Flexible materials wrinkle, causing large leak paths. The cup and the vacuum generator must be sized to accommodate that leak rate. The bore of the fitting must be close to a 1:2 ratio to the diameter of the cup. Typically, handling flexible materials does not involve heavy weights. Calculating cup holding force is not required. Choose a cup with a very thin flexible lip to ensure the cup conforms to the wrinkled material. Multi-bellows cups work well in these applications because of their flexibility. The interaction between the vacuum cup and the flexible material is critical. Because the leakage flow rates are so high, it is necessary to use our NCDF Series of high flow (air amplifier) vacuum generators. With so many variables affecting performance, Norgren strongly suggests that a sample of the material be sent to our in-house test facility for a generator and cup recommendation.
