Apparatus for manufacturing glass article and method for manufacturing glass article using the same

A method for manufacturing a glass article, the method comprising:

• providing a chamber defining an inner space that accommodates a single volume of a molten salt and a plurality of electrodes in contact with the molten salt;
• chemical strengthening surfaces of the glass article by immersing the glass article in the single volume of the molten salt disposed in the inner space of the chamber;
• and
• generating an electric field between the plurality of electrodes, wherein the electric field produces an asymmetrical effect on the chemical strengthening of the glass article, wherein an asymmetry of ions diffused into the surfaces of the glass article from the molten salt during the chemical strengthening simultaneously molds the glass article,
• wherein molding causes the glass article to change from a first planar shape to a second dome shape different from the first planar shape.

A method for manufacturing a glass article, the method comprising:

• immersing the glass article having a first surface, a second surface, and a sidewall connecting the first surface and the second surface in a molten salt disposed in an inner space of a chamber, wherein the first surface, the second surface, and the sidewall contact the molten salt, wherein the molten salt is provided as a single volume;
• and
• molding and chemical strengthening the first surface, the second surface, and the sidewall of the glass article at a same time by applying an electric field to the glass article,
• wherein a first electrode in contact with the molten salt is disposed in the inner space of the chamber,
• a second electrode in contact with the molten salt and facing the first electrode is disposed in the inner space of the chamber, and
• in the immersing the glass article, at least a portion of the glass article is disposed between the first electrode and the second electrode, and
• wherein in the molding and chemical strengthening the glass article at a same time, a chemical strengthened thickness of the first surface of the glass article facing the first electrode is greater than a chemical strengthened thickness of the second surface of the glass article facing the second electrode, and
• the glass article is bent toward the first electrode.
