  • Publication number: 20210180377
    Abstract: A structure body having a resin molded body which can suppress deterioration of external appearance due to meander of the folded line formed in the hinge portion even when the resin constituting the resin molded body contains an inorganic fiber. The structure body has a resin molded body and the resin molded body includes: a first main body portion and a second main body portion; and a hinge portion; wherein the first main body portion and the second main body portion are connected at the hinge portion with each other so as to be rotatable with respect to each other; the hinge portion comprises a first thin portion, a second thin portion, and a thick portion.

  • Patent number: 9174402
    Abstract: A mold for manufacturing a climate control duct, which has a protrusion formed on an outer peripheral surface thereof and is formed from a foamed resin, includes a groove provided on at least a part of a surface of the mold for transfer of a shape of the protrusion. The groove of the mold satisfies a relation D<W<4×D, in which W represents a width of the groove and D represents a depth of the groove.

  • Patent number: 8770232
    Abstract: The invention provides a method for manufacturing a climate control duct, the method capable of improving a characteristic of transferring a shape of a protrusion onto a surface of a duct and capable of preventing reduction in ventilation efficiency. In order to manufacture a climate control duct having a protrusion formed on an outer peripheral surface thereof, the method includes subjecting an extruded foamed resin to blow molding by use of a duct-shaped mold in which a groove for transfer of a shape of the protrusion is formed on at least part of a surface thereof. Herein, the following relations are satisfied: 0.5 mm<D<5 mm, D<W<4×D, and W<2×T, in which W represents a width of the groove, D represents a depth of the groove, and T represents a thickness of the foamed resin.
