Abstract
An instrument panel (10) includes a base material portion (20) made of a base material M1 and a different material portion (30) made of a different material M2 having a different thermal shrinkage from that of the base material M1, and in the instrument panel (10), the base material portion (20) and the different material portion (30) are connected in a state such that at least a part of the two materials do not overlap.
Claims5
A resin component comprising:
- a first resin portion composed of a first resin material;
- and
- a second resin portion composed of a second resin material having a different thermal shrinkage from a thermal shrinkage of the first resin material, the first resin portion and the second resin portion being connected in a state of at least partially not overlapping,
- the resin component further comprising:
- a discontinuous portion at a portion inward of a boundary location of the second resin portion with the first resin portion,
- wherein the discontinuous portion is a cut having a V shape when seen from above, and a connecting point of two sides of a V shape of another through hole or bottomed hole is positioned within an area defined by three sides connecting three end points of the V shape.
A method for molding a resin component in which a first resin portion composed of a first resin material and a second resin portion composed of a second resin material having a different thermal shrinkage from a thermal shrinkage of the first resin material are connected in a state of at least partially not overlapping, the resin component further comprising a discontinuous portion at a portion inward of a boundary location of the second resin portion with the first resin portion, wherein the discontinuous portion is a cut having a V shape when seen from above, and a connecting point of two sides of a V shape of another through hole or bottomed hole is positioned within an area defined by three sides connecting three end points of the V shape,
- the method comprising:
- supplying the first resin material into a portion of a cavity configured to mold the first resin portion of the molded resin component;
- and
- supplying the second resin material into a portion of the cavity configured to mold the second resin portion of the molded resin component, the cavity comprising a V-shaped projection disposed at a portion closer to the second resin portion than a boundary location between the first resin portion and the second resin portion of the molded resin component, to form the cut having the V shape.
