Corning’s Proprietary Fusion Process Explained

Corning has done just that with its proprietary fusion draw process.In this process, engineers utilize advanced,highly automated technology to form the glass in the air and draw it down to form an incredibly thin, flat piece of glass.

So, just how does the fusion draw process work? Envision a trough being filled with water. Once the water fills the entire trough, the excess water has no choice but to flow over and down the sides. Once this occurs, the water meets at the base of the trough, forms a plane and flows down creating an uninterrupted sheet. This in essence, is how the fusion draw process works.

This precise process produces glass covers and substrates with exceptionally clean, smooth, flat surfaces, that have inherent dimensional stability – qualities essential to successfully manufacture today’s cutting edge displays.

Because Corning^® Gorilla^® Glass is formed using this process, it requires no subsequent surface grinding or polishing, which helps minimize flaws and drastically reduces both time and cost.



To maintain quality from start to finish, Corning has mechanized the handling processes. No matter how large next-generation glass becomes, Corning will continue to focus on the technology behind the glass and stay ahead of what’s next in advanced display technology.
