First, how is the curved glass made?
The glass is pre-processed (cut to the desired size) and then heated to a softening temperature, and then by its own weight or external force, the glass becomes a non-planar shape that matches the mold in various specific molds, and then Annealing process to make the required curved glass, can make hot bending, hot bending, hot bending and other composite products.
Bending tempered glass or curved heat reinforced glass is made by bending the glass and then rapidly air-cooled by special equipment.
Second, the technical requirements of hot bending glass
Hot-bending glass is classified into three categories: single bend, bend, and composite bend.
For a single curved architectural glass, glass bending is relatively easy. However, many manufacturers often have a curve edge of approximately 150 mm from the straight side of the product, which cannot be well matched with the mold, and some of them exceed the standard requirements, resulting in difficulty in installation. To solve this problem, it is first required that the electric heating arrangement of the hot bending furnace should be reasonable, and local heating can be realized, and the direction in which the product is placed should be consistent with the direction of the heating wire.
Commonly used in bending hot-bending glass are aquarium glass and counter glass. The main technical difficulties of bending glass are the bending of straight lines and the appearance of mold marks at the corners. Therefore, curved glass is also very common, such as spherical glass, curved arched profiles, glass wash basins, etc. This type of glass requires a high level of skill in hot bending operations, making precise molds, and some require professional heat. The curved furnace can be completed.
