A structural component serves as a container for a vehicle. The structural component comprises a trough-shaped container section, an edge region, and fastening elements that are provided in the edge region. The container section forms a compartment and defines a bottom region and two or more wall regions, which are at least sectionally inclined with respect to the bottom region. The two or more wall regions are arranged between the bottom region and the edge region. The fastening elements are arranged and distributed around the container section. The container section and the edge region are formed of an injection moldable fiber reinforced thermoplastic material. The structural component at least sectionally has a porous internal structure that is formed by foaming the thermoplastic material.

A molding apparatus includes a mold comprising a stationary outer mold with a substantially tubular mold cavity, a moveable end mold with an end mold cavity alignable with the tubular mold cavity, and a stationary elongated mold core with a fluid channel therethrough, the mold core extending through the tubular cavity into the end mold cavity. A method of using the apparatus includes injecting a molding material at a material flow rate into the mold, moving the end mold at a speed in a linear direction from a first position to a second position, supplying a fluid at a fluid flow rate to the fluid channel, and varying at least one of the material flow rate, the end mold speed and the fluid flow rate as the end mold moves from the first position to the second position.

A method for producing a three-dimensionally shaped trim part of a motor vehicle, which has a visible side and a mounting side. A flowable material is injected with pressure into a chamber of an injection molding tool, which has at least two mold shells, which, when assembled, form the chamber with a negative mold of the trim part, wherein at least one first of the mold shells forms the visible side and at least one second of the mold shells forms the mounting side of the trim part. The material is hardened in the chamber. A gas pressure is generated that acts in a planar manner between the second mold shell and the material during the hardening. The hardened material is removed as a trim part from the chamber of the injection molding tool.

A mold for resin injection molding 1 having a shaping region formed by a low-density shaped portion 22 and a high-density shaped portion 21 in which each ventilation channel 32 for gas existing between an external region and a molding portion region forms a hollow state surrounded by a peripheral wall having any one or both of the high-density shaped portion 21 and the low-density shaped portion 22, and the secondary vent 33 connecting communicatively with a region molding portion is formed only by a low-density shaped portion 22 with thickness thinner than that of the shaping region.

The present invention provides a method for producing a durable semispherical shoe which can be prevented from being subjected to seizure even in a dry lubrication state in which there is no lubricating oil at a start time of an operation of a swash plate compressor, can be restrained from deteriorating in its lubricating property due to generated frictional heat, and can be restrained from deteriorating in its strength at a production time and an injection molding die. A semispherical shoe (4), for a swash plate compressor, to be produced by the production method has a base material (5), consisting of a hard material, which has a hollow part along a central axis thereof and a resin layer, consisting of a resin composition, which is formed on a surface of a planar part, disposed on a periphery of the base member, which is to be subjected to sliding contact with the swash plate and on a surface of a spherical part, disposed on the periphery thereof, which is to be subjected to sliding contact with a piston. A resin-filled portion (8) where the resin composition is filled and an empty portion where the resin composition is not filled are formed in the hollow part of the base material. The resin-filled portion (8) and the resin layer are formed by injecting and filling the resin composition into a portion to be formed as the resin-filled portion (8) with the base material (5) being disposed inside a cavity (22) of the injection molding die.

An injection molded article obtained by injection molding a thermoplastic resin composition comprising 100 parts by mass of a thermoplastic resin and 50 parts by mass or less of at least one of a filler and a colored metallic pigment, wherein at least one weld exists, and a long diameter of 95% by mass or more of the filler existing within a cross-sectional depth of 50 μm or less from a surface of the weld is parallel to the surface of the weld.

A holding portion having a diameter larger than that of a cavity is formed in communication with the cavity, in an area of a two-part type mold, the area including a portion corresponding to an annular groove. Subsequently, an insert member formed in a cylindrical shape and provided with, on an outer circumferential surface, the annular groove having no step in a groove surface is fitted to the holding portion, and then the mold is closed. On an inner circumferential surface of the insert member, a surface treatment layer having a surface roughness rougher than those of other portions of the insert member is formed. Molten resin is injected into the cavity; thereafter, an assist material is injected into the cavity to mold the resin into a desired pipe body. Then, the insert member and the pipe body are integrated along with curing of the resin.

An additive injection system for use in injection molding machines to inject additive materials, such as fluids or powders, downstream of a nozzle of the injection molding machine. The additive injection unit has an additive tank to store or contain additive material and additive injectors that inject an additive material into an injection molding machine. A pump pumps the additive material from the tank through a common manifold connected to the additive injectors to be injected into the injection molding machine. A controller controls operation of the additive injection device and one or more sensors coupled to the additive injection device can provide feedback to the controller.
