To provide a method for manufacturing an interdental cleaning tool that can prevent deformation of a core base at molding of a cleaning flexible part using an elastomer material, thereby effectively preventing occurrence of molding failure of the cleaning flexible part. The method in the present invention includes: a base part molding step of providing first metal molds 30 and 31 for molding base parts with a plurality of first molding spaces 32 aligned in parallel and including core base molding sections 32a and handle base molding sections 32b, providing the first metal molds 30 and 31 with connection part molding sections 35 to communicate with the adjacent handle base molding sections 32b, and supplying a synthetic resin material with a fiber material at a time to the plurality of first molding spaces 32 from gates 34 to form a plurality of base parts at a time; and a flexible part molding step of setting the core bases of the base parts into second metal molds, holding the core bases at two or more longitudinal portions by a plurality of pairs of hold pins in the second metal molds, each pair including two pins, and charging an elastomer material into the cleaning flexible part molding spaces.

The invention relates to a brush, in particular an interdental brush, which comprises a bristle-carrying stem defining a longitudinal direction and having an elongate support core, a bristle area having bristles projecting from the bristle-carrying stem, and a neck element connecting the support core to a handle, wherein the handle, the support core and the neck element are injection moulded integrally from a first plastics component, and wherein a second plastics component in the form of an integral layer and the bristles projecting therefrom is mounted on the support core. The invention also relates to corresponding product groups and to a corresponding method.

According to an embodiment of the present disclosure, provided is a method for manufacturing a bus bar in which a frame including a sensing part and a body part connected to the sensing part is prepared, the frame is inserted into and fixed to an injection molding mold, and an enhanced part enhancing the strength at a position where fatigue is concentrated by an enhancing injection material injected into the injection molding mold is formed in the frame.

Performed are an accommodation step of accommodating a pair of conductive members in a die, a sealing step of injecting a resin to seal the conductive members, and an extraction step of extracting a conductive member module. In the sealing step, the conductive members are sealed while a force is applied by the resin injected into the die to the individual conductive members in directions away from each other, and the individual conductive members are supported by support members disposed outside.

A molding method of a waterproof member is provided. The waterproof member is molded by molds and is for a coated electric wire. The molds include mold division surfaces including molding portions and electric wire mold clamping portions. The electric wire mold clamping portions are to sandwich the coated electric wire at sides of the molding portions. One of the electric wire mold clamping portions includes a convex portion and a side wall erected on an end of the convex portion. The other of the electric wire mold clamping portions includes a concave portion. One of the molding portions includes a side wall entering groove into which the side wall enters. The method includes molding the waterproof member accommodated in the concave portion with the waterproof member being pressed by the convex portion toward a direction in which one of the mold is attached to the other.

An injector for introducing a fluid includes a main body designed as an insert and including a first tool contact surface for an injection-molding tool and a second tool contact surface for the injection-molding tool; and an injection-molded housing that completely encloses the main body on at least one portion of the main body, the injection-molded housing including at least one first opening that extends linearly towards the main body.

An instrument panel unit (2) includes an instrument panel (3) and a decorative sheet (4). The instrument panel (3) includes a sticking portion (3a) and an exposed portion (3b). A plurality of insertion grooves (3c) and insertion holes (3d), into which bent pieces (4a) formed at rear end of the decorative sheet (4) are inserted, are formed alternately on a rear side end of the sticking portion (3a). A groove front-surface (3g) forming the insertion groove (3c) of the instrument panel (3) is formed in a tapered shape such that a width between the groove front-surface and an opposing groove rear-surface (3h) gradually increases upward. The bent piece (4a) of the decorative sheet (4) is thinner than a groove width at an upper part serving as an entrance part of the insertion groove (3c) and thicker than the groove width of a groove bottom-surface (3i) in the insertion groove (3c).

A process of overmolding a frame of a portable eyewear electronic device and a frame produced by the process is presented. A frame that includes a first material and includes a releasably mountable feature is attached to the mold in a desired position and does not contact other areas of the mold. The mold is filled with a second material to at least partially encase the frame insert.

A trim component for an interior of a motor vehicle has a film and has a carrier from a thermoplastic plastics material. The film has a relief structure, the carrier has a lattice structure having lattice members, and the carrier is back-molded on a rear side of the film such that the lattice members are connected in a materially integral manner to the rear side of the film.

A method for producing a secondary battery includes a space formation step and an injection molding step. In the space formation step, an outer periphery of a resin blocking portion with a quadrangular prism shape, in a terminal, is plugged to form a resin injection space around the terminal. In the injection molding step, a resin is injected into the injection space. The space formation step includes a constant-dimension pressing step and a constant-pressure pressing step. In the constant-dimension pressing step, a section between a pair of first outer peripheral surfaces of the resin blocking portion, extending parallelly to each other is pressed, whereby a distance between the first outer peripheral surfaces is brought to a predetermined distance. In the constant-pressure pressing step, a section between a pair of second outer peripheral surfaces of the resin blocking portion, extending in a direction intersecting the first outer peripheral surfaces, is pressed.
