Glass Tempering
for Added Safety, Strength & Durability
We supply heat strengthens, heat tempers and chemically strengthens glass for OEM customers around the world!
Safest Production Standards For Highest Assurance
After your glass is cut and shaped to your specifications, it is inspected, washed, and placed within our in-house tempering ovens, which boast industry-standard temperatures of more than 600 degrees Celsius (1,112 degrees Fahrenheit). The heated glass then undergoes high-pressure cold air blasts, causing the outer layers to cool and contract faster than the interior, creating tension between the layers. As this pressure increases, the glass becomes stronger and less likely to break.
Heat Tempered Glass
It’s also referred to as safety glass, is used in the toughest applications requiring high impact strength, resistance to thermal stress and a safety break pattern.
- Surface of glass in compression > 10,000psi
- 4-5x times more impact resistant than annealed glass
- Withstands some bending and rapid temperature change
- Available in thicknesses ranging from 1/8” (3mm) to ¾” (19mm)
Heat Strengthened Glass
It’s specified for applications where fully heat tempering the glass may not be an option due to the thickness of the glass or type of glass. Heat strengthened glass typically yields a slightly better cosmetic surface than fully heat tempered glass but will not break into a full safety dice pattern.
- Surface of glass in compression between 3500-7000psi per ASTM C 1048
- 2-3x times more impact resistant than annealed glass
- Available in thicknesses ranging from .090” (2mm) to ¾” (19mm)
Chemically Strengthened Glass
It’s typically used for thinner glass applications or applications requiring pristine surface quality such as an electronic displays or cover glass. Our chemically strengthens sodalime glass, non-glare glass and also high-ion exchange materials such as Corning Gorilla Glass.
- Glass is toughened through a sodium and potassium ion exchange in salt bath
- Typical glass strengthening cycles are 8 hours or 16 hours
- Modulus of Rupture: 8 hours 165MPa / 16 hours 220MPa
- Added bending ability and has added scratch resistance
- 5-6x more impact resistance than regular un-strengthened glass
- Available in thickness range from .008 (.210mm) to ¾” (19mm)
