A hot runner nozzle for the lateral gating of plastic components has a nozzle body and a pressure lid. Tip elements are arranged between the nozzle body and the pressure lid, which are each inserted into a recess of the nozzle body and are each penetrated by a movable closure needle having a tip, which in at least one operating position protrudes in each case over an outer circumferential edge of the nozzle body. The closure needles each include, on their ends facing away from the tip, a coupling means, which is coupled to a drive means for moving the closure needles. The tip elements are supported on their side facing away from the respective tip of the closure needles on a buttress element inserted between the nozzle body and the pressure lid.

An injection molding machine includes an edge gate nozzle with a nozzle body having a primary melt channel and a nozzle head having first and second secondary melt channels that feed melt to first and second nozzle tips. First and second heaters are disposed in the nozzle head to provide heat to the secondary melt channels. In some embodiments, the heaters are positioned adjacent to the secondary melt channels, with first heater is closer to the first secondary melt channel than to the second secondary melt channel. In some embodiments, the heaters are positioned adjacent to the nozzle tips, with the first heater closer to the first nozzle tip than to the second nozzle tip. In some embodiments, each heater is adjacent to both the respective nozzle tip and secondary melt channel. In some embodiments, each heater is individually controllable.

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).

An angle gating injection molding apparatus is disclosed. The apparatus includes a gate axis misaligned with a cone axis of a nozzle tip.

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.

A method relates to manufacturing an in-mold decorative molded product including a transfer layer formed on a surface of an injection-molded product. The method includes 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 molding resin into the molding injection space and a structure for holding the in-mold decorative molded product; and forming the in-mold decorative molded product by filling the molding injection space with the molding resin and then opening the first and second molds. When the base film is separated from the in-mold decorative molded product by opening the first and second molds, a peeling weight varies depending on a portion in an end part of the in-mold decorative molded product.

A side-gate injection molding apparatus and a side-gate nozzle assembly are disclosed. The side-gate nozzle assembly delivers moldable material to a cavity insert that is beside the side-gate nozzle assembly. The side-gate nozzle assembly includes a nozzle body having a nozzle flow channel and a widthwise slot extending across a downstream side of the nozzle body. The nozzle flow channel has an outlet that ends at a wall of the slot. A load component is received in the slot and has a load component flow channel in fluid communication between the nozzle body outlet and an outlet at an end of the load component. A side-gate tip assembly is adjacent to the end of the load component and is in fluid communication between the load component flow channel and the cavity insert. In operation, thermal expansion of the load component presses the side-gate tip assembly towards the cavity insert.

A manifold device for an injection-molding nozzle for an injection-molding tool has a main manifold channel for an injection-molding compound, which main manifold channel extends from an inlet opening into the manifold device as far as at least two transfer openings, and at least two manifold channels for the injection-molding compound, which manifold channels each extend from a transfer opening to an outlet opening and are each fluidically connected by a transfer opening to the main manifold channel. Also disclosed are an injection-molding nozzle with such a manifold device and an injection-molding tool with such an injection-molding nozzle.

The dust proof sleeve comprises a rubber tubular bellows part (1) with an opening at both ends for sliding onto an element fitted with the dust proof sleeve. The bellows part (1) comprises an accordion-shaped undulated wall with circumferential peaks (2) and circumferential valleys (3). The dust proof sleeve further comprises at least one reinforcement (4), which is arranged at least along a part of the circumference of the bellows part (1) and adjoins the circumferential shape of the bellows part (1). The at least one reinforcement (4) is at least partly integrated in the bellows part (1) by vulcanization. The invention further comprises a dust proof sleeve production mould and a dust proof sleeve production method.
