Once the suction cup falls off, serious consequences will be caused.
As they are big suction cups, the mounted or adsorbed objects are very large or bulky. It is very important to check the airtightness before using the suction cups.Especially the industrial suction cups and heavy duty suction cup hooks.It is also necessary to confirm whether the weight of the adsorbed objects exceeds the adsorption capacity(safety factor must be ≥2). Since it cannot penetrate the surface of the sucker, it forces it to hold the sucker firmly to the surface.If the suction cup surface or edge is damaged and external air enters the suction cup, the suction cup will not work properly and will fall off. As the atmospheric pressure are always trying to keep its equilibrium, this pressure push the external air. Once squeeze the air out, it will turn into vacuum. When we use it, we need to force to press the sucker on the flat and smooth surface. The bottom of caps has a concave down area. RS have a great range of pneumatic products including suction cups and grippers suitable for every industry and application.The airtightness of material between Rubber and silicone suction cups are both good. Enhanced grip.Flat - suitable for glass, metal sheets and cardboard.Pneumatic suction cups are available in a range of shapes, sizes, diameters and designs and will handle most products. Absorbs any alignment problems.Deep - excellent with curved objects. This is measured in Newtons (N) and when looking for the right suction cup, ensure you choose one that will lift, move the weight and size of the object.What are suction cups made of?Suction cups are made from various materials like:SiliconeNitrilePolyurethane (PUR)FluororubberSilicone rubberSuction Cup Types AvailableBellows - ideal for concave and convex shapes. As soon as the atmospheric pressure is greater than the pressure between the object and the cup, atmospheric pressure presses the suction cup against the item, holding it firmly.What is holding force?Holding force is the amount of force required to move an object.

Before use check that the suction cup surface is clean and free from dirt or grit to ensure a maximum grip.Special grippers are sometimes used in tasks which suction cups cannot be used to handle delicate and brittle workpieces and are referred to as Bernoulli effect grippers.How do pneumatic suction cups work?When a suction cup contacts the surface of an object, it activates a vacuum generator (such as a blower, vacuum ejector or vacuum pump) that draws air from the space between the cup and the item. Suction cups will not work when there is a low atmospheric pressure.
The vacuum created enables you to move and lift any product. When pressure is put onto the suction cup it forces air out of the area, creating a vacuum. Suction cups are manufactured from a range of materials and perform well in many environments from light duty to heavy industrial.A suction cup works by having less air pressure on one side of the cup than the other side of the suction cup. Suction cups mould to the shape of the object they are handling without causing any damage. Pneumatic Suction Cups Pneumatic suction cups are also known as vacuum cups, vacuum pads and suckers and they can be attached to various surfaces to provide a safe and secure way to move and hold products.
