What’s the Curved Tempered Glass and Hot Bending Glass Difference.

Bending Tempering Glass

Most commonly in the bending and tempering process, the glass is first heated to over 630 °C. Once heated, the glass is then bent to its target

radius in the bending station, its safety Tempered glass, Effectively improve the bending and impact resistance of glass, and the strength

is 4 times that of ordinary glass

FACT: Bent and tempered glass offers excellent mechanical strength and durability against temperature variations. The maximum bending angle is usually ¼ of a circle.

Hot Bending Glass

Hot-bend glass is a curved glass that is heated and softened in a mold by the flat glass and then annealed, it’s not the safety tempered glass.

In hot bending, the manufacturer uses molds, which allow the glass to adopt the desired form. The glass, as well as the mold, is then heated up to 580–600 °C.

Bending technology allows producers to create a wider range of shapes, for instance, a tighter radius and non-cylindrical shapes. The hot bending process itself does not add mechanical strength to the glass nor the ability to tolerate temperature variations.

Conclusion

1. Variety of product shapes: Hot-bent glass products have a variety of styles; curved tempered glass has a single style, which is only suitable for curved arcs with a radius of more than 500mm.

2. Product safety performance: hot-bent glass is unsafe glass; bent curved glass is safety glass.

3. Appearance quality: the surface of the hot-bent glass is smooth and there is no optical distortion; the bent tempered glass has wind spots and “broken shadows”.

4. Product reprocessing: hot-bent glass products can be processed by cutting, drilling holes, etc.; curved tempered glass has no secondary processing capability.
