At the end of 2008, our glass plate cutting moved to a new hall, in which our colleagues use the most modern Lisec cutting line in order to be able to serve our Customers faster and in greater quantity than ever. Maximal plate size: 3210*6000 mm
The edge finishing of glasses is need for aesthetic and security aspects, and it is a prerequisite of certain further technologies. Our machines are modern, semiautomatic, straight and shaped edge polishers.
For the increase of the load capacity of the glass pane we use thermal tempering which is done in the tempering oven developed for this purpose. The thermal tempered security glass is a glass in which we create remaining surface shear stress with regulated heating and cooling technique in order to greatly increase the mechanical and thermal stress resistance of the glass. Compared to normal glass, the bearing capacity of tempered glass will be almost 7 times higher. Maximal tempering size: 4500*2450 mm
The method of creating fused decorative glasses is that the glass is elaborated in high temperature, then we form different patterns and shapes by the deformation. The preparation of fused glass takes place in an oven, at about 800-1000 Celsius degree, placed on a model, by melting. By changing the temperature and the heating times, we can influence how much the glass layers shall be fused into each other, this way unique and special shapes can be created. The technology of fusing is one of the most free glass processing technologies, as in addition to having the eternal variety of colors and patterns, the shape of the glass can be produced in countless variations. Fused glass cannot be tempered, it has decorative functions.
- minimal size: 150 mm x 300 mm
- maximal pane size: 2400 mm x 4500 mm
We can make the arched, laminated glasses in big size, adjusted to the laminating oven, up to 2700*5000 mm (arch height: up to 1000 mm). During the process, we bend separately each layer of the laminated glass structure to which we manufacture different bending models due to the different bending radius. The technology does not enable the bending of the already laminated glass layers because in this case the laminating foil would be burnt and the glass layers would fuse by melting. It is not possible either to bend several glass layers at the same time because the glass panes heated up almost to melting point would stick to each other, and this way it would not comply functionally with the concept of laminated glass, the look of the fractionally fused glass layers would not be aesthetic, moreover the formation of the stress hubs created this way would lead to the breaking of glass.
For lamination, another model is made where there is already no auxiliary structure. In case of bending, we must protect that side of the glass which contacts the model, so that is will not leave a trace of damage. When assembling the glass layers, it is suitable to apply 4 layers of EVA foil due to the eventual difference of the arches.
By applying enamel paint, we can create patterns, complete or partial transparency, colored design of the glass panes. During this technique, the painting spread on the surface is made resistant to mechanical and chemical impacts by burning during tempering. When creating the pattern, it is possible to apply silk-screening and roller painting, too.
During lamination, the surface of several layers of glass are “stuck” together, by which, according to its original purpose, multi-layer security glass is produced. This technique is also used for making load bearing glass surfaces, like glass beams, ceilings, step-proof, breakthrough-proof and anti-shoot glasses. Between these glass layers there is EVA type laminating foil. Between the foil layers, we can also place decorative layers, which offers an infinite range of possibilities. At the end of 2008, the laminating capacity of our company was increased with a new oven, so the maximal size of lamination: 2700*5000 mm.
We can assemble our heat insulation glasses in diverse sizes and shapes, from the simple angular enclosing shape to the arched or completely amorphous shapes. These structures can be realized even in case if the layers have different size. We often manufacture “skirted” heat insulation glasses when the exterior (or optionally any) layer is bigger, so it can cover the supporting structure needed for the integration. We can produce these glass structures not only from plane but also from arched glasses. In case of heat insulation glasses, it is not obligatory to temper or laminate the glasses, but for big size glass panes, it is recommended, and in this case, only the size of the tempering (2450*4500 mm) and laminating oven (2700*5000 mm) limits the feasibility. We equip our heat insulation glasses with one or two air gaps. The air gaps between the layers are made with spacer bars of different type and height, which can be made of aluminium: light grey, dark grey; or of plastic equipped with black hot edge, and of fireproof fiberglass bars. In case of the aluminium support bar, the size range starts from 5.5 mm and goes to 23.5 mm by 2 millimeters. In case of the plastic version, it starts from 10 mm and goes to 22 mm, also by 2 millimeters, for the fireproof fiberglass version, the available sizes are 12, 18, 22 and 28 mm. We can fill up the air gaps between the glasses with Argon gas for a better heat insulation effect. While in case of the one-layer, 6 mm Float glasses, the heat transmission coefficient (Ug) is 5.7, for two or three layers, having Low-E coated glasses between them, an Ug<1 value can be easily reached, too.
