Construction works for the new Vuototecnica headquarters are on schedule to be completed by the end of 2010. In early 2011 the new headquarters will be inaugurated so please stay tuned!

It’s the new PVP 05 single-stage vacuum generator. Its distinctive feature is the particularly reduced size compared to the performance it offers.

Vuototecnica has designed and created it for all applications requiring extremely compact equipment.

The new PVP 05 vacuum generator operation is based on the Venturi principle, and it is especially suitable for controlling vacuum cups, gripping and handling non-porous objects and equipment with limited capacity.

Anthropomorphic robots and palletising systems manufacturers require increasingly flexible vacuum gripping systems.

Vuototecnica meets this requirement of extreme lightness with the new OCTOPUS gripping bars made of polizene, a plastic material that reduces the overall weight by 40% compared to the traditional aluminium ones.

In this new solution, the base box and fastening plate are made of polizene, while the suction plate is made of aluminium, either in the microperforated version or equipped with shut-off valves.

The new Octopus polizene gripping bars maintain all the strong points of traditional aluminium bars and are based on the same operating principle.

Thanks to their extreme flexibility, Octopus vacuum gripping bars can operate correctly either vertically, horizontally, tilted or upside down to the gripping surface and allow gripping objects of any shape or size, provided that they do not have an excessive transpiration, without having to change or replace vacuum cups, even when their surface occupies only 5 ÷ 10 % of the entire suction plate.

Construction works for the new Vuototecnica headquarters are rapidly continuing.

At seven months from the start of these works, the structure of the new building, an area of over 4000 sqm that will house offices, research laboratories, a learning area and a permanent showroom, already stands in Via Olgiate Molgora.

The new headquarters, which will be inaugurated in 2011, is being built according to state of the art eco-compatibility and energy savings criteria.

Interfluid (www.interfluid.it) knows it well. This company based in is the exclusive distributor of Vuototecnica products in the area of Varese.

A choice that has proved to be rewarding in a macroeconomic context marked by deep world recession, as stated by sales manager, Gianpaolo Sala:

In the past, we have purchased Vuototecnica products to complete the applications required by our clients. Therefore, we considered vacuum products as integration to our core business: pneumatics.

With the arrival of a new sales force in our company, we have reconsidered the position of Vuototecnica products, opting for a new strategy investing on their large scale promotion. At the same time, Vuototecnica’s constant strive for innovation, presenting new technical and commercial initiatives, has favoured the development of new products that allow us today to be on the market always up-to-date.

What are the results of this collaboration as of today?

The simultaneous innovative situations have started a remarkably positive sales trend. Turnover has quadrupled and hasn’t decreased not even in this time of crisis.

How has the relationship between you and your clients changed given the type of service offered?

With the mutual collaboration agreement we do our job with more resolve, knowing that we are working for the present but we are also investing in the future.

Vuototecnica assists us in difficult commercial negotiations and supports us with top quality technical assistance, allowing our clients to carry out tests at their laboratories and testing rooms, thereby putting their forty-year experience at our disposal.

There are situations in which the use of an instrument able to provide an accurate signal once a certain vacuum level has been reached is recommended for safety purposes; such situations include the starting of a work cycle, or checking the grip of suction cups, etc.

Vuototecnica designs and manufactures several vacuum measurement and regulation systems. Among these are micro digital vacuum switches that are able to provide a very accurate digital signal at the maximum measurement value set. Its moderate dimensions are especially suitable for installations near suctions or where the vacuum distribution is confined to very limited spaces.

AVG series vacuum generators, designed specifically for the automotive sector, are already set for micro vacuum switch installation when supplied.

The digital micro vacuum switches supplied by Vuototecnica have a commutation point, included within the scale value that is easily programmable using an adjustment screw located on the upper side of the device; a red LED near the screw indicates the commutation status of the digital output signal.

The pressure differential (hysteresis) between the set maximum value and the reset value of the rest signal, is equal to 2% of set value and cannot be adjusted.

The solutions most often used are not always the most advantageous.
Vuototecnica has always been involved in researching new, innovative solutions to improve industrial processes. In this context, the pneumatic vacuum suction pump represents a real evolution compared to traditional electric rotary vane pumps.

For an “on field” evaluation of the advantages of using this vacuum pump, we went to Essepi srl (www.essepicompensati.it), a company that produces plywood and multi-layer components for the chair, furniture and home furnishing industries.
The company chose to install, on a 4-axis work station, the PA140 pneumatic vacuum suction pump created by Vuototecnica, to replace the classic oil bath rotary vane vacuum pump that is commonly used.

We met with Michele Basin, Manager of Essepi’s Technical Office:
“’The yield of the new PA140 pump is absolutely amazing. With this simple and compact device, we are able to obtain the same vacuum level as a classic oil bath pump, eliminating all wear and maintenance problems once and for all.

We asked ourselves: “Why didn’t we discover this device earlier?!? We would have saved a few thousand euros and all the machine downtime resulting from maintenance and the repair of old pumps.

Frankly, we wonder why the manufacturers of CNC machines do not provide the P140 suction pump instead of the usual very expensive vacuum pumps. Its initial vacuum starting power is greater and allows for the instant locking of pieces such as bodies, which have uneven surface curvatures.

Could the Vuototecnica vacuum suction pump also be an ideal solution for your other machines?

‘Without a doubt we will gradually replace the old vacuum pumps with the PA140 on all of our machines. Ultimately, the device costs basically the same as a complete maintenance operation of the old pumps, and vane replacement’.

Vuototecnica has specially designed the new DR 100 M 01/02 system for vacuum resin infusion moulding for the nautical sector.
Shipyards usually operate with ordinary vacuum pumps that suck onto the moulds without the interposition neither of a volume nor of a vacuum reducer to adjust and maintain the depression inside the suction circuit constant. The result is a variety of permanently operating pumps with the risk of overheating and the need for constant maintenance.
To solve these problems, Vuototecnica has developed this mobile system, which guarantees the best finishing in operations such as infusion or vacuum bagging, thereby ensuring maximum flexibility as required in shipyards.
The resin, which is contained in a special container, is vacuum-sucked by the Vuototecnica mobile system onto a mould until filling it.
Any excessive resin collected inside the sheet steel autoclave can be viewed through the transparent methacrylate cover, which can be manually removed for cleaning the inside of the autoclave once the process is completed.
The installed oil bath vacuum pumps (MV20A/MV40A) allow reaching a maximum vacuum level of 99.5% inside the autoclave therefore, the equipment can also be used as a degasifier.
The standard vacuum reducer installed on the equipment allows adjusting the vacuum level between minimum 20% and maximum 99.9%. (more…)

The Automotive sector increasingly requires equipment with excellent performances and limited weight and bulk. In order to meet these requirements, Vuototecnica, in close collaboration with the engineering departments of the major automobile companies, has created the new Automotive Vacuum Generators (AVG).
They are equipped with single ejectors that, given the same capacity of generators with multiple ejectors, allow generating vacuum more rapidly with an instant grip by the vacuum cups (Maxigrip Cups) as a result.
The standard equipment also includes a device that guarantees 40% energy saving in terms of air consumption, compared to traditional vacuum generators. All this thanks to the built-in standard pneumatic vacuum switch, which interrupts the compressed air supply once the preset maximum vacuum value is reached and restores it only when the vacuum level returns below the minimum threshold. All this not only allows maintaining the vacuum level within preset safety values, but also a considerable saving of compressed air.
The unique AVG design allows the equipment to operate in “Energy Saving” mode, as indicated above, even in total absence of electricity. This is an essential factor in the robotic lines of the automotive industry in case of sudden downtime or blackouts. The standard Venturi pipes installed on the robot grippers are constantly controlled by a normally open pneumatic valve for the entire time the electricity is absent to prevent the loss of the metal sheets or the windows of the automobile in the assembly line. An energy consumption that is unacceptable for lines equipped with hundreds of Venturi pipes can be easily solved using Automotive Vacuum Generators.
Once the work cycle is completed, the power supply micro solenoid valve is deactivated by means of an electrical pulse while, at the same time, the ejection solenoid valve is activated for quick restoration of the atmospheric pressure inside the vacuum cups.
AVG vacuum generators are set for the installation of a digital micro-switch.

Interview with Davide Bosi, Technical Sales Manager for Vuototecnica

What is the state of the art in vacuum technologies in the field of energy saving?
Designing and creating solutions that allow saving energy is a must. In fact, on one hand, it allows considerably reducing production costs, mainly in all those industrial processes where primary energy has a high cost, while on the other; it contributes to promoting environmental sustainability.
