Provided is an interdental cleaning tool which has a simple configuration and can effectively prevent an occurrence of breakage of a core base portion when inserting the interdental cleaning tool into an interdental space or during interdental cleaning without reducing productivity of the interdental cleaning tool, and provided is a method for manufacturing the interdental cleaning tool. An interdental cleaning tool (1) includes: a base portion (10) made of a synthetic resin; and a soft portion (20) made of an elastomer, the base portion (10) having a handle base portion (11) and a core base portion (12), the soft portion (20) having at least a cleaning soft portion (21) that covers the core base portion (12), in which a handle portion (3) as a grip is constituted by the handle base portion (11), and a cleaning portion (2) for interdental cleaning is constituted by the core base portion (12) and the cleaning soft portion (21), wherein two or more cleaning portion recesses (14) which penetrate the cleaning soft portion (21) and form core base portion recesses having a maximum depth d of 0.01 mm or more and 0.085 mm or less in the core base portion (12) are formed in each of a first side portion and a second side portion of the cleaning portion (2) at intervals in an axial direction of the cleaning portion (2).

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.

An injection mold having a cavity for receiving a plastics melt and having a temperature-control system. The cavity comprises a plate-shaped first part and a plurality of hollow cylindrical second parts arranged next to one another perpendicularly to the first part. The temperature-control system comprises temperature-control channels divided into channel portions for transporting a temperature-control medium and a first and a second temperature-control medium connection, with at least one first channel portion arranged in parallel with the first part. Second channel portions are connected by a first end to the first channel portion and by a second end to a first end of a third channel portion. Third channel portions are connected by a second end to a fourth channel portion. One of the second channel portions and the connected third channel portion are surrounded at least in part by one of the second parts of the cavity.

A wheel component, method, and tool device for a bicycle, including a plurality of integrally interconnected component parts, which form a spoked rim, wherein the rim and spokes are manufactured of a fibrous composite material by an injection molding process with fluid injection, wherein the liquefied fibrous composite material is injected into a cavity of a tool device, and a fluid is injected into the partially liquid fibrous composite material within the cavity to form at least one hollow space within the component part. A further component part forming a spoke, is manufactured by an injection molding process, wherein a mold core device for forming a hollow space within the spoke is disposed within a further cavity of the tool device. The fibrous composite material is injected into the further cavity. The mold core device is retracted from the fibrous composite material to form a cavity in the spoke.

An applicator for a cosmetic product on the skin or bristles having an application member, made of a thermoplastic elastomer material, the application member including a core extending along a longitudinal axis, and application elements formed at the surface of the application member, each of the application elements having a top with a width greater than 35 ?m and smaller than 450 ?m.

A mold insert and an injection-molding machine including the mold insert. The mold insert has at least one filament cavity and a stack of at least a first and second insert plates, wherein the first plate has a front face that closely abuts a front face of the second insert plate. A portion of the a filament cavity is provided in at least one of the front faces of the first and second insert plates such that the filament cavity is open at a top surface of the mold insert but does not extend to a bottom surface of the mold insert. A venting cavity is provided in the same front face of the insert plate in which the portion of the at least one filament cavity is provided.

A fluid manifold may include a body that may include a proximal end, a distal end, and a primary manifold component extending from the proximal end of the body to the distal end of the body and enclosing a primary channel. The fluid manifold may further include at least one auxiliary manifold component diverging from the primary manifold component and enclosing an auxiliary channel connected to the primary channel at a primary channel exit port. The fluid manifold may further include at least one compression valve region disposed along the body of the manifold where the compression valve region may be operable between an open position and a closed position.

A method for manufacturing a cylindrical brush of a cleaning tool, comprises a cylindrical brush having a core member, a plurality of rail plates, a plurality of polyvinyl alcohol (PVA) nodule foam bars and a pair of end caps. The core member includes an outer wall having a plurality of core holes and a pair of openings. The plurality of rail plates having a plurality of rail holes arranged along the outer wall of the core member. The plurality of polyvinyl alcohol (PVA) nodule foam bars is installed at each of the plurality of rail plates such that each of a plurality of nodules of the PVA nodule foam bar aligns with the plurality of core holes and with the plurality of rail holes. The pair of end caps encloses the pair of openings of the core member.
