A method for forming a fiber-reinforced thermoplastic control surface includes forming first and second skins from a fiber-reinforced thermoplastic resin. The method further includes overmolding fiber-reinforced thermoplastic features onto the first skin and/or second skin, including stiffener structures, sidewalls, and/or hinges. The method further comprises welding or consolidating the first and second skins together, along with the associated internal features overmolded thereon to form a single-piece, stiffened, fiber-reinforced thermoplastic control surface.

This injection-molded article is an injection-molded article using a cellulosic fiber composite resin, including: a resin insert piece including a colorant or a cellulose fiber; a first region formed of the cellulosic fiber composite resin; and a second region formed along a weld line of the cellulosic fiber composite resin extending from the resin insert piece, in which the first region and the second region have different color tones.

A fiber reinforced thermoplastic resin molded article contains inorganic fibers (A), organic fibers (B), and a thermoplastic resin (C), the fiber reinforced thermoplastic resin molded article containing 5 to 45 parts by weight of the inorganic fibers (A), 1 to 45 parts by weight of the organic fibers (B), and 10 to 94 parts by weight of the thermoplastic resin (C), based on 100 parts by weight of the total of the inorganic fibers (A), the organic fibers (B), and the thermoplastic resin (C), the inorganic fibers (A) in the fiber reinforced thermoplastic resin molded article having a weight average fiber length (L.sub.wa) of 0.01 mm or more and 3 mm or less, the organic fibers (B) having a weight average fiber length (L.sub.wb) of more than 4 mm and 20 mm or less.

Provided is a method for manufacturing a fiber reinforced resin molded article capable of effectively reducing the occurrence of a preform with poor resin impregnation, and such a manufacturing device thereof. After it is detected that a predetermined amount (the same amount) of resin has been individually poured into a plurality of cavities provided in a mold, the fiber layers of preforms are impregnated (compressively filled) with resin. Pressure sensors for detecting a resin injection amount are used. When closing runners, a small gap is formed in the runners.

Wood-plastic hybrid component for use in a motor vehicle having a multi-component structure including a wood subsection, at least one water-impermeable plastic coating, arranged directly on the wood subsection for protecting the wood subsection, and a plastic subsection. The water-impermeable plastic coating is at least partially directly adjacent to the plastic subsection.

A casing member for an in-vehicle camera, obtained by injection molding a resin composition that comprises 100 to 300 parts by mass of a total of a fibrous inorganic filler and a non-fibrous inorganic filler to 100 parts by mass of a polyarylene sulfide resin and has a content of an elastomer of 10% by mass or less, and satisfying the following conditions (A) and (B). (A) When a molded product of a predetermined shape is injection molded using the resin composition under predetermined conditions, an absolute value of (shrinkage rate in a direction perpendicular to a flow direction)−(shrinkage rate in the flow direction) is 0.5% or less. (B) A water absorption rate of a molded product of a predetermined shape that is injection molded using the resin composition under predetermined conditions is 0.3% or less when subjected to a predetermined hot water immersion test.

An improved method for obtaining high fiber volume fraction, long fiber injection molded articles is provided. According to one embodiment, the method includes forming an injection molding feedstock by cutting pre-impregnated fiber-reinforced tape into platelets. The platelets can be coated with a thin layer of polymer to allow sliding of the platelets with respect to each other at the early stages of plastication, rather than forcing relative motion of fibers with respect to each other. The method can further include the dispersion of material only in the final stages of the injection molding screw to promote gentle motion of the feedstock at the earlier stages of the plastication process. The method allows improvement of mechanical properties of articles manufactured with equipment and techniques that are prevalent in high volume automotive and consumer industries.

An injection molding apparatus includes a fixed die having a first gate opening and a second gate opening formed therein, a movable die configured to be clampable to the fixed die, a first injection unit that injects a first molding material into a cavity defined by the fixed die and the movable die via the first gate opening, and a second injection unit that injects a second molding material into the cavity via the second gate opening.

The present invention relates to an FPC connector housing, more particular to a DDRS connector housing. The invention also relates to a method for producing the connector housing as well as to a cavity mold suitable for the production of the connector housing. The cavity mold comprises a double gating system with centrally positioned injection gates. The connector housing can be used in a connector for mounting on a flexible printed circuit (FPC) assembled in various kinds of electrical and/or electronic devices.

Provided are an inner part and a resin molded article according to which it is possible to mitigate the concentration of stress at a distal end of a melt rib. An inner part, around which an outer portion is to be arranged through integral molding, includes a main body portion made of resin, and a melt rib provided protruding outward from the main body portion. The melt rib is formed such that a height of the melt rib is greater than a thickness of the melt rib, the thickness decreases from the main body portion to a distal end of the melt rib, and the melt rib includes a melting portion configured to partially melt during molding of the outer portion.
