A method for manufacturing a membrane switch member that can be manufactured easily and that can be caused to function as an electrostatic sensor even when a protruding portion is pressed. Injection molding by injecting a material including a supercritical fluid gas and a resin material in a mixed state; and, after the injection molding, removing a first mold from a second mold, causing gas produced within the injection molded resin to grow in concave portions, thereby causing the concave portions to invert to a protruding state; and manufacturing a membrane switch member in which voids are formed between the protruding portions and a molding resin layer, and portions other than the portions corresponding to the protruding portions are adhered to the resin layer by an adhesion layer.

A security closure 5 for a container neck 40 comprises a body 25 formed from a plastics material and a metal retention member 10 formed integrally with the body 25. The metal retention member 10 remains on the container neck 40 for retaining the body 25 on the container neck 40. The metal retention member 10 makes it impossible or very difficult to remove the security closure 5 from the container neck 40 without breaking/damaging/destroying the container. The security closure 5 and a container having a container neck 40, and a method of forming the security closure 5 are also disclosed.

An injection-molded container or shell, in particular a suitcase shell made of plastic, A) is made of foamed plastic and has gas channels and/or B) is made using physically or chemically foamed plastic and/or a plastic mixed with hollow fillers and/or C) is integrally made with wheel mounting axles and/or extendable rod buffers and/or extendable rod cavities.

A molding method for a synthetic resin molding that includes a molding body, a bent portion, and a flange. The bent portion and the flange are continuous in a longitudinal direction of the side edge. The flange includes a wide portion and a narrow portion. The molding method for the synthetic resin molding includes arranging a gate at a position corresponding to an end of one side of the flange in a longitudinal direction, setting a relationship S1S2, where S1 is a cross-sectional area of the wide portion of the flange, and S2 is a cross-sectional area of the narrow portion of the flange adjacent to and downstream from the wide portion in a flow of molten resin, and performing injection molding using a colored resin material containing a luster agent kneaded in the material.

A roof rail for a vehicle is provided that is made of only one piece and is solid across its length. The roof rail may be made using a co-injection molding process, a two-shot injection molding process or an extrusion molding process.

The invention relates to an injection-molding device for producing multi-component moldings from a thermoplastic molding compound, comprising a mold, forming a first article cavity, comprising means for filling the first article cavity with the thermoplastic molding compound, comprising an injection device for injecting a fluid against a projectile to be driven, wherein the injection device comprises a projectile carrier with at least one injection nozzle and with at least one projectile receptacle for a projectile as a displacer for the molding compound. The injection-molding device also comprises a mold insert, which forms a continuation of the first article cavity and encloses the projectile carrier, wherein the projectile carrier forms with the mold insert a second article cavity that can be filled with the molding compound, wherein the mold insert has a separate sprue and wherein the second article cavity of the mold insert can be sealed off for a time with respect to the first article cavity by means of movable mold parts. The invention also relates to a method for producing multi-component moldings by using the injection-molding device.

The invention relates to an injection molding device for manufacturing tubes having an internal thread, having a tool that forms an article cavity, having means for filling the article cavity with a thermoplastic molding compound, having an injection device for injecting a fluid toward a projectile to be driven through the article cavity, wherein the injection device comprises a projectile carrier having at least one injection nozzle and having at least one projectile receptacle for a projectile as a displacement member for the molding compound, wherein the projectile carrier at an end that is remote from the projectile receptacle is provided with a thread-bearing stamping core which is adjustable relative to the projectile carrier between a thread-forming first position and a demolded second position, wherein the stamping core in the thread-forming position plunges into the article cavity and seals the latter.

Described herein are injection molded containers and methods for in-mold labeling of the containers. More specifically, injection molded laboratory or medical containers such as centrifuge tubes, cryogenic tubes, blood collection tubes, sample holding tubes, and sample storage tubes, and methods for their mass production with in-mold labels is described.

The invention relates to a method for producing a tubular component as an article from a thermoplastic synthetic material while using an injection-molding device having a tool that forms an article cavity, having means for filling the article cavity with a thermoplastic molding compound, and having an injection device for injecting a fluid into the article cavity, wherein the injection device comprises a nozzle body, wherein the method provides that the nozzle body is used as a mold core for molding the shape of an end of the article, that the nozzle body is used as a carrier for an additional component to be incorporated into the article, wherein: a) the nozzle body first equipped with the additional component, b) the nozzle body is introduced into the closed article cavity, or the tool is closed around the nozzle body, c) the article cavity in a further method step is at least partially filled with the thermoplastic molding compound, d) a pressurized fluid is then induced into the article cavity by means of the injection device, wherein part of the molding compound is displaced into a secondary cavity, and e) the article is de-molded. The invention furthermore relates to an injection-molding device for carrying out the method.
