CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
2 companies list this product among what they make. Company figures are quoted from each company's own website; every card states where the relationship came from.
Manufacturer listings support early research and capability understanding. They are not certification, ranking, or transaction guarantees.
Vacuum cups work best on smooth, non-porous surfaces like glass, metal, plastic, and coated materials. They can handle slightly curved surfaces but struggle with highly porous, rough, or oily surfaces without special adaptations.
Calculate based on object weight, safety factor (typically 2-4x), vacuum level, and surface conditions. Formula: Cup diameter = √(4 × Weight × Safety Factor / (π × Vacuum Pressure × Friction Coefficient)).
Regular inspection for wear, cracks, or contamination; cleaning of sealing surfaces; replacement when hardness increases by 10 Shore points or visible damage occurs; checking vacuum lines for leaks.
