To provide a method of manufacturing a shaft-shape composite member in which a bent section is suitably treated. A plurality of thermosetting fiber-reinforced resin materials made of a UD material is supplied to a bending section of a mold in a state of being aligned in parallel to an axial direction of a cavity to form a UD material layer. Subsequently, after forming a tubular member having the UD material layer by the metal mold, by thermally curing the tubular member, the shaft-shape composite member having the bent section can be obtained. When manufacturing the shaft-shape composite member, a cross-section orthogonal to the axial direction of each of the fiber-reinforced resin materials has a circular shape.

The invention relates to a method for producing a tubular hollow body (1) with at least three pipe openings, partly or completely consisting of plastics material. It is provided that a lost core pipe (9), which has a connection opening (13, 14) on each of its ends and has at least one docking opening (11) along its length, is produced, that the core pipe (9) is introduced into a cavity of a mold, with two non-lost core pieces (17, 18) being arranged with one of their ends (3, 4) respectively against the connection openings (13, 14) in a sealing manner and a non-lost core part (19) being arranged with one end against the docking opening (11) in a sealing manner, in that plastics material (25) is then introduced into the mold cavity to encapsulate the core pipe (9), the core pieces (17, 18) and the core part (19) and that, once the plastics material (25) has cured, the core pieces (17, 18) and the core part (19) are withdrawn from the hollow body (1) created. The invention also relates to a corresponding hollow body (1).

A tool includes a head that extends form the flexible section, an emitter within the head; and a nozzle to eject a cooling fluid therefrom. A method of additively manufacturing a component including delivering series of thermal shocks to a conglomerated powder within an internal passage of an additively manufactured component to facilitate removal of the conglomerated powder.

A filler neck assembly including a main channel for supplying a liquid into a tank and an auxiliary channel for evacuating gas from the tank. The main channel includes a tubular main body including a first end receiving a filler spout and a second end discharging the liquid into the tank. The auxiliary channel includes a first section and a second section, the first section being a channel integrally molded with the tubular main body, and the second section being formed by a feature on an exterior of the main body cooperating with a separately formed part.

A method for producing a tube arrangement (1) for the transport of tempering medium, in which base body sections (6, 7) are provided, which have congruently configured separating surfaces (8), wherein at least one functional element (3) on at least one base body section (6, 7) is arranged in such a way that it can be in contact with the tempering medium, whereafter the base body sections (6, 7) are joined along the separating surface (8) and bonded to one another to form the tube arrangement (1).

A core metal includes, on an outer circumference thereof, a plurality of attachment surfaces to which a plurality of strings are attached, and a plurality of guided portions are formed along an axial direction of the core metal and disposed between two of the attachment surfaces. A string supply device includes a string supply unit that supplies the strings to the outer circumference of the core metal, an attaching unit that arranges and attaches the strings on the attachment surfaces of the core metal in a circumferential direction of the core metal, and a plurality of guiding units, in contact with the guided portions of the core metal, which guides the core metal.

A nylon tube automatic thermoforming apparatus includes a main body, a conveying assembly, a heating assembly and a tube bending assembly. The heating assembly includes an oven communicated with the conveying assembly and an electrically heated cylinder arranged between the oven and the tube bending assembly. A heating coil is arranged in the electrically heated cylinder. A nylon tube is conveyed from the conveying assembly and enters the tube bending assembly via the oven and the heating coil. The electrically heated cylinder and the tube bending assembly are arranged outside the main body. A nylon tube shaping process includes the steps of drawing, heating inside a main body, heating outside the main body, bending, staying, feeding, angle adjusting, repeating the above steps until the length and the curvature of the nylon tube meet the requirements, and cutting off.

A method of sub-ambient pressure processing of blow-molded polymer foams and skin-over-foam sandwich panel configurations for lightweight components having improved structural properties. The method can create either skinned or un-skinned foams that offer smooth interior and exterior surfaces, zero or controlled surface porosity, skins of pre-defined thickness, and foam cells that are expanded and oriented normal to the material plane, effectively spherical or polyhedral in nature, and offering improved bending and compressive strength.

An object of the present invention is to propose a bending die capable of creating a product without causing buckling, even if the shape of the product is long or bent freely in three-dimensional space. The bending die according to the present invention is a bending die having a smooth shape formed by virtually and continuously moving, in three-dimensional space, a profile including a substantially circular-shaped first closed curve having a recess portion, wherein an opening width b of the recess portion is shorter than a groove width a of the recess portion, a tube insetting portion is formed by the recess portion, and the smooth shape is realized and created in real space using a three-dimensional printing technique.

The disclosure relates to a method of manufacturing a component composed of a thermoplastic having at least one hollow space in the interior for a two-wheeler by means of plastic injection molding, said method comprising the following steps: closing the configured injection molding tool; injecting a plasticized thermoplastic melt into the closed injection molding tool; injecting at least one fluid into the closed injection molding tool to displace the plastic core from the interior of the component; and opening the injection molding tool and demolding the component. wherein the component is a handlebar.
