Speaking about household appliances, we often hear such concepts: “warranty”, “warranty seal”, “warranty repair conditions”, “damage to the seal” and “denial of service”. So what is it, what does it look like? How to avoid damage to the seal? In this article, we will analyze the questions presented and everything related to filling.
What is a warranty seal?
The seal is used in those places where prying eyes and hands should not get. Therefore, in order to avoid damage that cannot be restored, due to excessive user curiosity, they seal new equipment with warranty stickers. Why would the seller or manufacturer correct the mistakes that they did not make, but the end user, who, not knowing the subject, decided that he could fix or upgrade the device on his own. This greatly simplifies the task and reduces waste.
Where are seals used?
Seal, in fact, not only household and electronic equipment. The room is also sealed, which is not accessible to outsiders, and safes, and various books of accounts and records of materials, cash, mailboxes, ballot boxes and so on. The list of places where warranty seals are applied is quite large. Previously, the seals were wax, on the doors in the old administrative buildings you can still see the seal with plasticine filler, on top of which a seal is placed. But this method is not reliable enough. Warranty seals with a logo, with watermarks, a specific individual design and so on are now being made. All this allows not only to improve reliability against unauthorized hacking, but also adds a corporate identity.
Application specifics
First of all, warranty seals must fulfill their intended purpose - to hide from prying eyes what is under them. Whether it’s important information or the motherboard of a new computer, the owner of the seal must know for sure that everything has remained untouched. In addition, the seal should not prevent the user from performing actions with the device, which he has the right to apply at his discretion. That is, it cannot be a gigantic sticker or panel that will reliably close all access to the necessary ports and covers. Even better, if the warranty seal is invisible at first glance. In this case, an attempt of unauthorized access will not be possible to hide by sticking, coating or wiping traces.
Features and types
The properties that a warranty seal provides are determined by the material on which it is made. They should be clearly visible autopsy attempts. In some cases, especially in electronic products, seals have a special indicator that changes color if the equipment has been flooded or flooded. Since water for electrical engineering is very fatal, and warranty repair from your own pocket is not the most favorite accident for the manufacturer, such an indicator plays a huge role. Often, such seals are placed to not only protect the equipment from hacking, but also to clarify where it was bought.
Whether this device was really bought in this store or just the user decided to cheat. That is why the seals have a characteristic individual design. It is very important that it be difficult to fake, otherwise the whole point in its use is automatically reset.
Seal Production
The types of warranty seals are divided into three classifications: those that are made on the basis of paper, on the basis of film and combined seals. Paper based seals are resistant to temperature extremes and accidental mechanical damage. Tearing it off without deliberate impact is problematic. But under the influence of water, such a seal will collapse. Even if the wetting was insignificant and did not affect the internal structure of the equipment. Such seals are not recommended to be placed on objects that are stored in a room with high humidity or low temperature. At low temperatures, so-called condensate (water evaporation) forms, which destroys paper.
In this case, the use of a film is preferable. It is much less susceptible to destruction from water. But its minus is excessive elasticity and loose composition. It cannot be glued at the external joints of the equipment. The third option remains. Combination of paper and film backing. Such a seal has all the positive characteristics of both materials, and is devoid of their negative properties.
The seal does not immediately tighten to the surface. It takes about two hours. But after that it will be impossible to remove it without damage. But this makes it possible to correct the defect if the seal was originally glued incorrectly. The price of a universal seal will be slightly higher than that of one material, but it will fully pay off with quality at the output.
