MICRO-WIRE HEATING INSERTION

Viraver produces flat and curved glass with de-fogging or de-icing heating systems to ensure maximum visibility in all environmental conditions.

The heating effect can be obtained by using two different technologies; by inserting micro-wire heating elements or coating heating elements.

According to customer requirements, Viraver offers a wide range of design solutions to fully integrate the element according to the power supply, unitary heating power, electrical use as per component.

PROCESS

SAG BENDING

Viraver uses the sag bending technique to create large curved surfaces.
With this technology, even very thick sheets of glass can be bent, to form cylindrical and spherical curves, while retaining excellent optical properties and creating surfaces free of distortion and undulation.
The experience acquired in obtaining curvature, and using the 3D processing technique of the surfaces detected, allows our team to guarantee the continuity of the surfaces even in the most complex projects. Viraver’s larger new furnaces are able to bend glass sheets as large as 21.32ftx10.17ft (6,50mx3,10m).

CHEMICALLY STRENGTHENED GLASS / CHEMICAL STRENGTHING PROCESS

The chemical strengthening process of glass is used to improve the physical characteristics of glass, increasing its resistance to mechanical stresses and to thermal shocks.

The chemical strengthening process by its nature does not involve any kind of optical distortion and imprint on the treated glass.

The chemically strengthened glass is not subject to the risk of spontaneous rupture from inclusions of Nickel Sulphide and therefore does not require Heat Soak tests.

Viraver prides itself on being the only company to be able to produce chemically strengthened glass sheets as large as 26.4ftx10.53ft (8mx3,21m).

CLEAN ROOM ASSEMBLY

Laminated glass is one of the most used products in projects where glass is a structural part because it combines transparency with the robustness and security features required by standards and norms.
In Viraver lamination is executed for each piece of glass by bag technique and autoclave cycle.
The stratification techniques used in Viraver allows innumerable materials to be added to the plastic interlayer that further enhance the purpose to the glass, for example: heating elements, heat shields, electromagnetic radiation shields, electric and decorative opacifier films.

AUTOCLAVE LAMINATION

This is the process in which the union between the glass and the plastic material that make up the stratified takes place. In Viraver lamination is carried out lamination in an autoclave, which consists in subjecting the laminate to the simultaneous action of pressure, temperature and vacuum in order to generate the intimate union of the different materials. Viraver is equipped with a new large autoclave for glass and polycarbonate sheets equal to 29.53ftx10.83ft (9mx3,30m).

FINAL TESTING

Viraver has an ISO 9001: 2015 certified quality management system.
Viraver monitors all business processes in order to improve the effectiveness, efficiency and quality of its processes, products and services.
Viraver systematically controls its products before delivery with the aim to verify the customer’s standards, and in particular optical, foreign and sizes of products. The controls on the finished product are made by qualified national experts.
