  • Patent number: 11951676
    Abstract: A method for manufacturing a molding mold used in an injection molding apparatus includes: generating a first plasticized material by plasticizing a first shaping material containing an amorphous metal and a resin; and shaping a laminate that is a part of the molding mold by discharging the first plasticized material toward a stage to laminate a layer.

  • Publication number: 20230391010
    Abstract: A formed article producing method, includes a first step of shaping a shaping body by ejecting a shaping material including a thermoplastic resin and of forming a first formed article by cutting the shaping body with a first rotating tool; a second step of generating recycling material by cutting the first formed article with a second rotating tool; and a third step of forming a second formed article by ejecting the recycling material that was plasticized, wherein in the second step, the first formed article is cut under at least one condition of a condition that a moving speed of the second rotating tool is faster than a moving speed of the first rotating tool in the first step or a condition that a rotating speed of the second rotating tool is slower than a rotating speed of the first rotating tool in the first step.

  • Publication number: 20230382042
    Abstract: A method for manufacturing a molding die used with an injection molder, the method including plasticizing a creating material containing metal particles and resin to produce a plasticized material, and dispensing the plasticized material toward a stage to stack layers on each other to create a laminate that forms at least a portion of the molding die, with an average particle diameter D50 of the metal particles being smaller than or equal to 23 ?m.

  • Publication number: 20230339146
    Abstract: A mold manufacturing method used in an injection molding apparatus has a first step of shaping a laminated body that becomes a part of the mold by discharging molding material and stacking layers on a base plate having a first member with a first opening and a second member assembled into the first opening, a second step of removing the second member from the base plate on which at least a part of the laminated body has been shaped, and performing at least one of a cutting process and an insertion of a nesting member on the laminated body, which is at least partially shaped, and a third step, performed after the second step, of assembling the base plate with the laminated body is shaped, or a base plate with the laminated body is shaped and all the second members are removed, into the second opening in a mold base.

  • Publication number: 20230025852
    Abstract: A transparent liquid composition is provided which has excellent handling properties when used in cosmetic production without causing increases in viscosity or precipitation of insoluble matter during storage, and which imparts hydrophobicity to damaged hair when added to a cosmetic, and is smooth, moist and soft so feels good during use; a cosmetic containing this transparent liquid composition is also provided. This transparent liquid composition is characterized by containing (A) a compound selected from a group consisting of peptides, amino acids and derivatives thereof, (B) fatty acid amidoamines, (C) gluconic acid and/or gluconolactones and (D) a polyhydric alcohol, wherein the mass ratio (C)/(B) of component (C) to component (B) is 0.5-2.0.

  • Publication number: 20220339867
    Abstract: A three-dimensional shaping device includes: a plasticization unit that plasticizes at least a part of a material to produce a shaping material; a nozzle that ejects the shaping material to an uppermost layer; a moving mechanism that changes a relative position between the nozzle and the uppermost layer; a control unit that controls the moving mechanism such that the shaping material is ejected from the nozzle to the uppermost layer; and a compression unit that has a contact surface with a shape surrounding the nozzle and is capable of compressing the shaping material by bringing the contact surface into contact with the shaping material ejected to the uppermost layer.

  • Publication number: 20220234263
    Abstract: The injection molding apparatus includes a fixed mold, a movable mold facing the fixed mold, a mold clamping unit that moves the movable mold with respect to the fixed mold, and an injection unit that injects a molten material into a cavity defined by the fixed mold and the movable mold. At least one of the fixed mold and the movable mold is formed with a flow path communicating with the cavity, and a working fluid that pressurizes and pushes out a molded article in the cavity flows through the flow path.
