Curving and Bending

The principle

Curved glass is produced in a horizontal mould by gently heating the glass to a temperature of about 620°C, just above its melting point. The glass slowly softens and takes the shape of the mould. The glass is then cooled gradually.

How do we produce curved/bent glass?

Step 1: Glass pane cutting  
The large-format glass (usually 4200 mm x 3210 mm) is cut to size, as per the work order. Glass dimensions vary with respect to parameters such as radius, depth, thickness, shape, etc.
Step 2: Processing  
All processing work, such as edge-working and drilling has to be carried out before bending the glass.
Step 3: Washing  
Each cut size pane is carefully cleaned under controlled conditions, to ensure that no impurities can affect the glass surface.
Step 4: Heating process  
Annealed glass, which have been cut to size, processed, edge-worked if necessary and washed, is heated, into a furnace, to a temperature of about 620°C, which is just above the softening temperature of glass. The glass will slowly soften and take the shape of the mould.
Step 5: Cooling process  
After the glass has taken the shape of the mould begins the cooling process: this cooling process is carried out very gradually in order to avoid internal stresses and too important deformations of the glass panes.
Step 6: Labelling, packaging and transport  
Labels, giving full information about the order, are affixed on the finished curved glass. The glass is usually placed on stillages, especially developed for glass handling and transportation. Transportation in wooden boxes is also possible.
