A duct structure having excellent sealing performance at a connection portion between a duct and a piping member. The duct structure includes a duct and a piping member. The duct includes an opening in a tubular portion, and the piping member includes a piping portion. The piping portion is inserted into the opening and connected to the duct, and a foam rubber sealing material is disposed in a compressed state between an outer peripheral surface of the piping portion and an edge of the opening.

Duct structure

A mold which can improve an appearance of a molded body is provided. A mold includes a cavity, the mold being capable of subjecting a resin sheet under reduced pressure suction via a plurality of reduced pressure suction holes thereby shaping the resin sheet to follow a shape of an inner surface of the cavity; wherein: the inner surface includes a base surface and a plurality of island-like concave portions provided in the base surface; and a concave portion reduced pressure suction hole index defined by an in-concave reduced pressure suction hole ratio divided by a concave portion area ratio is 0.5 or lower.

Die, manufacturing method therefor, and molded body manufacturing method

The first aspect of the present invention provides a foamed structure, comprising: a first foamed body extending in a first direction; a second foamed body extending in the first direction and facing the first foamed body with a gap interposed therebetween; and a reinforcement disposed in the gap between the first foamed body and the second foamed body, the reinforcement having an elongated shape, wherein the first foamed body has a portion overlapping with the second foamed body in the first direction view.

Disclosed is a hollow molded article which has an opening portion communicating with a flow channel and which can be manufactured simply. The hollow molded article includes a panel and flow channels. The panel includes a first resin sheet and a second resin sheet partly welded with the first resin sheet. The flow channels are disposed between the first resin sheet and the second resin sheet, and include connection portions for external connection which are disposed on a peripheral edge of the panel. The connection portions are formed by the first resin sheet and the second resin sheet.

Hollow molded article

A resin panel according to an embodiment includes a core material, a reinforcing material, a skin material covering the core material and the reinforcing material, and a fastened member. A reinforcing material has a first plate provided on a front surface of the core material, a second plate provided on a back surface of the core material, and a connecting plate connecting the first plate and the second plate. The fastened member is attached to the skin material by a fastening member penetrating the skin material and the first plate or the second plate of the reinforcing material.

Foamed structure and resin panel

A container of a puncture repair agent includes: a bottomed cylindrical container body to store the puncture repair agent; and a mouth portion provided on the container body, from which the puncture repair agent is pushed out by pressing the container body, wherein the container body is hollow molded into a flat shape and includes a barrel portion, wherein the barrel portion includes a pair of narrow portions facing in a major axis direction, and a pair of wide portions facing in a minor axis direction, and wherein each of the pair of wide portions is provided with a pressing recessed portion capable of being recessed in a concave curved surface shape toward inside of the barrel portion.

Container of puncture repair agent

A method of producing a vehicle interior panel having a hollow double-walled structure made of thermoplastic comprising, blow molding with a pair of mold halves including a first mold with a shape transfer surface having a three dimensional pattern, and a second mold, clamping a cover material being formed by at least a double-layer structure arranged between a cavity of said first mold and a parison of thermoplastic such that a resin sheet layer without a through hole and without a three dimensional pattern faces a cavity of said first mold, introducing a pressurized fluid into the parison to press the cover material and the parison against a cavity surface, thereby integrally laminating said cover material to an outer surface of a first wall of the panel having the hollow double-walled structure and transferring said three dimensional pattern of said first mold half to said resin sheet.
