Abstract: A mobile terminal having a case defining an external appearance thereof, and a method of manufacturing such a case, are provided. The case may include a base formed of a resin material and having a recessed portion, a sheet disposed within the recessed portion and formed of a material that is different from that of the base, the material of the sheet having greater rigidity than that of the base, and a reinforcing member filled between the base and the sheet to integrally couple the base and the sheet. The rigidity of the material of the reinforcing member may have an intermediate value between the rigidity of the base and the rigidity of the sheet.

Abstract: A curved glass manufacturing method includes: successively stacking a lower mold, flat glass, and an upper mold, thereby forming a mold assembly; moving the mold assembly to a first chamber and then heating the same; moving the mold assembly from the first chamber to a second chamber and then pressurizing the upper mold so as to move the upper mold downward, thereby molding the flat glass in a curved shape; moving the mold assembly from the second chamber to a third chamber and then slowly cooling the molded glass; and moving the mold assembly from the third chamber to a fourth chamber and then cooling the molded glass. An elastic member is arranged between the lower mold and the upper mold and configured to define a space between the upper mold and the flat glass, and the elastic member is compressed when the upper mold is pressurized.
