Custom molded vacuum glass sucker/suction cup

A glass suction cup needs a suitable contact area on the actual glass, including any coating, texture, or curvature present. A smooth looking panel can still have a feature beneath the rim that interrupts contact. The cup profile and mounting arrangement should be assessed together with the load direction and movement of the complete application.

Check the usable surface around the entire footprint and keep the attachment from tipping the cup toward one edge. Where vacuum equipment is used, include its operating and release arrangement in the assessment. The rubber component alone does not establish a lifting capacity for a glass handling assembly.

Clean the rim and glass by a method appropriate to their materials before fitting. Inspect for cuts in the lip and verify it sits evenly. Release the cup as intended rather than levering an attached component away from one side. During reuse, examine repeated wear against the contact location and handling path so a replacement is not immediately subjected to the same scraping or edge lifting condition.

Material options

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

Hardness selection

Solid rubber options: 30–90 Shore A. The cup profile and mounting arrangement should be assessed together with the load direction and movement of the complete application.
