Publication number: 20200016869Abstract: 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.Type: ApplicationFiled: September 24, 2019Publication date: January 16, 2020Inventors: Marianne Griesback Park, John Richard Ridge, Ljerka Ukrainczyk

Publication number: 20190367402Abstract: A method for compensating for warp in a glass article including placing the glass article on a fixture, heating the glass article to a first temperature in a viscoelastic range, cooling the glass article on the fixture to a second temperature, and then removing the glass article from the fixture and cooling the glass article to room temperature. The fixture may include a recess such that when the glass article is heated to the first temperature, the glass article sags into the recess. The fixture may be a flat plate when the glass article is heated to the first temperature, a temperature gradient is formed within the glass article. A method for compensating for warp includes physically removing portions of the glass article that are determined to warp when chemically strengthened.Type: ApplicationFiled: May 29, 2019Publication date: December 5, 2019Inventors: Rohit Rai, John Richard Ridge

Patent number: 9975800Abstract: A glass sheet is formed on a mold into a glass article having a three-dimensional shape. The mold, with the glass article thereon, is arranged within an interior space of a radiation shield such that the mold is between a leading end barrier and a trailing end barrier of the radiation shield. The mold, glass article, and radiation shield are translated through a sequence of cooling stations while maintaining the mold between the leading and trailing end barriers, wherein the leading and trailing end barriers inhibit radiation heat transfer at leading and trailing ends of the mold.Type: GrantFiled: August 18, 2016Date of Patent: May 22, 2018Assignee: CORNING INCORPORATEDInventors: Thierry Luc Alain Dannoux, Raymond Chih Chung Hsiao, Nikolaos Pantelis Kladias, Rohit Rai, John Richard Ridge, John Robert Saltzer, Jr., Ljerka Ukrainczyk

Publication number: 20180134614Abstract: A process for forming a textured 3-D glass-based substrate includes texturing a first surface of a glass-based substrate and shaping the glass-based substrate into a three-dimensional shape. The surface profile of the substrate is non-planar. In some embodiments, texturing the first surface of the glass-based substrate provides the first surface with an average roughness of 10 nm to 2000 nm.Type: ApplicationFiled: November 15, 2017Publication date: May 17, 2018Inventors: Jill Marie Hall, Yuhui Jin, Timothy James Kiczenski, John Richard Ridge, Ljerka Ukrainczyk

Patent number: 9779190Abstract: Methods for compensating for the warp exhibited by three-dimensional glass covers as a result of ion exchange strengthening are provided. The methods use a computer-implemented model to predict/estimate changes to a target three-dimensional shape for the 3D glass cover as a result of ion exchange strengthening. The model includes the effects of ion exchange through the edge of the 3D glass cover. In an embodiment, the inverse of the predicted/estimated changes is used to produce a compensated (corrected) mold which produces as-molded parts which when subjected to ion exchange strengthening have shapes closer to the target shape than they would have had if the mold had not been compensated (corrected).Type: GrantFiled: February 11, 2016Date of Patent: October 3, 2017Assignee: Corning IncorporatedInventors: Izhar Zahoor Ahmed, Keith Raymond Gaylo, Jacob Immerman, John Richard Ridge, John Robert Saltzer, Jr., Ljerka Ukrainczyk
