Features

● Large inner support structure protects the metal sheet from deformation and damage during the handling process.
Slot structure efficiently improves the friction force between suction cup and workpiece in order to prevent the oily 

   metal sheet 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 stamping steel plate, oily steel plate
Long and narrow workpiece with slightly curved surface
