The moons have very important functions in vehicles, being the elements that are responsible for protecting us from external agents; avoid crushing the passenger compartment in case of overturning, maintaining a comfortable temperature inside the passenger compartment and causing the least possible damage to the vehicle. The manufacture of these crystals requires various production processes to achieve the aforementioned properties you can visit this site to know more about it.

The production process:

The origin of the materials that make up the glass of the vehicles comes from a combination of silica sand and metal oxides, which are heated to the melting point. As a result, a liquid is obtained which will solidify into sheets and be classified taking into account the type of glass: tempered or laminated. According to current legislation, laminated glass must be used in the manufacture of windshields, while tempered glass is used for all other windows such as the windows of the doors, the custody, the roof and the rear windows.

Tempered glass:

This typology is characterized by a production process in which the glass is heated up to 600ºC, to be cooled with air quickly and in a matter of seconds. This process facilitates the solidification of the product giving it a greater mechanical resistance than a normal glass. However, its most significant feature has to do with our safety in case of accident or impact. If it breaks, the fragments resulting from the tempered glass are multiple, small and round, so that they do not cause serious injury to the occupants of the vehicle.

Laminated glass:

This type of glass is formed by two sheets of glass and between them a transparent sheet called PVB (polyvinyl butyral). It is a polymer of great adhesion and durability that is responsible for keeping fragments of glass inside the windshield, offering greater resistance to the entry of external elements and avoiding injuries caused by a possible breakage in the event of an accident or collision. The manufacturing process of this type of glass consists of three phases:

Cut and screen: the glass is cut according to the model and the desired dimensions. After cutting, the edges are milled, each piece is washed and dried to proceed to the next step.

Molding: both glass sheets are introduced into an oven, where, after heating, the material becomes more flexible and moldable. At that point, the corresponding curvature is started for each vehicle model.

Assembly: when the glass has cooled, insert the PVB interlayer and after this step, it is heated again, in order that the three sheets form a single.

Other features:

Thanks to technological advances, vehicle glass has evolved significantly in recent years, being lighter and incorporating systems that offer greater comfort and safety, reducing fuel consumption and pollution, such as: athermic (reducing the creation of heat ), antireflection (reducing the reflection of light), acoustic (weakening the penetration of outside noise inside), hydrophobic (better draining the water), dyed (absorbing part of the solar energy), with solar control (allowing darken or Illuminate the shade of the glass),heat (heated) and system HUD (virtual screen information on the windscreen).

As we have seen, the moons of the cars play a very important role in our safety and comfort, and therefore, whenever any problem is always convenient to go to an expert in the field. Trust us for repair and replacement of moons and enjoy the advantages of quiet travel to anywhere.
