Processes of the Glass Tempering Furnace

First Step

Based on customer and application requirements, a type of glass material is chosen. Fabricated annealed glass materials are fed to the Glass Tempering Furnace.

Second Step

After it has been sufficiently heated, the fabricated annealed glass materials roll out of the furnace and into a cooling chamber. Inside the cooling chamber, the glass is quenched/cooled down gradually. This is where tempered glass gets its strength. The dramatic temperature shock causes the surface and edges to become compressed, and the inner layer to be in tension. This process strengthens the material.

Last Step

Once the fabricated annealed glass materials roll out of the Glass Tempering Furnace, it is considered tempered glass. When a glass material is tempered, it breaks into smaller, duller pieces than annealed glass, making it the safer choice.
