Matrix Cups

These Suction cups have been created as an alternative to the ordinary cups used in the robot-automotive field and they offer an excellent solution to gripping and handling problems that could arise on vacuum-driven handlers in every industry sector.
They can be both flat and bellow-type, round and oval and equipped with support.
The extremely flexible outside lip, can be associated with the typical features of the bellow cups, allow them to adapt themselves on flat, concave and convex surfaces with no risk of deforming or breaking even the thinnest objects to be handled.
The innovative design of the inside of the cups, which facilitates the drainage of oil and water, ensures a high friction coefficient with the gripping surface and, in particular, a unique grip on oil-covered metal sheets or wet glass or marble sheets.
This particular feature guarantees a firm grip and, therefore, an accurate placemet of the load to be handled.
The MAXIGRIP standard vacuum cups are made with our exclusive BENZ compound:
- Hardness 60÷75°Sh
- Working temperature between -40 and +170 °C
- Stain-resistant
- Excellent resistance to abrasion, water and to oils containing chlorine
Their galvanised steel support is vulcanised onto the cup. A wide range of accessories, such as adapters, couplers and articulated joints, allows them to be installed on any vacuum-driven handler.
Because of their universality of use, these cups can also be provided in special compounds.

• Developed to “bite” the most oiled steel plates • Available in many shapes and sizes, for any handling requirements • Made from our exclusive Benz compound • Equipped with the keepers used in the Automotive field: articulated joints with axial vacuum connections, reductions and adapters

Circular rim cups

These cups have been designed for lifting objects with a central hole.
Their very thin lip allow them to grip very rough surfaces, such as grinding wheels and discs.
They are particularly recommended for handling CDs, perforated discs, toothed wheels, pulleys and other similar objects. Their supports are made with anodised aluminium and are provided with a threaded hole in the centre to allow suction, as well as its fastening to the machine.
The cups are cold-assembled onto them, with no adhesives. To guarantee maximum flexibility, the cups for gripping grinding discs are made with natural para rubber N, while those for handling CDs are made with silicon S.
Cups in special compounds shown on top can be provided upon request in minimum quantities to be defined in the order. For the spare part, all you have to do is request the cup indicated in the table in the desired compound.

• Suitable for gripping grinding discs, CDs and objects with a central hole • Available in all standard compounds and in special compounds upon request • Their supports are made with anodised aluminium and are provided with a threaded hole in the centre to allow suction and to fasten it to the machine • The cups are cold-assembled onto the supports without using adhesives

Vacuum cups with nonslip support

These cups share the same technical and mechanical features with the ones described above, but their support has a special non-slip plastic coating that make them particularly suited for clamping glass and smooth marble.
A built-in stainless steel mesh filter in the suction hole and an O-ring seal at the base of their support are the other main features of these cups.
They are also provided with two or for housings for TCCE screws, according to their size, for fixing them to the workstation.

• Vacuum cups for clamping glass and smooth marble • Aluminium support with nonslip plastic coating • Built-in stainless steel mesh filter • Seal at the base of the support to ensure tightness between the gripping plane and the support itself • Available in standard compounds and stain-resistant Biond, they are cold-assembled onto the support

Vacuum cups with ball valve and selflocking support

Glass machinery manufacturers require increasingly accurate and safe clamping machines. This has led us to the creation of this series of cups. The specially designed shape of this cup guarantees a firm grip. The other main feature is the utmost precision in the height, whose nominal size has a tolerance of only five hundredths of millimetre. They are composed of:
- A sturdy anodised aluminium support with a wide surface at the base limited by a seal whose purpose is to fix it to the bearing surface.
- A standard rectangular flat cup which is cold-assembled onto the upper part of the support for gripping the load.
- A ball valve that opens up creating vacuum, only when activated by the load to be gripped.
- Two quick couplings for vacuum connection.
The detection of vacuum, for gripping and releasing the support, can be made via three-way vacuum valves or solenoid valves.

• Vacuum cups for clamping glass on work stations • Ball valve activated by the load to be gripped • Aluminium vacuum self-locking support • Release button for placing the support even with the vacuum inserted • Round or rectangular flat nitrile rubber cup vulcanised on its metal support • Height tolerance within 5 hundredth of mm • Quick couplings for vacuum connection

Bernoulli cups

Vuototecnica research has led to the creation of a new range of vacuum cups based on Bernoulli’s principle.
These new vacuum cups are ideal for handling, without any contact, fragile, uneven or microperforated objects, such as semiconductor platelets, silicon disks, solar cells, precious metal plates, films and whatever else needs to be handled with extreme care.
They are made of anodised aluminium with a stainless steel disc.
The antistatic silicone spacers located on the vacuum cup gripping surface prevent transverse movements of the object to be handled.
Compressed air supply connections can be either axial or radial and the quick coupler for the external hose with a diameter of 4mm is included in the package. Unused holes are closed with brass threaded plugs. 3 or 4 threaded holes on the rear of the vacuum cup allow fastening them to the machine.

• Based on Bernoulli’s theorem, these cups allow gripping fragile objects with no contact between the cup and the object itself • Ideal for handling silica discs, solar cells, semiconductor plates, films, biscuits, etc. • They are made with anodised aluminium and have a stainless steel centre thrust disc and antistatic silicon spacers • Compressed air supply connections can be axial and radial
