METHODS OF FORMING SHAPED GLASS ARTICLES FROM GLASS SHEETS

A method of forming a 3D glass article from a glass sheet includes locating the glass sheet on a mold assembly including a mold surface with a 3D surface profile corresponding to that of the 3D glass article. The glass sheet is heated to a forming temperature. The forming temperature is greater than...

Summary:A method of forming a 3D glass article from a glass sheet includes locating the glass sheet on a mold assembly including a mold surface with a 3D surface profile corresponding to that of the 3D glass article. The glass sheet is heated to a forming temperature. The forming temperature is greater than a temperature of the mold surface. The heated glass sheet is forced onto the mold surface by applying a pressurized gas to a first surface of the glass sheet opposite the mold surface to conform the glass sheet to the mold surface with the glass sheet at the forming temperature that is greater than the temperature of the mold surface.
