Hot Bending Glass process for Unbelievable Architectural Curved Glass

What’s great about today’s technology is that it allows us to push the known limits into exciting, unknown territory. The hot bending glass technology is innovative, allowing for studying and creating truly life-changing designs. This is what we are starting to see in the form of curves and shapes in the field of glass architecture. And as the latest architectural design trends suggest, the world is ready for curved glass.

Cutting and Edging

When float glass comes off the manufacturing line it is a flat sheet. Large sheets of glass are scored into a range of end-use sizes. After that, these individual pieces of glass are edged on a vertical line and sent to an industrial washer.

Curved glass mold

The hot bending process usually begins with steel pieces. That forms a mold as a baseline for the glass that they will bend into the desired shape. Once the mold is completed, it’s preheated to the desired temperature for about an hour before the glass is put into the mold. Any great temperature disparities between the mold and the glass could cause the glass to shatter, so preheating the mold is very important.

After the mold is preheated and removed from the kiln, the glass is placed on top of it, and the whole thing is loaded back into the kiln. Once the kiln reaches the desired temperature – about 700 degrees C – the molecules in the glass begin to speed up and it begins to melt and bend, bending can be solely based on gravity. Alternatively, the glass bending process can be assisted in which a mechanical bending press forces the glass into a target shape. The shape is then slowly cooled to avoid any residual tension in the glass, completing the hot bending glass

Hot Bending Glass VS Curved Tempered Glass

1. Glass bending process:

  • The hot bending process is cooled in nature after heating up and does not add mechanical strength to the bent glass nor the ability to tolerate temperature variations.
  • The curved tempered glass bending process is cooled rapidly after heating up, making excellent mechanical strength and durability against temperature variations to bent glass.

2.  Variety of product shapes:

  • Hot Bending 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 900mm.

3. Product safety performance:

  • Hot bending glass is unsafe glass, we can laminate it and make it safety glass.
  • Curved tempered glass is safety glass.

4. Product reprocessing:

  • After the hot bending process, bent glass products can be processed by cutting, drilling holes, etc.
  • Curved tempered glass has no secondary processing capability.

Packing and Delivery

There are thick foam pads to prevent the glass from banging around inside the case:
