    摘要: A lens forming method is provided, including: heating a blank mold with a pre-molding cavity until a glass preform in the pre-molding cavity is in a semi-molten state; applying a pressure to the blank mold, so that the glass preform is extruded to form a lens rough blank with a predetermined shape; cooling the blank mold and the lens rough blank, and separating the blank mold by depressurization, to transfer the lens rough blank to a molding cavity of a high-precision aspherical mold; heating the high-precision aspherical mold until the lens rough blank is softened to a semi-molten state; applying a pressure to the high-precision aspherical mold, so that the lens rough blank is extruded to form a lens molded part with an aspherical structure; and cooling the high-precision aspherical mold and the lens molded part, and separating the high-precision aspherical mold by depressurization, to remove the lens molded part.

    摘要: A parallelepipedal low-pressure plasma chamber body of glass is disclosed. The low-pressure plasma chamber may have electrodes at opposing sides of the low-pressure plasma chamber body. Furthermore, the low-pressure plasma chamber may have at opposing sides a door and a rear wall closure. The door and rear wall closure may in each case have at least one media connection in order to achieve a uniform gas flow in the low-pressure plasma chamber. The door may be assembled on the collar of the low-pressure plasma chamber body which extends radially away from the longitudinal axis of the low-pressure plasma chamber body. The low-pressure plasma chamber body is preferably produced using the pressing method or blow-and-blow method, in an analogous manner to industrial glass bottle production.

    摘要: The method for manufacturing a plate glass is a method for manufacturing the plate glass having sides of at least 30 cm or more and a surface thereof on which a predetermined shape is formed. In the manufacturing method, the flat plate glass is heated to a temperature which is lower than a softening point and at which the heated flat plate glass is deformable by being pressed at a predetermined pressure or higher, the heated flat glass, which has been molded by pressing the flat plate glass with a die having a die structure for forming the predetermined shape, is cooled to the strain point while being held with the die. Further, in the manufacturing method, the pressing is performed with the die having a coefficient of thermal expansion whose difference from that of the plate glass is 2.0×10−6/K or less.

    摘要: A cover window manufacturing apparatus includes a plurality of fixed plates, a plurality of moving plates, a plurality of molds and a driver. The plurality of fixed plates is layered and spaced apart at a distance from each other. The plurality of moving plates is layered, spaced apart at a distance from each other and respectively disposed under the plurality of fixed plates. A plurality of connection members integrally connects the plurality of moving plates with each other. The plurality of molds is respectively provided on the plurality of moving plates, and inner spaces for molding the cover window are respectively defined in the plurality of molds. The driver is coupled to one of the plurality of moving plates, and is configured to move the plurality of moving plates towards the plurality of fixed plates such that the plurality of molds are pressed to the plurality of fixed plates.
