Technical requirements for hot bending glass

Hot bending glass can be classified into three categories based on its shape: single bending, bending, and composite bending.
For building glass with a single bend, hot bending of the glass is relatively easy. However, many manufacturers often find that the curved edges of their products, which are approximately 150mm away from the straight edge, cannot match the mold well, and some exceed the standard requirements, resulting in installation difficulties. To solve this problem, the first requirement is that the electric heating arrangement of the hot bending furnace should be reasonable, able to achieve local heating, and the placement direction of the product should be consistent with the direction of the electric heating wire.
The common bending hot bending glass includes aquarium glass and counter glass. The biggest technical difficulty of bending glass is the bending of straight edges and the easy occurrence of mold marks and other defects at the corners. Therefore, curved glass is also common, such as spherical glass, curved arched profiles, glass washbasins, etc. This type of glass requires a high level of technical proficiency in hot bending operations, precise mold making, and some require professional hot bending furnaces to complete.
