Features
● Large bottom area support structure, prevent permanent deformation of thin workpiece.
● Special liner structure could overcome the self-adhesion between thin sheets.
● Small internal volume, short operation cycle.
● Double sealing lip has good sealing performance and large suction.
● Rubber parts can be replaced separately, greatly reduce customer cost.
Application
● Workpiece with smooth or slightly rough surface
● Wood
● Metal sheet
● Heavy workpiece

◇Note: Testing vacuum level:-60Kpa. Workpiece with smooth and clean surface. The data of pull-out force as above are figured out without considering safety factor. The data may be different according to different workpiece surface. It is recommended that the vacuum pipeline should be as short as possible and not longer than 2m.

◇Note: 1. Dimension tolerance should meet the requirements of GBT3672.1-2002-1 M3 rubber product dimension tolerance standard.
2. Dmax is external diameter of the suction cup when it is fully compressed.

◇Note: Contact inductive valve (EB)
When the suction cup doesn't contact the workpiece, the contact inductive valve closes the vacuum port, to prevent the vacuum flow leakage.
When the suction cup contact the workpiece, compress the valve rod of the inductive valve, the vacuum port opens and the suction cup works normally.
