What you need to know about hot bent glass
Jun 09, 2026
1.Definition
The bent glass is heated to softening point(around 600-700°C) under custom mold into curved shape by using gravity, ring molds or press bending.
2.Common methods
Gravity bending: glass form the shape under a mold by its own weight.
Press bending: glass pressed into shape between male / female molds.
3.Applications
Display cases, curtain walls, shower enclosures, automotive glass, elevator panels, furniture.
4.Limitations
The cost higher than flat or cold bent glass
Optical distortion possibly exist near edges
Limit size and radius due to furnace and mold design
After bending, the tempering is typical for safety glass requirements
5.Key inspection
Edge flatness, uniform radius, no waves or roller marks, proper annealing to avoid stress fractures.
