Cleats prevent products from getting sucked in. They increase the retention force of the vacuum cup by enlarging the active suction area. The product is stabilized by enhancing the axial stability.
Cleats are particularly recommended for flexible products or in case of high acceleration forces in the machine, since the product is prevented from shifting or slipping.
Oval and rectangular vacuum cups are suitable for longitudinal or cylindrical work-pieces occupying low space (e.g. rails, framings, tubes and bolts). They are also suitable for corrugated work-pieces and products having bars and webs.
They offer considerably greater suction force compared to round vacuum cups having the same width
The use of vacuum cups at high temperatures is always dependent on the product and the time period in which the vacuum cup is in contact with the work-piece. In general, the following materials can be used:
Silicone: up to +200 °C
FKM: up to +200 °C
Thermalon®: up to +160 °C
HNBR yellow: for a short period up to +160 °C

The skill of creating a vacuum cup lies in finding the optimum ratio between material weight, centrifugal forces, friction and air flow underpressure during handling: and doing this afresh for every application.
Non-marking – this may well only be a theoretically achievable goal, but we pursue this aim as far as possible in the practice, and for every application. When selecting the material for our vacuum cups, we choose those which suit the respective thermal, physical and chemical conditions. The contact surface on the vacuum cup and the contact surface on the workpiece are optimally tailored to one another. This results in homogeneous contact surfaces whereby the material contact is restricted to the sealing function for the underpressure. This means our vacuum cups work almost exclusively using air – thus making them virtually non-marking.
We would be happy to assist you in finding the right material to suit your application. Please call us:

The demands on vacuum cups in the food industry range from the handling of already wrapped foods to the direct handling of unpacked food products. Due to the specific contour and texture of the products, they mostly require a distinct adjustment of the construction of vacuum cups. Specific requirements are also posed upon the material. Thus, in the food industry there should only be used vacuum cups whose material is FDA conformal. Mostly silicone is used.
To satisfy your individual demands concerning vacuum cups for the food industry we are pleased to help you find the right vacuum cup for your application. +49 89 962489-0
FIPA offers a wide product range of vacuum cups. Resistance against chemicals depends on several factors and varies from one material to another. We would be pleased to furnish information to you regarding the chemicals that various vacuum cups are resistant to.

The flat vacuum cups of FIPA offer lateral stability owing to their shape during the suction process and positional accuracy when depositing the products.
Additional cleats in the cup provide greater lateral strength and prevent flexible products from being sucked in and the vacuum cups from shifting or slipping in case of high acceleration forces.
Bellows vacuum cups are particularly suitable for sensitive materials having an uneven surface.
They facilitate easy level and angular compensation with varying product surfaces and pick up the product as soon as the vacuum is switched on.
The more folds that the vacuum cup has, the larger is the lifting movement and thus, the height compensation. However, the lateral stability reduces with the number of folds.
Bellows vacuum cups, hence, are recommended only for vertical handling of products.
In general, it may be said that the color of the vacuum cup is independent of the material. For example, silicone is available in several colors from transparent right up to red.
Conversely, you cannot draw any inference on the material of a vacuum cup from its color.
FIPA offers a very wide range of vacuum cups, which means that a large number of applications can be covered with the cups available in its standard product range.
If, however, a product calls for a non-standard geometry or consistency, the FIPA team would be pleased to advise you regarding the manufacture of a customised product for your company.
