  • Fiber-reinforced resin intermediate material, fiber-reinforced resin molded article, and method for producing fiber-reinforced resin intermediate material
    Patent number: 11065829
    Abstract: The fiber-reinforced resin intermediate material according to the present invention is formed by attaching a resin powder to an outer surface of a reinforcing fiber substrate formed of reinforcing fibers and heating it to melt the resin powder to the outer surface of the reinforcing fiber substrate so as to have an uneven shape derived from the resin powder and also have an opened void space.
    Type: Grant
    Filed: April 14, 2017
    Date of Patent: July 20, 2021
    Assignee: THE JAPAN STEEL WORKS, LTD.
    Inventors: Akio Ono, Hiroshi Ito, Tsukasa Shiroganeya, Takuya Niyama, Takuya Iwamoto, Shigeki Inoue

  • Method of controlling holding pressure in injection molding and apparatus therefor
    Patent number: 5296174
    Abstract: A method of controlling holding pressure in an injection molding operation and an apparatus therefor, wherein the quality of molded products can be controlled with a high accuracy without the need for a pressure sensor in a mold and without requiring any additional data such as the thickness of a molded product, the effective heat diffusion rate, and so on. Further, a method for estimating resin temperature in injection molding and an appartus therefor, wherein in-mold resin temperature in a holding pressure and cooling stage is estimated during injection at a high speed and with a high accuracy.
