Features

◇ Large inner support structure protects the sheet metal from deformation and damage during the handling process.
◇ Slot structure efficiently improves the friction force between vacuum pad and workpiece in order to prevent the 
   oily sheet metal from slipping during the handling process.
◇ 1.5 bellows structure has good sealing and buffer to workpiece with uneven surface.
◇ Oval suction cup is more suitable for long and narrow workpiece with flat surface and curved surface.



Applications

◇ Car stamped steel plate, oily steel plate
◇ Long and thin workpiece with slightly curved surface
