Production of plastic money
Every year all over the world it is manufactured 100 billion notes, and to the charge goes even more. The total sum of all notes in use compounds 1 billion bucks. But all misfortune that this money longly does not live. Mean life span of the note hardly is more than year. Also that is rather light mode of their counterfeit even worse. As to create rather perpetually note from which one it is possible to do all and only it is impossible to forge?
The Australian Melbourn, here money have ceased to be for a long time dirty. Having faced a double problem, at first - a short life of notes, and secondly appreciable development of methods of production of a counterfeit money, the Australian Reserve bank has decided a radical method to destroy tradition. In 1988 experiment with in essence new note which one cannot be spoilt literally there has started. Have made it of plastic material. It was such success, it became popular worldwide - from New Zealand to Nepal.
Production of plastic money starts with a small pellets of a polymetric compound. Tiny globules are melted on top part of a huge metal tubing and the show of incident melted polymeric mass appears. On the way the fluid is chilled by water trickles.
The Special automaton inflates huge polymeric bladder, by altitude about the 5-storeyed dwelling. While bladder is under the necessary pression - its sides always one width. In total this huge bladder is stretched on 20 metres. For the lower part of bladder a polymetric compound roll in rollers and it becomes similar to sticky surface slick. Whether by means of the infrared metre of breadth and a strip correct width for surface slick is mustered. The polymeric pages roll in rollers, each of which presents 8 km of surface slick and 1,5 tons weigh. Now after plastic film building there is one more problem how on plastic material to plot a paint so that it was not deleted at all?
For a solution of a problem the heavy-lift press and very colorfast paint is necessary. On each side of a leaf plot to 5 stratums of a white paint, creating a mat clammy surface on which one it is possible to plot a figure. On each note there should be a small transparent window, the availability of such windows on surface slick is mustered special pulsing spark. It is one of general performances of the plastic note because the main member of protection against counterfeits here will be had.
At a following stage in the special scoop in these windows the map ensuring protection against counterfeits eats. On each window the laser plots on 5 tiny maps with velocity of 20 billion processes per second. These maps are very similar to the hologramme image except that it can be projected by means of the laser pointer and through it it is possible to look at light. Such thing is very complicated for forging.
Further the polymetric compound is slited on pages, they are almost off-the shelf to a following phase of production - to figure plotting. At first the special automaton plots background colours on two sides of the note. The following press plots the next coat of paint, the relief figures and separate thin parts. Because of miscellaneous width of a layer blackened a note surface becomes irregular, finned and it begins lighter to distinguish from a counterfeit.
Process of building of notes is almost completed, but on them there is no one relevant unit of protection against a counterfeit - a unique serial number. Manually, on the numerator the first figure of the next series of notes and now the rig is advanced is off-the shelf to start printing of serial numbers.
