  • Publication number: 20210094092
    Abstract: A component part for an aluminum die-casting mold has an exposed surface that is a surface exposed to a cavity part of the aluminum die-casting mold and has diamond-like carbon coating formed at least on a part of the exposed surface, wherein the diamond-like carbon coating contains hydrogen in a content rate of 10 at % or more and 30 at % or less. The diamond-like carbon coating may further contain silicon in a content rate of less than 10 at %. Preferably, the content rate of silicon in the diamond-like carbon coating is 0.5 at % or more and 7 at % or less. Thereby, a component part for an aluminum die-casting mold which has excellent seizure resistance against molten metal containing aluminum can be provided.

  • Patent number: 10343312
    Abstract: An imprint device and an imprint method which form mold patterns on both surfaces of a molding target. An imprint device transfers mold patterns on both surfaces of a molding target using flexible first and second dies and includes first and second casings which each apply pressure of first and second pressurizing rooms respectively, to the first and second dies respectively and the molding target, a pressurizer that adjusts the pressures of the pressurizing rooms, first and second moving units that move the first and second dies respectively and the molding target in a direction coming close to or distant from each other, a depressurizer that depressurizes a depressurizing room formed between the first and second casings, and eliminates fluids present between the dies and the molding target, and a pressure adjuster that adjusts pressures to reduce pressure differences between the depressurizing room and the pressurizing rooms.

  • Patent number: 9751252
    Abstract: A shaping method and a shaping device are provided which can easily and inexpensively form a curved face in a film including a micropattern. A shaping method is for forming, in a predetermined shaping-target area of a film including a patterned face with a micropattern, and a rear face opposite to the patterned face, a curved face beyond the thickness of the film, and includes a fixing step for fixing an outer edge of the shaping-target area of the film by fixing means, a first heating step for heating the film 20 by heating means 95, and a pressure adjusting step for producing a predetermined pressure difference between both faces of the film by the pressurizing means in such a way that pressure at a side where the film is fixed in the fixing step becomes small to form a pre-curved face.
