Durably sealing connection between insert and polymer and production method therefor
The invention relates to a method (100) for establishing a connection between an inlay (1, 1′, 1″) and a polymer (3) at least partially surrounding the inlay, wherein a monomer (2) is brought into contact (110) with the inlay (1, 1′, 1″) and is subsequently polymerized (120) to form the polymer (3), wherein the temperature TE of the inlay (1, 1′, 1″) is increased (130) at least briefly at least to that temperature TM that the monomer (2) assumes at its maximum during its exothermic polymerization (120) to form the polymer (3), and/or that ensures that the heat flow always runs from the inlay (1, 1′, 1″) to the monomer (2). The invention also relates to a method (200), (300), (400) for the sealing integration of an inlay (1, 1′, 1″) in a component (5). The invention also relates to a device (50) for carrying out the method (100), comprising a conveyor (51) for a lead frame (11) in which a multiplicity of inlays (1, 1′, 1″) are able to be fed, and an at least two-part (52a, 52b) mould (52) which is closable about an individual inlay (1, 1′, 1″) and has a feed (53) for feeding the monomer (2) into the space (54) between the mould (52) and the inlay (1, 1′, 1″), wherein a current supply (55) is provided for the resistive and/or inductive heating (131) of the inlay (1, 1′, 1″) surrounded by the mould (52).
Metal-resin bonded member and method of manufacturing the same
An object is to provide a metal-resin bonded member that is easy to manufacture and has high bonding strength. The metal-resin bonded member includes a metal body having an iron oxide layer on the surface and a resin body bonded to the metal body via the iron oxide layer. The iron oxide layer has a thickness of 50 nm to 10 μm. The iron oxide layer comprises 60-40 at % Fe and 40-60 at % O at the outermost surface side. The iron oxide layer contains magnetite (Fe.sub.3O.sub.4). The iron oxide layer is formed by heating the surface of an iron-based substrate at 200-850° C. in an oxidation atmosphere. The resin body is composed of polyphenylene sulfide (PPS). The bonding of the metal body and the resin body via the iron oxide layer can be carried out by insert molding, thermal adhesion utilizing friction heating, etc.
Method of manufacturing composite member and the composite member
A method of manufacturing a composite member including an aluminum member and a resin member bonded to each other, the method including: performing blasting on a surface of the aluminum member; modifying the surface of the aluminum member into aluminum hydroxide, the modifying including causing the surface of the aluminum member having undergone blasting to react with water by using at least one of heat and plasma; and directly bonding the resin member to the surface of the aluminum member modified to the aluminum hydroxide.
MAGNESIUM ALLOY/RESIN COMPOSITE STRUCTURE AND METHOD FOR MANUFACTURING THE SAME
A magnesium alloy/resin composite structure (106) including a magnesium alloy member (103) and a resin member (105) integrated to the magnesium alloy member (103) and made of a thermoplastic resin composition, in which the magnesium alloy member (103) surface to which the resin member (105) is not integrated is coated with a layer including a manganese atom, an oxygen atom, and a sulfur atom.
JOINED BODY
To reduce concern of separation due to a user's unintended application of a load.
A joined body of a first structure member having a frame-like structure and a second structure member joined to an inside of the first structure member, wherein the first structure member has a protruding portion in which an anchor shape is formed, the second structure member has a hole portion that comes into contact with the protruding portion of the first structure member, and the protruding portion has a stress concentration portion on which stress concentrates when a load is applied to the second structure member.
Board and method of producing the same
A board includes fibers and thermoplastic resin and has a first surface and a second surface that is opposite from the first surface. The board includes a flat body member having edges, a bent portion, a hole, and a filling portion that is made of thermoplastic resin and in the hole. The bent portion extends from one of the edges of the flat body member and includes an edge of the board. The bent portion includes an angled portion that extends along the one of the edges of the flat body member and the bent portion extends from the angled portion at an inclination angle with respect to the flat body member such that the first surface of the angled portion is stretched. The hole is in the first surface of the angled portion.
LIGHT-WEIGHT GEAR AND MANUFACTURING METHOD THEREOF, MANUFACTURING METHOD OF GEAR TRAIN, AND ROBOT
A light-weight gear including: an annular tooth portion made of metal; a shaft extending along a central axis of the tooth portion and made of metal; and a coupling element configured to couple the shaft to the tooth portion and made of a resin, in which a joining part between the shaft and the coupling element and a joining part between the tooth portion and the coupling element are provided with irregularities configured to be engaged with one another in a circumferential direction, and corners of the irregularities are rounded to release a stress. Also, provided is a manufacturing method of a light-weight gear including: disposing the tooth portion and the shaft in a mold and injecting a molten resin into a cavity of the mold, thereby simultaneously performing injection molding of the coupling element and joining the coupling element to the tooth portion and the shaft.
