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

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.

An injection molding apparatus includes an injector that obtains molten resin by melting resin, and injects the molten resin, a hot runner that is a flowing path of the molten resin, and a temperature rising part that is provided in a part of the hot runner, and increases a temperature of the molten resin to be higher than a melting temperature in the injector.
