Custom Silicone Suction Cups

Silicone suction cups that grip smooth surfaces reliably — for mounting, hooks, holders and lifting tools, engineered for strong vacuum and long-lasting rebound.

Vacuum Gripping

Suction Cups That Hold Fast

A suction cup holds by creating a vacuum against a smooth surface. The cup geometry, hardness and surface finish all affect grip. We mold silicone suction cups that seal quickly, hold firmly and release cleanly, cycle after cycle.

  • Mounting & hook cups — for wall and glass use
  • Holder & lifting cups — for tools and accessories
  • Strong vacuum grip — optimized rim geometry
  • Food & baby-safe grades — FDA / LFGB compliant

Material & Performance

Choosing the Right O-Ring Material

Match the compound to your fluid, temperature and pressure environment.

RequirementRecommended gradeTypical hardness
Food & beverage contactFood-grade silicone (FDA / LFGB)50 – 60A
Medical / pharmaceuticalMedical-grade platinum-cured silicone40 – 50A
Industrial & hydraulicSolid silicone rubber (RoHS / REACH)60 – 70A
Fuel & solvent exposureFluorosilicone (FVMQ)60 – 75A

Compression Set

Compounds chosen for lasting elasticity, so the cup keeps its grip over repeated attach and release cycles.

Temperature Range

Rated from -40 °C to +230 °C depending on the compound selected.

Precision Fit

Mold cavities machined to ±0.01 mm, with finished-part tolerance confirmed during DFM.

Common Questions

Silicone Suction Cup FAQ

Most suction cups use Shore 40A–60A — soft enough to conform and seal against the surface, firm enough to hold vacuum without collapsing. We recommend a hardness for your load and surface.
Hold force depends on cup diameter, hardness, rim geometry and surface smoothness. Larger cups with an optimized rim hold more. We can mold cups sized and tuned for your load requirement.
Yes. We mold food-contact and baby-safe silicone suction cups tested for FDA 21 CFR and LFGB compliance, suitable for bowls, toys and feeding accessories.
MOQ is flexible and depends on size and cavity count. Small prototype batches are available for verification, with multi-cavity tooling for cost-effective volume production.
