float glass

FLOAT GLASS is a distortion-free, virtually flat and transparent glass. It is manufactured by floating a ribbon of molten glass over a bath of molten tin. The ribbon is gradually cooled in an annealing lehr, washed and dried, and then cut into desired stock sizes.

performances and advantages

→ Possesses exceptionally smooth flatness.

→ Allowing distortion-free viewing and fine transmitted images.

→ Excellent light transmittance.

→ Creating a higher luminous interior.

→ The fire-polished surface giving a higher quality lustre and superb smoothness.

→ Most suitable for the silvering of mirror, producing fine reflected images.

Application

→ External use of windows, doors, shopfronts in offices, houses, shops, etc.

→ Interior glass screens, partitions, balustrades, etc.

→ Shop display windows, showcases, display shelves, etc.

→ Furniture, table-tops, picture frames, etc.

→ Ideal for silvering into mirrors, tempering into safety glasses, further processed for other industrial usage.

1. raw material

The production process begins with the careful selection of the raw materials - silica sand, soda ash, limestone, feldspar and dolomite. These matrials are placed in a batch house and then weighed and mixed according to very specific proportions. The mixed batch is conveyed to a furnace where it is heated at 1600 degress Celcius and become molten glass.

2. glass formation

The molten glass exits the furnace and is poured onto a bath of molten tin at a temperature of 800 degrees Celcius. Since molten tin has a higher specific gravity than glass, the molten glass spreads and floats on the tin surface producing a contiuous flat ribbon. The ribbon is pulled through the bath of molten tin and this process controls the thickness and the width produced. Upon exiting the bath, the glass ribbon enters the electrically heated annealing lehr where it is cooled in a tightly regulated manner. After cooling, the glass enters the cutting process.

3. cutting and quality control

To ensure the glass can be properly cut, the cooling process must be carefully regulated to release stress from the glass ribbon. After cooling, the ribbon passes through a washing process and undergoes a stringent quality check for defects. Random samples are also taken for a more detailed inspection of thickness, smoothness, optical distortion and transparency. Only after washing and inspection does the computer-controlled cutting machine cut the glass ribbon into the desired dimensions.

4. packing and distribution

After cutting to the desired size, the glass sheets are packed in a rack or a box, which is then marked with a bar code, and taken to the warehouse for storage, shipment and distribution.
