Erecting a Float Glass Plant of Western Style Design

Glasstems  primary task is to provide unique services to each of our clients to fulfill their individual requirements. 

The most common services we supply are technology & engineering. These services usually include feasibility studies, budget estimates, overall plant design, project management, construction management , commissioning, list of process equipment, detail designs of melting furnace and tin bath, procurement of process equipment, site supervision, project operational procedure, float production technologies,  glass quality control, etc. 

With these services, clients are able to establish a western style plant of the state-of-art at minimum investment.  

The Float Process

At the heart of the worlds glass industry is the float glass process - invented by Sir Alastair Pilkington in 1952 - which manufactures clear, tinted and coated glass for buildings, and clear and tinted glass for vehicles. The process, originally able to make only 6mm thick glass, now makes it as thin as 0.4 mm and as thick as 25 mm.

Molten glass, at approximately 1000oC, is poured continuously from a furnace onto a shallow bath of molten tin. It floats on the tin, spreads out and forms a level surface. Thickness is controlled by the speed at which solidifying glass ribbon is drawn off from the bath. After annealing (controlled cooling) the glass emerges as a fire polished product with virtually parallel surfaces.

A float plant, which operates non-stop for between 10-15 years, melts raw materials mixture into glass from 100 tons to 1000 tons every 24 hours. Equipment investment may vary between USD15,000,000 to USD100,000,000 depending on the daily melting capacity.
