Glass is an ancient building material that has been around since ancient Egypt. With the common development of human society, the glass industry has created various kinds of glass with unique functions, making the glass family continue to thrive, such as bulletproof glass, photoelectric glass, vacuum glass, etc., all of which play an irreplaceable role in their respective fields, hot curved glass is also one of them.

Hot curved glass is heated and softened by float glass, then formed in a mold, and finally made by annealing. It has a beautiful style and smooth lines. It breaks the singleness of flat glass and is more flexible and diverse in use. It is suitable for fish tanks. Dining table. Balcony. Mobile phone counter, cosmetic counter, Hot curved TV cabinet, door, window, ceiling, curtain wall and other special requirements of different shapes. Can produce hollow, interlayer and other composite hot curved glass products, according to customer requirements Tailor made.

The hot curved glass is usually carried out in a hot curved furnace. First, cut the glass to the required size, then preheat, and heat the glass to near the softening temperature, and then the hot curved can be implemented. There are usually three methods for the hot curved: Compression bending method, gravity settling method and flexible bending method.

• Compression curved method

The male and female molds are made of steel according to the desired shape of the curved glass, and the outer surfaces are wrapped with glass cloth. The male and female molds are then pressed to press the thermoplastic glass. The glass is pressed and shaped according to the shape of the mold.

• Gravity Settlement method

Also known as the groove sinking method. In the heating furnace, the thermoplastic glass is bent under its own weight and falls on a mold of a certain shape. The equipment used in this method is simple, and the surrounding mold is used to bend the glass plate. The middle part of the glass will not be at all. There are mold marks, and its optical quality is often better than that of hard-faced pressed curved products.

The self-weight method can be used to produce curved glass with deep curvature around the edges and curved glass pairs for interlayer use. When the self-weight method is used, the glass may be deformed during the local heating process. Therefore, attention must be paid to make the heating amount of each part reach a good transition. state, strict requirements on the temperature curved and time during heating and curved.

• Flexible curved method

According to the curved surface required by the curved glass, the flexible roller is used to bend it into the required shape. In this hot curved equipment, the outer surface of the shaft center round steel is covered with a hose made of stainless steel. Install it at certain distances in the hose. A graphite wheel to support the outer hose. The rotation of the hose forms a flexible roller that makes the glass curved.
