A hollow article such as an active bolster for an automobile is formed of an injection molded panel having a ridge and furrow adjacent a panel perimeter and an injection molded sheet having a bonding section at a sheet outer periphery, wherein the bonding section is within the furrow. An injection molded bond is formed between the bonding section and furrow, wherein a compression area where the sheet overlies a region of the panel adjacent the furrow is configured to constrain the bond to the furrow. An associated process and system facilitates mold alignment, part alignment, material strength, design adaptability, efficient processing, reduced labor, increased production rates, reduced energy consumption per part, aesthetically pleasing surfaces, and reduces or eliminates the need for a separate welding operation.

There is provided a liquid supply member capable of suppressing deformation of a liquid supply path and decrease in sealing property of a liquid supply path, during molding, and a manufacturing method of the liquid supply member. For that purpose, in die-slide injection molding that combines two components, a protection portion that protects a part of one component easily affected by heat and pressure, is provided on the other component.

An imaging lens assembly includes a dual molded optical element, a plurality of imaging lens elements and a light blocking element. The dual molded optical element has an object-side surface and an image-side surface and includes a light transmitting portion and a light absorbing portion. The light transmitting portion includes an optical effective section. The light absorbing portion is located on at least one of the object-side surface and the image-side surface of the dual molded optical element, and a plastic material of the light absorbing portion and a plastic material of the light transmitting portion are different colors. The imaging lens elements are disposed in the inner space of the imaging lens assembly. The light blocking element is disposed adjacent to the light transmitting portion of the dual molded optical element.

There is provided a manufacturing method of a liquid supply member capable of suppressing decrease in sealing property of a liquid supply path and deformation of the liquid supply path or the external shape. For that purpose, a manufacturing process of a liquid supply member prevents inflow of a molten resin into a concave portion of a portion other than a liquid supply flow path in a liquid supply member.

A decorative vehicle element has a contour light. The decorative element is produced as an integrally bonded composite from at least two plastics components in a multi-component injection molding process. A first plastics component consists of a material which can be galvanically coated or lacquered and forms the decorative element, and a second plastics component consists of a transparent or translucent and galvanically inert material and forms a contour light region through which light from an optical fiber element can pass. The second plastics component is located on a rear face of the first plastics component adjoining this face and partially covers the rear face of the first plastics component. An element component produced from the first plastics component performs fastening and fixing of the optical fiber located on the rear face.

A structural component, comprising at least two organo-sheet pieces which at least sectionally lie one on top of the other and which each include a fiber layer, wherein at least in the fiber layers of the organo-sheet pieces at least one pair of mutually aligned holes is formed, at which the organo-sheet pieces are positively connected to each other. There is furthermore proposed a method for manufacturing a structural component.

A molded part including a first member having a plurality of openings and a second member contacting with a peripheral edge of each of the plurality of openings so as to cover the openings, and having a hollow portion formed by sealing the contact portion with a sealing material, wherein: the second member defines a flow channel for filling the sealing material between the first member and the second member; the second member has a branched shape in which sections corresponding to positions covering the plurality of openings are branched from each other, and portions near a gate of the flow channel are connected as a common section; and the branched shape has a bridge structure for connecting the respective branched sections.

An object of the present invention is to suppress variations in shape of flow channels to have an enlarged flow channel. When an attachment main body 51 of a lid member 50 is attached to a recessed attachment part 46 of a main body member 40, a pair of flange parts 52 provided to the lid member 50 abuts on the main body member 40. Therefore, the insertion amount of the attachment main body 51 into the recessed attachment part 46 in each product can be maintained approximately constant while enlarging a main channel MC and a pair of sub channels SS1 and SS2, which are formed by the main body member 40 and the lid member 50, and variations in shape of these flow channels can be reliably suppress. The contact surfaces between the lid member 50 and the main body member 40 can be bent by providing the flange parts 52, and when forming a covering member 60, the molten resin can be prevented from leaking from the outside of the lid member 50 toward the main flow channel MS and the pair of sub flow channels SS1 and SS2, and as a result, variations in shape of the flow channels can be reliably suppressed.

A method is provided for producing a multi-section plastic component in which a first plastic injection-molded individual part and a second plastic injection-molded individual part are formed. The plastic injection-molded individual parts are joined by injecting a plastic moulding compound. The plastic molding compound is a non-elastomeric thermoplastic and forms a plastic connecting component following a curing process. The plastic injection-molded individual parts and plastic connecting component are then at least partially painted.

A method includes a first molding process and a second molding process performed repeatedly. The first molding process includes injecting resin into a first pair of molds, in which a first pair of divided pieces is formed and which is fitted together without an inner mold, to couple the first pair of divided pieces to form a first hollow article at an injection station. The second molding process includes (i) injecting resin into a third pair of molds, which is fitted together with one inner mold interposed therebetween, to mold a third pair of divided pieces at the injection station, (ii) taking out the first hollow article from the first pair of molds at a removing station, and (iii) removing another inner mold from a second pair of molds while leaving a second pair of divided pieces between the second pair of molds at the setup station.
