An instrument panel () includes a base material portion () made of a base material Mand a different material portion () made of a different material Mhaving a different thermal shrinkage from that of the base material Mand in the instrument panel (), the base material portion () and the different material portion () are connected in a state such that at least a part of the two materials do not overlap.

Resin component, and molding method and molding device for same

An instrument panel unit () includes an instrument panel () and a decorative sheet (). The instrument panel () includes a sticking portion () and an exposed portion (). A plurality of insertion groovesand insertion holesare formed alternately at an end on a rear side of the sticking portion (), into which bent pieces () formed at a rear end of the decorative sheet () are inserted. A groove front-surface () forming the insertion groove () of the instrument panel () is formed in a tapered shape such that a width between the groove front-surface and an opposing groove rear-surface () gradually increases upwardly. The bent piece () is formed to be thinner than the groove width at the upper part serving as the entrance part of the insertion groove () and to be thicker than the groove width of a groove bottom-surface ().

Resin molded article unit and method for molding resin molded article unit

Provided are an injection mold and an injection molding method by which a boundary line between a first material and a second material curved so as to be sharply bent like a round chamfered shape can be formed reliably in a desired position, and a molded article molded using the injection mold and the injection molding method. The sum of a length w of an inclined-part forming partand a length y of a thinned-part forming partin a width direction of a linear part or a width direction of a curved part is at least equal to a prescribed value, and the thinned-part forming partforming the curved part has a second length y longer than a first length in the width direction of the curved part.

Injection mold, injection molding method, and molded article

An instrument panel () is formed by bonding a base material portion () composed of a base material Mand a different material portion () composed of a different material M. The different material portion () is infiltrated into the base material portion () and the infiltration portion () has a plurality of intermittent recessed portions.
