Glass Processing

Thermal Tempering

In the thermal tempering process, the bottom and top surfaces of the glass are heated in a furnace.

Capability
Thickness
3.2mm – 10mm
Size
20mm*20mm – 2000mm*1000mm
Compared to float glass
4-5 times stronger
Coated glass
Can be tempered

Recommended temperatures vary, but the glass reaches temperatures of 600°C - 700°C. The hot glass suddenly exits the furnace and is then rapidly cooled by a high air flow for a period of 10 to 30 seconds. As a result, the surfaces shrink; tensile stresses first form on the edges and then progress towards the center of the glass until the whole surface is stressed.

Advantages of Thermal Tempering

  • It breaks into small pieces when broken, so it is used as safety glass
  • It is considered 4-5 times stronger than float glass
  • It has higher heat resistance than float glass
