An implement having a base structure with a core component and a shell component that surrounds the core component. The core component may include a body formed of a rigid material and decorative elements embedded within the body. The shell component may be formed of a substantially transparent material so that the decorative elements of the core are visible through the shell component.

An injection-molding device for producing at least one tube head having a tube shoulder and a neck formed thereon has a press-out opening comprising a mold that defines a mold cavity and a nozzle that interacts with the mold. The nozzle has a valve needle that can be moved in the nozzle body. The valve needle is surrounded by a first flow channel, through which a first material component can be pressed out. The opening of the nozzle is closed by the valve needle head in a retracted position of the valve needle and released by the valve needle head in an advanced position of the valve needle In the advanced position of the valve needle, an annular outlet opening is formed, which establishes a fluid connection into the mold cavity together with an annular gap of the mold serving as a gate.

The invention relates to an operating-fluid container (1) for a motor vehicle, comprising a container body which is assembled from two mutually complementary injection-molded shells (2a, 2b) which consist of thermoplastic material and are welded together in an encircling manner to form a substantially closed hollow body, wherein at least one shell (2a, 2b) is at least in regions formed from thermoplastic materials having different strengths, wherein at least one part-region consists of a thermoplastic material having a fibrous filling, wherein the shell (2a, 2b) has been obtained by way of a co-injection process during injection molding.

A method of fabricating a vacuum insulated refrigerator structure includes injection molding a first layer of a first polymer material. A second layer of a second polymer material is injection molded over at least a portion of the first layer, and a third layer of a third polymer material is injection molded over at least a portion of the second layer to form a first component. At least one of the layers is impervious to one or more gasses. A second component is secured to the first component to form a vacuum cavity therebetween. The vacuum cavity is filled with a porous material, and the vacuum cavity is evacuated to form a vacuum. At least one of the first and third layers includes a structural reinforcement such as a rib or screw boss of increased thickness that is formed during the injection molding process.

A vehicle running board includes opposing vertical walls extending along a length of a tubular structure and including a carbon-fiber component. Opposing horizontal walls extend between the opposing vertical walls and include a glass component. The opposing vertical and opposing horizontal walls form the tubular structure having a generally rectilinear cross section. A polymer outer covering extends over the opposing vertical and opposing horizontal walls.

An oral care implement having a base structure with a handle portion and a head portion. In one aspect, the handle portion comprises a core component and a shell component that surrounds the core component. The core component may include a body formed of a rigid material and decorative elements embedded within the body. The shell component may be formed of a substantially transparent material so that the decorative elements of the core are visible through the shell component.

Methods and systems for co-extruding multiple polymeric material flow streams into a mold having a plurality of cavities to produce a plurality of multi-layer polymeric articles each having a consistent coverage of an interior core layer are disclosed herein. In an example method, a flow rate of a first skin material into a cavity is individually controlled for each cavity before initiation of co-injection of a second core material into the cavity, which may address inconsistent interior core layer coverage for articles from different cavities.

A manufacturing process is provided for a shoe with a fabric upper that is internally provided with a waterproof coating layer made of plastic material. The process includes the step of piercing of the upper in order to inject plastic material in an intermediate space between a core of a mold and the upper.

Provided are the following: a sandwich structure formed from a core component comprising a discontinuous reinforcing fiber, a thermoplastic resin and voids, and a skin component comprising a continuous reinforcing fiber and a matrix resin, wherein in the core component, 30% or more of the discontinuous reinforcing fiber is covered with the thermoplastic resin and monofilaments of the discontinuous reinforcing fiber intersect one another via the thermoplastic resin; an integrally formed article using the sandwich structure; and methods for the production therefor.

A vehicle running board includes opposing vertical walls extending along a length of a tubular structure and including a carbon-fiber component. Opposing horizontal walls extend between the opposing vertical walls and include a glass component. The opposing vertical and opposing horizontal walls form the tubular structure having a generally rectilinear cross section. A polymer outer covering extends over the opposing vertical and opposing horizontal walls.
