  • Patent number: 11590683
    Abstract: A molding-forming method, a molding mold, and a molding production apparatus with which efficient burrs removal is possible without requiring a large apparatus. A molding production method includes, in addition to a molding being formed inside a mold, burrs formed around the molding are separated from the molding. After formation of the molding, air is blown inside the mold on at least a portion of the burrs formed around the molding to cool the same, a projecting member is projected toward the cooled burrs, and the burrs are separated from the molding. After pressing the burrs toward the projecting member by the air blowing, the burr is pressed toward the mold surface facing the projecting member by projection of the projecting member to separate the burr from the molding.

  • 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.
