An injection-molding tool comprising at least two separate mold plates each having a mold insert socket with a mold insert attached in the mold insert socket. Each mold plate have mutually opposite and parallel abutting side faces defining the thickness of the mold plate and a number of mutually aligned guide bushings forming through holes adapted for axially sliding one of the mold plates with respect to the other on a common guide pin in a direction perpendicular to the abutting side faces of the mold plates. The guide bushings and the mold insert socket of at least one mold plate am interconnected via one or more connection plates each extending parallel to the abutting side faces and having a thickness of less than half the thickness of the mold plate.

Abstract:
A method of building an insulation system around a naked conductor section of a power cable. The insulation system includes an inner semiconducting layer arranged around the conductor, an insulation layer arranged around the inner semiconducting layer, and an outer semiconducting layer arranged around the insulation layer. The method includes: a) placing the naked conductor section in a mold, and b) molding an insulation system around the naked conductor section, wherein the molding of the insulation system involves injecting a first semiconducting compound into a first mold cavity to form an inner semiconducting layer around the naked conductor section, injecting an insulation compound into a second mold cavity to form an insulation layer around the inner semiconducting layer, and injecting a second semiconducting compound into a third mold cavity to form an outer semiconducting layer around the insulation layer.
Abstract:
A method of producing an injection molding tool for molding an article includes producing a replica of the article using at least one of an additive manufacturing process, a solid freeform fabrication process, or a computer numerically controlled (CNC) process. A support block is configured to receive at least a portion of the replica of the article and support the replica with at least one of an outer peripheral surface of the replica or an inner peripheral surface of the replica positioned at a spaced distance from a peripheral surface of the support block. The replica is supported inside the support block at the spaced distance, a ceramic resin material is introduced into the spaced distance and cured to form a ceramic shell insert, the insert is removed from the cavity and sintered, and the insert is positioned within the support block to form a part of a mold tool adapted for installation in a standard plastic injection molding machine.
Abstract:
The wire of the interdental treatment part is inserted into a shaft opening of the injection molding tool, preferably into a strip of the injecting molding tool such that said treatment part projects with a mounting section thereof into a cavity connected to the shaft opening. Preferably, a first cavity section is configured is configured on the strip, and a second cavity section is configured on a cavity body, to with the strip abuts at least during the injection molding process. After injection of plastic into the cavity, and after the at least partial curing thereof, the handle part thus formed is moved by a distance in the direction against the cavity along with the interdental treatment part, and the handle part is removed from the opened injection molding tool.
Abstract:
A rotary knob assembly and methods for forming and controlling friction effecting features of the knob assembly are disclosed. The knob assembly includes a mounting structure and a knob. The knob is rotatably coupled to a bezel of the mounting structure. The knob includes a stabilizer, a guide member, and a retainer having a patterned surface. At least a portion of the stabilizer is disposed between the bezel and the retainer to maintain an axial position and a radial position of the knob. A detent formed on the guide member cooperates with a patterned surface of the retainer to provide a haptic feedback to a user.
Abstract:
Disclosed herein is a display apparatus having high quality and high gloss. The display apparatus includes a display module which keeps a display panel on which an image is displayed in a curved surface state, a driving unit provided at a rear side of the display module, and a cover which accommodates the display module and the driving unit and forms an exterior of the display apparatus, wherein the cover is injection molded, and includes a first cover which is disposed in front of the display module and is provided to have the same curvature as that of the display panel, and a second cover which is disposed at the rear side of the display module, is coupled with the first cover, simultaneously accommodates the display module and the driving unit, and is formed to have a curvature which is different from that of the display panel.
Abstract:
A first part having an attachment having an elongated body configured to release from a second attachment of a second part under a desired force, and a method of manufacturing the same is provided. The first attachment includes a generally elongated body extending outwardly from the first wall with respect to the first support surface, the first wall further including at least one indent, the at least one indent formed on the first wall and open to a peripheral side edge of the elongated body, the indent extending into the wall a predetermined depth so as to provide the elongated body with a predetermined resiliency.
