In our daily work we use high-quality and durable German and Austrian glass processing equipment, which we constantly update to provide our customers with the best possible solution from standard jobs to complex special shapes. Our processing options include glass cutting, edging, processing openings and special shapes, drilling openings, glass tempering and lamination.
The treatment process of flat glass starts with cutting. W-Glass has a fully automatic ESL-RS cutting line and a combination Lisec Fit.Cut+VB33 line from LISEC for cutting float and laminated glass.
We cut flat glass with a thickness of 4 mm to 19 mm with a maximum size of 3,210 x 6,000 mm
Edging
Edging of the glass is done depending on the purpose and need. We edge glass with a thickness of 4-19 mm. Edges of the glass and mirror can be treated by means of simple technical grinding or phase and bevel grinding.
For technical grinding of glass (except for performing special shapes), we use the Lisec KSR-25 grinding line, which allows processing glass with maximum dimensions of 2,500 x 5,000 mm.
To make phase grinding on the edges, we use a Benteler TecGrinder modern and fully automatic double edge grinding line, which allows the two parallel sides of the glass to be ground simultaneously. Benteler TecGrinder allows you to process glass with a maximum size of 2,300 x 4,800 mm.
We use a Bimatech Pratica GLP CNC bench for processing straight-surfaced flat glass with openings and special shapes. Bimatech Pratica allows drilling regular large openings, glass milling as well as special-shaped edge treatment of glass with sizes up to 1,400 x 3,000 mm.
Openings and cuts
For drilling and making cuts we use the Forvet Francesca FC 16M 1250 and Lisec Topdrill M-RX 200 drilling/milling bench, of which the first permits to treat glass with a thickness of 4-12 mm and the latter with a thickness of 4-19 mm. The Forvet drill bench permits treating glass with a maximum size of 2,000 mm x 3,600 mm and the Topdrill bench with a maximum size of 2,000 mm x 4,800 mm.
Bevel
We offer bevelling for almost all types of glass with a thickness of 4-12 mm, whereas the minimum size is 150 mm x 150 mm and the maximum size is 2,000 mm x 2,500 mm. For glass ordered from, us we can offer bevelling with a width of 10-28 mm. For this we use the Bevel Var7 bench from the Italian company Zafferani.
Glass tempering
During the glass tempering process, glass is subjected to thermal treatment by heating it in a special tempering furnace to a melting point (approx. 700 degrees depending on the thickness of the glass) and then cooling it rapidly. The process preserves the reflection and expansion properties of the glass, but the structure and durability of the glass change a bit. The change in the structure is characterised by the fact that in the event the tempered glass breaks, then compared to the untreated glass, it breaks into many small pieces, the edges of which are usually blunt. Regarding durability, tempered glass is up to five times stronger than regular glass of the same thickness, but it should be borne in mind that tempered glass is not stronger at the edges and that this type of glass is particularly weak in the corners.
Thermally tempered glass can no longer be cut, drilled or ground after tempering. Therefore, all treatments must be carried out before tempering.
W-Glass has the TAMGLASS HTF tempering line from the leading manufacturer of flat glass tempering furnaces in the world, which allows us to temper glass sheets at a minimum size of 280 mm x 100 mm and a maximum size of 2,400 mm x 4,800 mm.
Lamination
Lamination means combining two or more sheets of glass with a special film. For lamination, we use PVB, Sound Control PVB and EVA film.
W-Glass uses the LISEC IAS automatic lamination line to laminate sheets of glass, which allows the production of multiple laminates with minimum dimensions of 200 mm x 400 mm and maximum dimensions of up to 2,600 mm x 5,100 mm.
