- Foam Rings for VSA & VS Suction Cups, VSBM series
-
-
- Applications
- The foam ring is designed for gripping products with an uneven or ridged surface, e.g.
. Sawn wood, sheet metal, fl at surfaces with bumps or hollows.
. All granular surfaces to which suction cups cannot adhere correctly and therefore cannot be airtight.
- Operating Characteristics of the Materials
- • Nitrile (NBR - Black)
5 or 10mm thick, depending on the diameters of the suction cups. Good resistance to oil. The nitrile foam strip can only be bonded to nitrile suction cups.
• Silicone (SI - White non Food-grade silicone, SIF White Food-grade silicone FDA Standard)
2 or 5 mm thick, depending on the diameters of the suction cups. Heat-resistant up to 160°C, does not leave marks on products handled. Do not use the silicone foam strip for gripping products before painting or lacquering. The silicone foam strip can only be bonded onto silicone suction cups (bonding is guaranteed if it is carried out in the factory).
• Mounting
The foam rings are mounted by bonding. In all cases, this should be performed in our factory as we have the adhesives adapted to the materials. It is essential that bonding of silicone be carried out in the COVAL factory.
