The bending principle of a flat bending tempering furnace involves heating and shaping glass sheets into curved or bent forms. This process, widely used in manufacturing applications such as automotive and architectural glass, uses controlled heating, bending, and tempering to achieve the desired shape and mechanical properties.
Bending principle of flat bending tempering furnace
1. Heating Phase
The flat glass sheet is placed on rollers and enters the furnace, where it is gradually heated to the softening point (typically around 600-700°C, depending on the glass type).
The heating is carefully controlled to ensure uniform temperature distribution across the glass. Uneven heating can cause distortions or weak points.
2. Bending Process
Once the glass reaches the target temperature and becomes pliable, it is moved to a bending station where the actual shaping occurs. There are two main bending methods in flat tempering furnaces:
