Glass Laminating Machines

A Glass Laminating Machine is used in the glass fabrication industry for making laminated glass through the process of bonding two or more layers of glass with an interlayer, generally polyvinyl butyral or ethylene-vinyl acetate, or other material. This lamination process increases the natural safety, security, and performance characteristics of glass so that it can be used for any purpose.

How It Works

Preparation: Cleaning and preparing glass sheets and the selected interlayer material. Normally, the interlayer is cut to dimensions similar to those of the glass sheets.
Assembly: These glass sheets lie one on top of the other, with some interlayer material in between. This "glass sandwich" is then aligned and placed on a conveyor belt or in a laminating jig.
Pre-lamination: The assembly undergoes a pre-lamination process, usually rolling, for the eviction of air bubbles and probably to bond the interlayer with the glass surfaces.
Heating and Pressing: The assembled glass enter an autoclave—a large, pressurized oven. At high pressure, working with the heat, the autoclave will melt the interlayer, bonding it with the glass sheets. This process sucks out any remaining air pockets and forms a strong bond.
Cooling: After the cycle of heating and pressing, the laminated glass is gradually cooled, which makes it firmly adhere with the interlayer.

Applications

Laminated glass is used for windshields and helps in ensuring a reduced amount of injury in accidents.
Laminated glass is used to provide safety and security in windows, doors, façades, skylights, and balustrades.
Laminated glass performs decorative functions such as flooring, partitions, and railings with assurance of its aesthetic value and safety.
Used in many high-security places, including banks, jewelry shops, and government buildings for additional safety.
