Abstract:
A process using a three-piece mold for making a three-dimensionally shaped glass article having a flat area and a curved/bend area is disclosed. The process includes placing a glass sheet on a mold having a shaping surface with a desired surface profile for the shaped glass article including a flat area and a bend area, moving a flat area plunger toward the glass sheet to compress the glass sheet, heating a portion of the glass sheet corresponding to an area above the bend area of the mold to a temperature above a forming temperature, and moving a bend area plunger toward the heated glass sheet to compress the heated glass sheet. A temperature of the glass sheet in the area above the bend area of the mold is higher than a temperature of the glass sheet in the area above the flat area of the mold when compressing the heated glass sheet with the bend area plunger.
