When transporting or storing various types of goods, it is necessary to ensure their safety and safety. For this, entrepreneurs, enterprises, various organizations and associations resort to different methods and methods.
Lead seals and their advantages
The simplest, most affordable and cheap is the use of such a method as lead seals. The main advantage of this method is its simplicity and low cost. After all, opening the seal without leaving any traces is impossible.
For a rather long time, lead seals are used to protect objects as a counter, door, a bag of collectors, cargo and passenger transport, equipment, cargo containers.
Seals have the form of metal disks (cylinders) of small sizes with two holes. A twisted wire or a special filling twine is pulled into the holes. On the back of the disk there is a niche for a knot.
All seals differ among themselves in these parameters:
Diameter (8, 10, 16 mm)
Form
Size
It all depends on the desire of the customer.
All seals, regardless of their parameters and purpose, perform the following functions:
Informational — it is impossible to remove seals without violating its condition. If there was an attempt to hack, it will immediately be noticeable
Power — in this case, a specialized device is used, which is opposed to an illegal attempt to hack
For the manufacture of lead seals, the primary brand of lead is used, which has been tested for toxicity and chemical composition. The melted lead is poured into forms where it cools and takes the shape of a disk or cone. Until recently, products were made by hand. At the moment, manual or semi -automatic machines or machines are used for the manufacture of seals.
Floors
The installation and fixing of seals is carried out using a special tool, which has the appearance of ticks and is called a flob for lead seals.
Plombriter is a power unit. Steel is used for its manufacture. All seals, regardless of their use, consist of two removable dies, on which a special print is applied (engraving).
With a strong press of the seal of the seal on the lead seal, a clear print remains on its both sides.
To increase the reliability of protecting the lead seal, engraving on the seal dies, they make a rather complicated. For example, in addition to a certain code, there may be an image of wise drawings or figures.
The integrity of the seal on a sealed load or object is checked by a special person. He must certainly know all the distinctive features of the picture on the lead seal.
In the manufacture of seals, precisely removable dies are used. This is necessary to change when changing the pattern of the print on the dick. Nippers are usually removable or plastic. As it is already understood, the manufacture of sealing requires an individual approach to each customer.
Two types of strap engraving are used:
Brought — the simplest and most affordable type of type
Convex — a more complex and time -consuming type of engraving on the dick. This type of engraving guarantees maximum protection
Despite the quite long time using lead seals, they remain relevant and today.
