To manufacture a motor vehicle composite component, plastic particles are introduced into a mold cavity of a mold and are connected there to one another to form a particle foam. The mold is then adjusted while the mold cavity changes, and a thermoplastic plastic is then injected into the mold cavity while a carrying element and/or at least one fastening element are formed, wherein the thermoplastic plastic is bonded to the particle foam at least by connection in substance. The aforementioned materials may also be introduced in the reverse order. The mold is then adjusted once again while the mold cavity changes, and a metal melt is then injected into the mold cavity, as a result of which an electrical strip conductor and/or at least one metallic fastening element are formed.

An injection-molding process for injecting a shoe soling including at least two adjacent injection-molding layers onto a shoe upper drawn over a shoe last, uses a mold cavity including a frame, the cavity being covered at the top by the upper also serving as a mold cover, with plastic material being injected into the cavity below the upper. To produce two adjacent injection-molding layers of plastic materials having different properties and reaction times in one operation, i.e. without needing an interim mold opening, before covering the cavity a film is clamped over it by a clamp mounted on the frame. When filling the cavity, the space below the film is first filled with plastic material to produce the first injection-molding layer and then, to produce the adjacent second injection-molding layer, the space above the film is filled with plastic material. Plastic materials are used that inseparably attach to the film.

A method of manufacturing a biocompatible polymer-based microneedle, the method comprising: (a) a primary filling step of covering, by stoppers, upper sides of multiple holes, which are formed to be spaced apart from one another, penetrate a mold, and each have a conical shape, and injecting a biocompatible polymer solution containing an appropriate amount of active ingredient by using filling needles; (b) a secondary filling step of injecting a biocompatible polymer solution containing an excipient by using the filling needles; (c) a step of solidifying the biocompatible polymer solution; and (d) a step of attaching a pad to an upper portion of the mold and then detaching the pad from the mold. The microneedle manufactured by the present invention may solve problems of degeneration of medicine, insufficient hardness, and a loss of medicine caused by a complicated process and a long manufacturing time.

An injection mold for producing a double walled drinking vessel includes first and second mold portions. The first mold portion forms a first and second cavities corresponding to the outer shape of the outer container and the outer shape of the inner container, respectively. The first and second cavities are located concentrically with respect to a central axis. An index plate is rotatable and axially movable along the central axis relative to the first mold portion. The index plate includes a first core and a second core. The first cavity has a first cavity injection gate for injecting mold material into the first cavity for forming the outer container. The second cavity has a second cavity injection gate for injecting mold material into the second cavity for forming the inner container. The first cavity has a further injection gate for injecting joint material for joining the outer and inner containers.

An active grille shutter system (AGS) that is assembled from modular components, thereby allowing the AGS to be any desired width or height when assembled. This allows for the creation of different sized AGS for different vehicle platforms, while assembling the AGS from a stock of components that is common to each AGS. The invention is also directed to a method of forming a base integrated end cap with moveable vane retainers and a link arm using a two shot molding process.

An optical lens assembly has a central axis and includes at least one dual molded lens element. The dual molded lens element includes a light transmitting portion and a light absorbing portion, wherein the light transmitting portion includes an optical effective region and a lens peripheral region, and the lens peripheral region surrounds the optical effective region. The light absorbing portion surrounds the optical effective region. The light transmitting portion and the light absorbing portion are made of different plastic materials with different colors, and are integrally formed by an injection molding. The light transmitting portion or the light absorbing portion includes a plurality of annular convex structures, and the annular convex structures surround the central axis.

The invention relates to a method for producing a trim part (10) for vehicles, using an injection mold (1), in which an edge of a carrier substrate is formed by the surface cover layer (8) reaching around said edge by means of a lost seal molded to the carrier substrate.

A footwear article forming process, and a device for the same are disclosed. The process includes: providing a forming mold set including an outer modular mold, an inner formation mold, and a footwear-forming space therebetween. The footwear-forming space comprises a footwear lower portion forming space and a footwear main portion forming space. Footwear article forming steps are as follows: injecting a pre-determined amount of a footwear main portion rubber material into a footwear main portion sprue channel, the footwear main portion rubber material being injected from a footwear main portion rubber injection opening into the footwear main portion forming space via a transfer injection channel; and placing a footwear lower portion rubber material into the footwear lower portion forming space.
