Vacuum suction cups: vacuum driven which, once switched off, releases the suction cup from the object. The product range includes suction cups that adhere to curved surfaces, suction cups with internal and external threads, suction cups with 2 and 3 bellows and plate suction cups.
Pressure suction pads: these suction pads only need to be pressed against the surface to be stuck. An impulse of compressed air on the metal ball causes the object to be quickly detached. In addition, no additional clamping elements are required, a mounting flange is sufficient. If the ball is removed, they can be used as vacuum suction pads.
