Abstract: A method for producing a metal-resin composite includes a coating step, an assembling step, and a heating step. The coating step coats at least part of the outer periphery of a solid metal first member with a foaming resin and a non-foaming resin. The assembling step disposes the first member within a hollow metal second member. The heating step heats an assembly of the second member within which the first member coated with the foaming resin and the non-foaming resin with the axes of the first member and the second member extending in the horizontal direction, and thus foams the foaming resin between the first member and the second member.

Abstract: Provided is a lightweight heat ray shield cover, such as a heat insulator, which has a three-dimensional shape and excellent shielding characteristics. The heat ray shield cover is a cover which is disposed near a heat source (26) such as an engine exhaust pipe and blocks the heat ray from the heat source, the cover being formed of a shaped composite in which aluminum alloy plates (2a, 2b) are layered on both the surfaces of a core foam resin (3b), respectively. The surface of one (2a) of the aluminum alloy plates in the shaped composite is provided to face the heat source (26).

Abstract: Provided in the present invention is a laminated plate in which a thin aluminum alloy plate having a remarkably lowered forming limit is laminated on each of the two sides of a core polypropylene based resin having foamable property which has inferior formability and shape stability, and which is able to be subjected to forming and is excellent in shape stability after this forming. A laminated plate 1 according to the present invention is one in which aluminum alloy plates 2a and 2b are laminated on each of the two sides of a core polypropylene based resin 3a having foamable property, and after forming, the core polypropylene based resin 3a having foamable property is foamed by heating, thereby forming a composite formed article. A plate thickness of this plated plate 1 is thin. Also, the aluminum alloy plates 2a and 2b and the core polypropylene based resin 3a having foamable property which constitute this laminated plate are each constituted so as to have a thin plate thickness.

Abstract: An extruder includes a barrel and a kneading screw extending through the barrel in a rotatable fashion. The kneading screw is provided with a devolatilization portion. The devolatilization portion includes a kneading flight that is twisted in a direction for transferring a material downstream. The kneading flight kneads the material while transferring the material downstream and separates a volatile component from the material. Impregnation sections, which allow the kneading chamber to be impregnated with the material, are respectively disposed adjacent to an upstream side and a downstream side of the devolatilization portion so that the air-tightness of the devolatilization portion of the extruder is maintained. Accordingly, an efficient devolatilization operation of the material is achieved.
