What is the ultra-clear curved glass panel?
A curved glass panel also referred to as bending glass, is glass that has been heated past its softening point and formed into a curved shape. Generally speaking, there are two types of curved glass panels: – hot bent glass and cold bending glass.
Hot bending glass is annealed for gravity bending. The glass panel is placed on or into a mold and heated up to glass softening temperature and then slowly cooled down after the exact shape is finished shaping. This method allows you to achieve many different shapes. But it is time-consuming and the production cost is high.
Cold bending glass is also called curved tempered glass, or curved toughened glass. It is processed in a tempered oven. After the desired shape is achieved in the curved mold in the tempering line, It will be cooled down rapidly to room temperature with the strong windjet. Cold bending glass (curved toughened glass) has 5 times higher strength than normal annealed glass.
Why use an ultra-clear curved glass panel for a glass jewelry display cabinet?
1. The ultra-clear curved glass panel has very strong light transmittance. Its perfect transparency assures you are able to obtain the perfect visual effect of natural color for your glass jewelry display cabinet.
2. The extra-clear curved glass panel offers a clear view without distortion of colors. It shows the true color of an object and enhances the aesthetics of the curved glass display cabinet.
3. Curved glass panels’ 360-degree visibility makes them ideal for a curved glass display cabinet for products to be viewed at all angles.

Production process details
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.
