of suction cups.
Material: Select the elastomer according to temperature, oil, chemical exposure, and surface requirements.
Cup Geometry: Flat cups for suitable flat surfaces; bellows designs for height variation, angular compensation, or uneven surfaces.
Vacuum Level: Match the cup design and sealing characteristics to the available vacuum system.
Handling Speed: Higher acceleration and dynamic movement may require additional gripping points or suitable cup geometry.
Connection: Select threads, stems, or fittings according to the vacuum circuit and mounting interface.
Temperature: Select the compound according to the actual operating and cleaning temperatures.
Surface Sensitivity: Consider low-marking, low-migration, ESD-control, or other application-specific material requirements.
Automotive Manufacturing: Handling of metal stampings, glass components, trim parts, and other suitable workpieces during transfer and positioning operations. Oil-resistant compounds can be selected for applications involving oily metal surfaces.
Packaging Machinery: Pick-and-place and transfer of cartons, flexible packaging, wrapped products, and other suitable packaging materials. Cup geometry should be selected according to surface stiffness and porosity.
Electronics Assembly: Handling of electronic housings, panels, boards, and other components requiring controlled contact conditions. ESD-control configurations can be specified where static-control requirements apply.
Glass and Panel Handling: Transfer and positioning of suitable glass, coated panels, and composite sheets using cup geometries selected for the workpiece surface and curvature.
Woodworking and Furniture Production: Handling of MDF, timber panels, laminated boards, and finished surfaces where the workpiece characteristics are compatible with vacuum gripping.
Manufacturing and Quality Control
Elastomer Compounding:
Rubber compounds are prepared according to specified material formulations and application requirements. Batch identification can be maintained for production traceability where required.
Compression and Injection Molding:
Molded suction cups are produced using controlled molding processes selected according to compound and product geometry.
Post-Curing:
Selected silicone and other applicable compounds can undergo post-curing where required by the material specification and product application.
Dimensional Inspection:
Critical dimensions such as cup diameter, sealing-lip geometry, connection dimensions, and molded profiles are inspected against approved product drawings and specifications.
Mechanical and Vacuum Testing:
Product testing can include hardness, tensile properties, sealing performance, leakage characteristics, and fitting integrity according to the applicable product specification.
Batch Documentation:
Material and inspection records can be maintained according to product and order requirements.
Custom suction cups can be developed for applications where standard catalog configurations do not match the workpiece or vacuum system.
Custom Geometry: Cup diameter, lip profile, bellows structure, internal support features, and contact geometry can be developed according to application requirements.
Custom Compounds: Elastomer selection can be adapted for oil exposure, temperature, chemical resistance, static-control requirements, low-marking requirements, or other specified conditions.
Customized Connections: Thread specifications, stem dimensions, metal inserts, and mounting interfaces can be configured according to the customer's vacuum circuit.
Prototype Development: CAD drawings and technical requirements can be reviewed before tooling confirmation. Prototype and production lead times depend on product geometry, tooling complexity, material selection, and order requirements.
