By using a forming die having a fixed die and a movable die moving along a parting surface on the fixed die and by moving the movable die along the parting surface, to press and hold a sintered part between the movable die and the fixed die, to form a cavity around the sintered part except parts which abut on the fixed die and the movable die by the forming die, and to fill the cavity with melted material which becomes an exterior part, so that the sintered part and the exterior part are integrated by insert molding.

A halter snap includes a hook member serving as a primary molded product and a holder member serving as a secondary molded product, the hook member and the holder member being injection-molded from resin and rotatably coupled to each other. The primary molded product includes a shaft formed irreducible in diameter. The secondary molded product includes a bearing portion coupled to the shaft and formed unincreasable in diameter. The shaft is configured to rotate after being moved in an X-axis direction from a state where the shaft is contact-coupled to the bearing portion. The hook member and the holder member include POM.

The invention relates to a damper bearing comprising a hollow housing (1) for receiving a damping element (5) and a cover (3) for fixing the damping element (5) in the housing (1), wherein the housing (1) and the cover (3) are manufactured from plastic and the connection between the housing (1) and the cover (3) is produced integrally by a welding process, which is based on a relative movement between the housing (1) and the cover (3). The invention furthermore relates to a method for producing a damper bearing according to the invention, in which the housing and the cover are brought into contact at contact surfaces provided for this purpose, and a relative movement between the housing and the cover is then generated, which causes the housing and the cover to be integrally welded as a result of the energy input into the contact surfaces.

A composite material structural member including a core member, composite material members, and at least one composite material sheet. The members are disposed around the core member and are adhered to each other to form a hollow space. The composite material sheet is disposed between the core member and the members so as to overlap the bonded portion between the members. The composite material sheet forms a hollow composited structure together with the members.

An object including a. a fiber reinforced plastic and b. a ceramic material, wherein the ceramic material is prepared by plasma electrolytic oxidation of aluminium. A process for the preparation of the object, including the steps of a. providing aluminium, a fiber reinforced plastic and a resin, or providing aluminium and a precursor of a fiber reinforced plastic comprising fibers and a resin, b. treating, at least partially, the aluminium with plasma electrolytic oxidation to provide a ceramic material, c. attaching the ceramic material to the fiber reinforced plastic with the resin, or attaching the ceramic material to the fibers with the resin, d. curing the resin to provide the object including the fiber reinforced plastic and the ceramic material at least partly bound to the fiber reinforced plastic.

A flexible bearing assembly includes at least one metal end ring, a flexible bearing core having a plurality of layers of a resilient material between layers of a reinforcement material, and a phenolic composite material between and bonded to each of the at least one metal end ring and the flexible bearing core. A rocket motor assembly includes a chamber configured to contain a propellant and a movable thrust nozzle coupled to the chamber. The movable thrust nozzle includes a phenolic composite material between and bonded to each of a metal end ring and a flexible bearing core. Methods of forming a flexible bearing assembly include bonding a phenolic composite material to at least one metal end ring and bonding a flexible bearing core to the phenolic composite material. The flexible bearing core includes a plurality of layers of a resilient material between layers of a reinforcement material.

A component part has an over-molded integrally formed insert member. The insert member has a predetermined feature. In addition, an end portion of the predetermined feature is exposed and free from over-molding.

A bearing assembly includes a bearing unit formed from a stationary bearing ring configured to be connected to a stationary component and a rotatable bearing ring configured to be connected to a rotatable component and a bearing carrier connected to the stationary bearing ring in a rotationally fixed manner, for example, by overmolding. The bearing carrier includes at least one notch that exposes at least one section of the stationary bearing ring.

A three-dimensional printing apparatus for forming a three-dimensional object is provided. The three-dimensional printing apparatus includes a forming unit to supply a powder to form a powder layer and a head to eject liquid droplets of a forming liquid onto the powder layer to bond particles of the powder layer to form a forming layer. The forming unit and the head form laminated forming layers by sequentially repeating forming the powder layer and ejecting the forming liquid to form a between-layers vacant space formed between the two successive forming layers sequentially laminated in the laminating direction.

In a method of manufacturing a sliding member including a polyamide resin and a filler, a compound having a carbodiimide bond is supplied during kneading of the polyamide resin and the filler.
