The overflow downdraw method or fusion method is a technique for producing flat glass. The key advantage of this technique as compared to the float glass process is the pristine surfaces, not touched by molten tin. The technique is used for the production of flat panel display glass by the companies Asahi Glass Co., Corning, Nippon Electric Glass,[1] Samsung Corning Precision Glass, and various other companies operating in the field of display glass and other types of thin glass.
The fusion method was originally conceived by Corning in the '60s as a method for manufacturing automotive windshields. Shelved for years, the technology was reintroduced to supply the flat screen display market.
