A method of manufacturing an in-mold decorative molded product including a transfer layer formed on a surface of an injection-molded product, the method including: inserting in a first mold for injection molding an in-mold transfer film including the transfer layer disposed on a base film; forming a molding injection space by mold clamping of the first mold and a second mold including a structure for injecting a resin into the molding injection space and a structure for holding a molded product; and forming a molded product by filling the molding injection space with a molding resin and then opening the second mold and the first mold, wherein when the base film is separated from the in-mold decorative molded product integrated with and the transfer layer by opening the molds, a peeling weight varies depending on a portion in an end part of the in-mold decorative molded product so that a peeling starting point is generated from a position with a light peeling weight in the in-mold transfer film to peel the in-mold decorative molded product from the in-mold transfer film.

The invention is directed to an injection nozzle (1) for an injection molding device comprising. At least one closure element (4) is arranged movable in a nozzle head (2) in a first direction (a). A cam mechanism (5) comprises a cam head (6) with a cam head block (7). Per closure element (4) the cam head block (7) comprises a bracket (8). The bracket (8) comprises at least one inlay (9). Per closure element (4) the at least one inlay (9) comprises a first drive surface (10) which interacts with a second drive surface (11) arranged at the closure element (4) at least during closing of the closure element (4). The cam head block (7) per closure element (4) comprises a third drive surface (12) which interacts with a fourth drive surface (13) arranged at the closure element (4) at least during opening of the closure element (4).

A needle-equipped syringe reduces an inclination of a needle by reducing an inclination of a core pin when insert molding is performed. The needle-equipped syringe includes a barrel formed using a resin and having a cylindrical body, a nozzle part provided at a distal end of the body, and an opening part provided at a proximal end of the body; and an injection needle held by the nozzle part. The injection needle and the barrel are integrally molded so that an axis of the injection needle is substantially parallel to an axis of the body. The body has a thick part and a thin part located at a proximal end of the body at opposing positions across the axis of the body. At the proximal end of the body, an axis of an inner surface of the body is offset from an axis of an outer surface of the body.

Disclosed is a side-gate nozzle having a nozzle body, a nozzle tip and a transfer member. The nozzle body includes a heater, a longitudinally extending nozzle channel, and a bore extending from an exterior side wall of the nozzle body to the nozzle channel. The nozzle tip includes a tip member, a tip channel extending therethrough and a sealing member surrounding the tip member and in which the tip member is received. The transfer member seats against a step in the bore in the nozzle body and includes a bearing surface against which the nozzle tip is slidably seated and a transfer channel extending therethrough in fluid communication between the nozzle channel and the tip channel. In operation thermal expansion of the transfer member along its length applies a sealing force against the nozzle tip.

Provided is a method for manufacturing an interdental cleaning device (1) including a base portion (10) having a handle portion (11) and a core portion (12); and a soft portion (20) having a cleaning soft portion (21), a non-slip portion (22), and connecting portions (23) extending from two sites of the non-slip portion (22) and being connected to the cleaning soft portion (21). The method includes causing a second gate (49) of second molds (40) and (41) for molding the soft portion (20) to open at a position substantially equally distant from positions of two communicating openings (48a) of a non-slip molding space (47) for molding the non-slip portion (22), the two communicating openings (48a) communicating with connecting portion molding spaces (48) for molding the connecting portions (23); and charging the elastomeric material from the second gate (49) into a second molding space (42) for molding the soft portion (20) to fill the molding space (42).

Actuator for a hot runner injection molding apparatus, comprising at least one nozzle for side gating with at least one valve gate comprising a valve pin for closing a communication opening in a mold cavity, a valve pin actuating means coupled with the at least one valve pin, which is moveable back and forth along a first axis (A), whereby the at least one valve pin is moveable along a second axis (B), which is arranged at an angle () to the first axis (A), and an actuator for driving the valve pin actuating means. The available speed of moving the valve pins and the possibility of multiple locations of positioning the valve pins relative to the mold gates ensures a a reduction of the injection pressure in the mold cavity and thus a reduction of mold core shifting, the possibility to fill at the same time mold cavities of different sizes and allows for defect free molded parts.
