Float glass has become the dominant category of flat glass globally, thanks to its efficient continuous production process. Its core production flow is simple and controllable, with standardized operations throughout from raw materials to finished products.
Core Four-Step Production Process
- Raw Material Preparation: Quartz sand, soda ash and other raw materials are mixed in proportion and melted into uniform glass liquid at high temperature (over 1500℃).
- Float Forming: The glass liquid flows into a tin bath, and naturally flattens and polishes at a constant temperature on the surface of the molten tin liquid to form a flat plate.
- Annealing and Cooling: The glass plate is slowly cooled to room temperature to eliminate internal stress and improve stability and strength.
- Cutting and Inspection: The cooled glass undergoes precise cutting and quality inspection to produce finished products of different specifications.
Outstanding Process Advantages
This process enables automated continuous production with a daily output of up to 1,000 tons. The product flatness is 30% higher than that of traditional processes. Through digital temperature control and tin bath sealing technology, energy consumption is reduced by 20%, which adapts to the needs of construction, automotive, electronics and other fields, and has become the core technical path for high-end glass production.
