Features

● Large inner support structure protects the metal sheets from deformation and damage during handling process.

● Slot structure efficiently increases the friction force between suction cup and workpiece in order to prevent the oily

   metal sheets from slipping during the handling process.

● 1.5 bellows structure has good sealing and buffer to workpiece with uneven surface.



Applications

●  Car stamping steel plate with irregular shapes, oily steel plate
●  Glass, stamping parts, plywood
●  Handling normal metal sheet (to avoid deformation)
