Abstract: A forming apparatus for cleanly forming front glass for a portable terminal includes an upper mold 10 including an upper mold body 12 of a specific thickness and a protruded portion 14 protruded from the bottom surface of the upper mold body and a lower mold 20 including a lower mold body 22 of a specific thickness and a concave portion 24 concavely formed in the top surface of the lower mold body in such a way as to correspond to the protruded portion. Curved surface forming portions 16 and 26 are formed in the edge portion of the protruded portion 14 of the upper mold and the edge portion of the concave portion of the lower mold. The curved surface forming portions 16 and 26 are formed into line contact portions 16a and 26a coming into line contact with the end portions of the top and bottom surfaces of the glass, respectively.

Abstract: An apparatus for manufacturing front glass for an electronic device produced between an upper mold and a lower mold and having an at least partially curved surface, the apparatus including an inner tube 10 of a specific length and having an entrance portion for allowing the mold assembly for heat treatment to enter the inner tube and an exit portion for allowing the mold assembly after the heat treatment to exit; a conveyer belt for feeding a plurality of mold assemblies thereon, at specific speed in such a way as to pass through the inner tube; and a high temperature chamber 20 surrounding the inner tube between the entrance portion and exit portion of the inner tube and having a heat source for forming a high temperature atmosphere in order to form the front glass fed within the inner tube.
