Production of laminated safety glass

Production of laminated safety glass

After cleaning the glass surfaces, the glass sheets and PVB films are laid on top of each other, heated and compressed by rollers or vacuum to form a pre-bond. The elements then enter the autoclaves, where they are permanently bonded together under pressure and heat. Edge processing follows the manufacturing process. If ESG or TVG is processed to laminated safety glass, no edge processing can be carried out subsequently.

Production of laminated safety (LSG) - Scheme

1. Charging

The system is fed by gantry stackers.

2. Cleaning

The glasses are cleaned in the washing machine. The glass thickness is measured automatically, after which the machine parameters are set automatically.

3. Laminating room

In this room, glass-foil-glass are assembled using the sandwich principle. Since the PVB film is very sensitive to temperature and humidity and each grain of dust causes an impairment of the optical quality, the laminating room is an air-conditioned clean room. For this reason, the films are also stored in air-conditioned rooms for specific products.

4. Pre-bond

In the pre-composite furnace, the so-called pre-composite is produced from the glass plates and the film between them. For this purpose, the glass plates are heated in a defined manner and pressed together by means of rollers.

5. Autoclave

In the autoclave, the glass sheets are permanently bonded to the film under pressure and temperature. The finished laminated safety glass panel is thus created from the pre-composite.

6 Unloading/Delivery

After autoclaving, further processing such as grinding or drilling on the glass can be carried out.
