Practical advice on choosing Attachments

In monitoring the quality of car windows should pay attention to the items listed below (for example, auto Bor Glassworks).

Edges

Surplus film between the panes. At the glass factory excess film after polymerization neatly trimmed.

Smooth surface on the edge. In the factory on the machines is a special edging.

Handicraft producers usually ignore these operations, because of what a fake "bad sits on the seat" in the window opening of the car. Such glass is only slightly processed, or rounded up to the edge of the oval. If you do not decide to run your hand along the perimeter of the glass because of the sharp edges of the product clearly, it is not a factory product and from its purchase of better abstain.

Thickness

Important role in the production of laminated glass has the thickness of the glass-blanks. She does not exceed 2,5 mm, and the collection of glass has a thickness from 5,6 mm to 6,2 mm (for cars). This is equal to the thickness of about four odnorublevym coins, folded together. Excess of this size or the presence of laminated layers of glass of different thickness are clearly speaks of the forgery.

Triplex handicraft production, from the use of poor-quality film and departures from the high-precision technology of its manufacture, it turns out not clear or distorted picture of the road. The photo below shows the appearance of air bubbles in the polymer layer.

Kant

In glasses, pasted in the window opening (VAZ-2110, "Gazelle"), around the edge of the inner side have to be a black edging. It serves for coupling the adhesive with the glass surface and is applied by silk-screen printing factory. At the point of the glass factory, which consists of piping, are located at equal distances from each other. On the counterfeit products are usually black edging slightly smeared and dismissed, the points are unevenly and can be stamped twice.

Sometimes the artisans applied black piping "Beauty" - you can see the "Lada", "Samara", "Volga" with piping along the openings, not only wind, but the side and rear windows. Factory, such glass is not available.

Packaging

To protect the edge of the windshield from being damaged during transportation and storage, the manufacturer is pasted on the side of the glass thin white paper tape. Lack exactly glued, easily removable, white tape indicates that the glass can be forged.

Marking

Most of the fake glasses will be issued for products Bor Glassworks as the most famous and guaranteed quality auto manufacturer. It can be used in labeling, can hardly be distinguished from the original, which is a direct deception of the buyer and a gross violation of Russia and international legislation.

Characteristic sign of inconsistency trademark Bor Glassworks - fake stamp.

The original glass "in black and transparent" shall contain: manufacturer's name in stylized letter "C" type of glass, signs of international homologation, the date of issue.

In considering counterfeits pasted glass you can find a stamp that does not match the factory, and the differences from the factory markings can be quite a lot.

The only exceptions are three-layered glass for ZIL-130 automobiles and buses: they have the stamp has a white color, instead of passing the mark homologation tests - a sign of Russia's compliance requirements.

In any case, you can conduct the following experiment: Take a coin and its edge with a slight effort to spend on the stamp. If it does not affect the die and at the glass, then with a high degree of confidence you can consider yourself the owner of the original factory glass. If the punch with this simple test or damaged by the seller when buying glasses strongly cautions you against this experiment - give up the purchase of such glass.
