A fiber composite resin molding made of fiber composite resin including fibers and base resin, wherein fiber orientation directions of the fibers in a thickness direction of the fiber composite resin molding are different between a discretionary first region and a second region away from the first region on the surface of the fiber composite resin molding.

The disclosure is directed to an injection molding device comprising at least one injection mold with a first and second mold half during operation being displaceable with respect to each other in a first direction (z) between a closed position and an open position. The first and second mold halves forming in the closed position at least one cavity therebetween for receiving melted plastic material from an injection nozzle. The at least one cavity comprises first and second cavity sections which are by a constriction. Melted plastic material is injected into the first cavity section and travels from there via the constriction into the second cavity section. A first sensor arrangement is arranged in a cavity wall of the first cavity section and a second sensor arrangement is arranged in a cavity wall of the second cavity section to determine relevant parameters in relation to the constriction.

To provide a method for manufacturing an interdental cleaning tool that can prevent deformation of a core base at molding of a cleaning flexible part using an elastomer material, thereby effectively preventing occurrence of molding failure of the cleaning flexible part.

The method in the present invention includes: a base part molding step of providing first metal molds 30 and 31 for molding base parts with a plurality of first molding spaces 32 aligned in parallel and including core base molding sections 32a and handle base molding sections 32b, providing the first metal molds 30 and 31 with connection part molding sections 35 to communicate with the adjacent handle base molding sections 32b, and supplying a synthetic resin material with a fiber material at a time to the plurality of first molding spaces 32 from gates 34 to form a plurality of base parts at a time; and a flexible part molding step of setting the core bases of the base parts into second metal molds, holding the core bases at two or more longitudinal portions by a plurality of pairs of hold pins in the second metal molds, each pair including two pins, and charging an elastomer material into the cleaning flexible part molding spaces.

To provide a vehicle exterior decorating member capable of providing a sufficient gradation effect to an observer, and having enhanced design characteristics, and to provide a method for manufacturing the same.

A vehicle exterior decorating member includes a base member made of a colored translucent body having a front surface and a back surface including a surface having unevenness, and a light non-transmissive layer formed on a back surface side of the base member. The base member includes a general portion where a thickness is constant at greater than or equal to 2.5 mm and smaller than or equal to 4.0 mm, and a gradually changing portion where a thickness gradually changes. The gradually changing portion includes a maximum deviation portion where a difference in thickness between the general portion and the gradually changing portion becomes a maximum, and has (A) and/or (B). (A) Difference between a visible light transmissivity at the maximum deviation portion and a visible light transmissivity at the general portion is greater than or equal to 5%. (B) Assuming an L value of a Lab color system defined in JIS Z 8729, a difference between an L value at the maximum deviation portion and an L value at the general portion is greater than or equal to two.
