Custom silicone rubber types of vacuum suction cups

Different types of vacuum suction cups can be custom developed in silicone or rubber for particular handling arrangements. Compare the contact profile, installed height and connection rather than grouping cups only by diameter. Each feature affects how the component reaches and holds against the intended surface.

Begin with the usable pickup area on the workpiece. Then consider the approach direction and space for the body to deform. A profile that fits the surface may still require a different mounting height or release movement from another cup of the same width.

Choose the finished compound for the surface condition and cleaning routine. Evaluate the intended type with the complete vacuum equipment through pickup, movement and release. Keep variants identified by their working geometry when several forms are used in one machine. During replacement, inspect the old contact pattern for clues about alignment or interference. Selecting a new type should solve a defined contact requirement rather than simply substitute a shape that looks more flexible.

Material options

Custom silicone or rubber formulation; select the compound alongside the mating geometry.

Hardness selection

Silicone: 20–80 Shore A; solid rubber: 30–90 Shore A. Selecting a new type should solve a defined contact requirement rather than simply substitute a shape that looks more flexible.

Custom geometry

Compare the contact profile, installed height and connection rather than grouping cups only by diameter.

Fit evaluation

Evaluate the intended type with the complete vacuum equipment through pickup, movement and release.

Color & OEM

Custom colors; OEM markings outside the suction contact face.
