The present application belongs to the technical field of manufacture for protection film for a terminal curved surface, and relates to a protection film for a terminal curved surface and manufacture method thereof, the hardened layers is provided on both sides of the substrate layer, and the substrate layer and the two hardened layers form the original sheet. The original sheet is hot-pressed by a hot pressing device, and the upper mold and the lower mold clamping the original sheet are heated, pressurized and cooled in order to obtain a protection film for a terminal curved surface, and the mold core outer rounded corner combining with the mold cavity inner rounded corner are pressurized to form a curved surface portion. The hardened layers is disposed on both sides of the substrate layer, so that the stress on both sides of the substrate layer are cancel each other after the substrate layer is heated, and the terminal surface protective film is more flat. The protection film for a terminal curved surface is easy to be molded, sensitive to be touched, high in hardness, and the outer side hardness can reach 9H, which is not easy to produce scratches, anti-fingerprint, anti-fragmentation edge, explosion-proof, and the protection film for a terminal curved surface has a curved surface portion suitable for protecting the terminal curved screen.

The present disclosure relates to a method for manufacturing an optical element out of glass, wherein a blank made of glass is laid on an annular contact face of a supporting body having a hollow cross section, and is heated on the supporting body, in a cavity of a protective cap that is arranged in a furnace cavity, such that a temperature gradient is established in the blank in such a way that the blank is cooler inside than on an outside region, wherein the contact face is cooled by means of a cooling medium flowing through the supporting body, wherein following heating the glass blank is press molded to form the optical element.

Provided is a method of molding an optical element to obtain the molded optical element. The method includes: preparing a die set including an upper die having an upper molding surface, a lower die having a lower molding surface, a side die in which a through hole is formed, and a sleeve configured to accommodate the upper die, the lower die, and the side die; disposing a mold material on the lower molding surface after inserting the lower die into the through hole of the side die; heating the mold material; press molding the mold material with the upper die and the lower die to integrally move the side die and the lower die with respect to the upper die and the sleeve; and pushing the optical element upward by raising the lower die with respect to the side die and the sleeve.

A furnace (10) having a pressing punch (36), a pressure, distance and/or speed sensor and a control device for controlling a pressing process based on the output signal of the sensor. The sensor detects at least a pressure, position and/or motion parameter of the pressing punch (36). The pressing punch (36) acts on the bulk material of glass particles (32)possibly via an interposed ram (28), said glass particles being guided and crystallizable in a press channel (30). The trigger criterion for the process control is a change of at least a motion parameter of the pressing punch (36) upon softening of the bulk material of glass particles (32) which change is detected by the sensor.

The disclosure relates to a method for manufacturing an optical element, where a blank of glass is heated and/or provided and, after heating and/or after being provided between a first mold (UF) and at least one second mold (OF), is press molded, for example on both sides, to form the optical element and is then sprayed with a surface treatment agent.

The current disclosure relates to highly homogeneous glass sputter targets with a large aspect ratio and a high relative density. The glass sputter targets have properties that are desirable for forming thin films by physical vapor deposition processes such as sputtering.

A glass manufacturing apparatus configured to manufacture glass through a process of lowering the temperature of a non-contact supported glass material. The glass manufacturing apparatus comprises a heating unit configured to heat the glass material; and a forming unit configured to form the molten glass material while its temperature decreases after the heating by the heating unit has stopped.

The present invention provides an infrared-transmitting glass that is a chalcogenide glass, has a reduced Ge content, can sufficiently cover atmospheric windows, is free from highly toxic elements, such as Se and As, and is suitable for mold forming. Specifically, the present invention provides an infrared-transmitting glass suitable for mold forming, comprising, in terms of molar concentration: 0 to 2% of Ge, 3 to 30% of Ga, 10 to 40% of Sb, 45 to 70% of S, 3 to 30% of at least one member selected from the group consisting of Sn, Ag, Cu, Te, and Cs, and 0 to 30% of at least one member selected from the group consisting of Cl, Br, and I.

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.
