The Bürkle IFL process is a multi-stage laminating process, which uses a vacuum flat press heated on both sides in the first step. For glass thicker than average, a second step is recommended, which uses a flat press that also applies heat from above and below to the product. A flat press with cooled press plates is then used to cool the laminated glass. The system has a useful lamination area of 2,6m x 5,0m.

“This serial production system provides significantly faster turnaround time and reduced energy cost compared to conventional autoclave systems with unrivaled uniform glass laminate thickness. The system also uses a streamlined lamination process, which will further improve our process efficiency in laminating glass for our current product portfolio,” says Bruce Wesner, Sr. Director of Engineering Services, at PGT Innovations.

Bürkle’s in-line flat lamination system is ideally designed for production of laminated glass, safety glass (VSG), smart glass, decorative glass, solar modules, and other specialized glass products.

The Bürkle IFL process (IFL=Inline Flat Lamination) is distinguished by:

• Particularly fast lamination of laminated glass compared to autoclave processes (reduction of lamination costs)
• The possibility of line integration of the machines (inline process)
• Highest laminating quality due to particularly homogeneous heating plates heated on both sides
• The possibility of lamination with low pressures
• Much lower energy consumption compared to the autoclave process
