Molding accuracy of a metal member is improved in an apparatus, a mold set, and a method for producing a metal-resin composite with a set of molds. An apparatus for manufacturing a metal-resin composite by press molding a metal member and a resin material, the apparatus including a mold including an upper mold and a lower mold sandwiching the metal member and the resin material, a molding auxiliary component detachably fixed to the upper mold so as to fill at least a part of a cavity C for arranging the resin material formed by the upper mold and the lower mold, and a drive unit that moves at least one of the upper mold and the lower mold in a vertical direction. The molding auxiliary component has a first press surface for molding the metal member. The upper mold has a second press surface for integrally molding the metal member and the resin material. A distance between the first press surface and the lower mold in a state where the molding auxiliary component is attached is shorter than a distance between the second press surface and the lower mold in a state where the molding auxiliary component is removed.

A golf club head includes a club face and a body. The club face is formed from a metallic material and includes a first, hitting surface, a second, rear surface that is opposite the first surface, and a flange that is separated from the second surface by a transverse distance. The body is formed from a polymeric material and includes a crown, a sole, a hosel, and a face support. The club face and the body cooperate to define a closed volume, and the face support extends to opposing sides of the flange and is operative to couple the club face to the body.

A thermoplastic resin composition and a molded article including the same can include 100 parts by weight of a base resin including 10 to 50% by weight of an acrylate-aromatic vinyl compound-vinyl cyanide compound graft copolymer (A-1) containing acrylate rubber having an average particle diameter of 0.3 to 0.5 μm, 5 to 40% by weight of an acrylate-aromatic vinyl compound-vinyl cyanide compound graft copolymer (A-2) containing acrylate rubber having an average particle diameter of 0.05 μm or more and less than 0.3 μm, and 20 to 65% by weight of an aromatic vinyl polymer (B), and 0.5 to 12 parts by weight of a polyamide (C). The thermoplastic resin composition can have a solvent resistance of 15 days or more.

A composite oil pan for a work vehicle engine and a method of forming the composite engine oil pan include forming a sheet of metal into a first pan and open molding a fiber-reinforced polymer resin onto the first pan forming a second pan. The first pan has a first bottom wall and first peripheral walls extending from edges of the first bottom wall to define a sump, the first peripheral walls terminating in a first peripheral flange. The second pan has a second bottom wall and second peripheral walls abutting the first bottom wall and the first peripheral walls, the second peripheral walls terminating in a second peripheral flange. The first pan defines a thin metal structure with an inner surface extending across the first bottom wall, first peripheral walls and first peripheral flange; the second pan reinforces the first pan without abutting the inner surface.

Methods of embedding an elongate susceptor within a thermoplastic body and systems that perform the methods are disclosed herein. The methods include extending the elongate susceptor such that an extended portion of the elongate susceptor extends between a guide structure and a body-contacting structure. The methods also include heating a segment of the elongate susceptor to produce a heated portion of the elongate susceptor. The methods further include pressing a leading region of the heated portion of the elongate susceptor through a body surface of the thermoplastic body and into the thermoplastic body. The methods also include operatively translating at least one of the guide structure, the body-contacting structure, and an application tool that includes the guide structure and the body-contacting structure along an embedment pathway for the elongate susceptor.

A method of manufacturing a fluid control device includes extruding a polymer melt into a chamber defined by an outer surface of a support structure and a disintegrable metallic tubular member disposed at the support structure, the polymer melt comprising a high heat polymer and a foaming agent, the high heat polymer having a heat deflection temperature of about 100° C. to about 300° C. measured at 1.82 MPa in accordance with ASTM D648-18; sealing the chamber; and foaming the high heat polymer to produce a porous filtration medium in a compacted shape.

Disclosed is a panel for an aircraft structure, including a laminated skin of layers of metal of which in each case two are joined together by a fibre-reinforced adhesive layer, as well as a laminated doubler of layers of metal and at least one fibre-reinforced adhesive layer in each case between two layers of metal, wherein the doubler has a smaller size of perimeter than the skin and is bonded to an outermost layer of metal of the laminated skin by a fibre-reinforced supplementary adhesive layer, with the feature that at least one part of the perimeter of the fibre-reinforced supplementary adhesive layer is staggered inwards relative to the corresponding perimeter of the doubler and that that part of the inwards-staggered perimeter of the fibre-reinforced supplementary adhesive layer is delimited by a glued edge. Also disclosed is a method for manufacturing such a panel.
