Perforated plates are nothing but sheets available in different materials, usually very resistant, in which there are a series of
regular holes of different shapes, sizes, spacings and patterns.
The drilling is obtained through a cold shearing of the metal, thanks to the use of a series of punches used inside a press, where the plate to be drilled is put.
By varying the matrix of the punches or even of every single punch, it is possible to obtain holes of different shapes. This happens also for the size: we can have in fact from large to very
small holes (microperforated sheets) with a diameter as small as 0.3 mm.
Unlike the holes obtain
ed by a simple drill, perforated plates have a series of features that improve their
quality:
- Absence of residues
- Accuracy in size and distance between holes
- Respect for the basic scheme
- Possibility to obtain different shapes with high precision
Perforated metal sheets thus obtained are used in practical industrial manufacturing sectors such as: machinery and equipment construction ,
furniture, industrial filtration, construction, air conditioning, automotive, exhibitions and railings.
As said, the materials used must be resistant. For this reason, the most used in the construction of perforated plates are stainless steel and other special steels, aluminum alloys, zinc,
titanium, brass, copper. If necessary, however you can get the same results with plastics.
Usually the standard size of a perforated sheet is 1000x2000mm. The thickness ranges from 0.2 to 15mm instead. However, according to the demands of the customer you can also get the perforated
plates with different characteristics than the standard.
Have a look at this video in order to see differant perforated sheets' patterns:

After a 2009 to forget, the Italian industry, manufacturer of machine tools, robots, laser marking and automation, in 2010, has
taken the road to recovery.But recovery seems to be difficult. This is what emerged during the year-end press conference of the Association of Italian manufacturers of machine tools, robots,
automation and accessory products.
As shown by the data, in 2010, the Italian production has grown to 4.23 billion euro, marking an increase of 3.3% over the previous year. The modest turnaround, which has enabled manufacturers to
recover less than a tenth of the ground lost in 2009, is an expression of apathy that has affected almost all markets indiscriminately for about two years. To confirm this, the Italian machine
tool exports grew in 2010, only 3.1%, to 2.605 billion euro. With regard to the first nine months of the year, the first export market of the Italian industry was China, that has overtaken
Germany from the podium. At the third place we find the U.S., followed by France, India, Russia, Iran, Brazil, Spain, Poland. Given the backlog of sales in traditional markets of the made
in Italy such as Germany, the United States and France, the Italian manufacturers have seen sales grow in India, Russia, Iran, Brazil.
The 2011 forecasts show an improvement trend that is still rather weak. 
Despite the major economic indicators mark the rebound, the increase in 2010 and in 2011 still looks pretty weak. What worries most Italian manufacturers of machine tools is the weakness of the
internal market and in general of the European Union. According to a recent survey, over 25% of the machines installed in Italy and in Europe, has over twenty years. Upgrading of production in
the structures is therefore a must in order to prevent the loss of manufacturing competitiveness over supply of foreign competitors, most notably the Asian player of the area. Therefore it
would be necessary to introduce a system of incentives to scrap used machine tools for sale.

RFID, acronym of Radio Frequency Identification is a technology which permits to identify goods, animals or people in an automatic way. The system works thanks to the reading of informations
contained in a tag at a distance through the use to RFID readers.
A tag RFID is made of a microchip containing data (among which an unambiguous and universal number written in the siliceous) and an antenna. Sometimes it can also have a battery.
A tag can receive and transmit via radio frequency the informations contained in the a tranceiver RFID.
In the last years, the automatic identification system (auto ID) has generated much interest and it's spreading in every industrial field, like logistics and goods handling, manufacturing
sector and also industrial laundry (where it 's useful to manage the
sorting systems for laundries)
RFID technology is considered a general purpose technology due to its high application potentiality (like electricity and wheel) and it presents an elevated level of pervasion, which means that
once an application is found in a specific point of the chain, its application and benefits quickly spread on the whole chain.

Oil hydraulics success reached in several fields since 1960 is mainly due to the many advantages offered by this technology , combining tremendous force concentrations with excellent control and
regulation capacities.
Electromagnetic transmissions have been replaced by oil hydraulic systems, thanks to which elegant and efficient solutions can be managed to solve even considerably difficult problems, that once
were considered unsolvable.
Complex projects like petrol perforations in strong depth, great engineering works, siderurgy, aeronautics, have been realized thanks to its combination with electronics.
But like many other force transmission systems, oil hydraulics has limits and counter indications, that must be considered while planning the initial project:
First of all the total rendering of transmission is inferior than mechanical and electromechanical transmission.
Secondly, contemporary feed of parallel actuators requires particular circuit devices.
Third thing, the liquid pressurization, even if limited, can influence the precision of mouvements, especially in case of big plants working at high pressure.

Automation is the technique through which, in a generic production process, the human being is replaced by the machine.
Automation has been introduced in production cycles for several reasons:
* the reduction of work costs;
* the increase of productivity;
* trade unions conflicts;
* dangerous, monotone and heavy working;
* improving of the quality of the product.
The main advantages of automation on production processes are:
* productivity increase;
* reduction of product supply between on phase of the process and the following;
* improving of the quality of the product
* decrease of mistakes.
Among the main disadvantages and inconveniences caused by automation we can name:
* more expensive investments
* costs of company renovation
The impact of automation of production processes on the kind of work made by both human beings and machines have been and is remarkable. Automation in fact, thanks to the use of electronics and
informatics, not only has changed the job performed by the human being but it has also change his philosophy.
Automation delegates to to automates machines all repetitive, manual and dangerous works while more intellectual works are addressed to human being.
