Tempering Process at Thermotec Glass
The glass tempering process involves controlled heating and rapid cooling to enhance the strength and durability of the glass. Here’s a step-by-step breakdown of how our tempering furnace operates:
Loading Glass
Raw glass sheets are carefully placed onto the conveyor system of the tempering furnace. The glass is positioned for even heating, ensuring optimal results.
Heating Stage
The furnace uses radiation and convection heating to gradually raise the glass temperature to approximately 600–700°C (1,100–1,300°F)—the softening point of glass. Uniform temperature distribution is achieved using advanced heating control systems, reducing defects such as optical distortion or uneven stress.
High Pressure Quenching
Once heated, the glass rapidly moves into a high-pressure air quenching section. Powerful air jets cool the glass uniformly and quickly, locking in surface compression while keeping the interior in tension. This controlled cooling process increases glass strength by 4–5 times compared to standard annealed glass.
Quality Inspection
The tempered glass is inspected for flatness, surface quality, and optical clarity. Any defects, such as bending irregularities or surface imperfections, are minimized using precision control systems.
Final Delivery
The tempered glass is carefully packaged and prepared for architectural, automotive, interior design, or industrial applications.
