The invention relates to a resin injection regulator for a resin injection circuit in a mould for producing a composite part, in particular a turbine engine composite part, characterised in that it comprises at least one vessel which is connected to said circuit and inside of which a movable wall means can be moved in a sealed manner, said movable wall means defining in said vessel a first cavity which forms a container for accumulation of resin and is designed to be connected to at least one part of said circuit, and a second cavity which is designed to be connected to a source of pressurised fluid, said movable wall means being designed to be urged by the pressurised fluid with which the second cavity is supplied in order to exert a pressure on the resin contained in the first cavity by isolating said resin from said fluid.

A method is provided for configuring fluid in a programable fluid array which includes applying a sequence of magnetic fields to a movable fluidic network component; which includes a magnetic object to produce a force on the component. In one arrangement the fluid array includes a plurality of pre-formed channels and at least one property of at least one of said pre-formed channels is changed by the movable fluidic network component in another arrangement the fluid array comprises an injection molding system where the programmable fluid array is used to improve the speed and accuracy of the injection molding process and/or to additionally modify the shape and form of a molded object. In this arrangement the fluidic network component follows a path through the mold cavity determined at least in part by a sequence of magnetic fields and exerts a force on molding material therein.

Provided is a glue injection device, comprising: a glue melting unit (400), the glue melting unit (400) comprising a rotatable turntable (402) and a fixing member (403), wherein a feeding groove is provided on the surface of the turntable (402) facing the fixing member (403) and the turntable (402) melts the raw material in the feeding groove into glue when rotating with respect to the fixing member (403); and a glue injection unit (500) connected with the glue melting unit (400). The glue is injected into the glue injection unit (500) when the turntable (402) is rotated, and the glue injection unit (500) is capable of injecting the glue therein into a mold.

A system forms, at an end of a multifiber ribbon cable, a multifiber ribbon cable segment having an enlarged core-to-core spacing. A UV-transparent mold is mounted on top of a chassis. The mold defines a plurality of individual fiber channels corresponding to individual fibers of the existing multifiber ribbon cable and having a spacing equal to that of the enlarged core-to-core spacing. Each individual fiber channel passes through the internal cavity. The assembled mold further includes an injection system for receiving light curable, flowable material from the reservoir and pumping system and feeding it into the internal cavity, and at least one vent for allowing air to escape from the internal cavity as the light-curable, flowable material is fed into the internal cavity. The injected material is cured by exposure to a curing light.

An injection molding apparatus has a mold tool that is positioned around a field joint of a pipeline to define a mold cavity. Two or more pumping chambers communicate with the mold tool. Each chamber is expansible to draw in molten polymer and contractible to drive the polymer into the mold cavity. Expansion of one chamber is synchronized with contraction of another chamber. The operation of supply and injection valves associated with the chambers is also synchronized, both with each other and with expansion and contraction of the chambers. In the embodiment described, two pumping chambers are defined within a common pressurizing cylinder, in which the chambers are separated by a piston. The piston is movable within the cylinder to determine and to synchronize expansion and contraction of the chambers.

A supercritical fluid microcellular injection molding method includes the following steps. Preheating: the feed pipe is preheated to a hot melt temperature of polymer. Feeding: the polymer is poured into the hopper and enters the feed pipe. A metering screw is rotatably received in the feed pipe for forwardly pushing the hot molten polymer when being rotated. Injecting SCF: the SCF is injected into the feed pipe and mixed with the hot molten polymer into a homogeneous monophasic fluid. Quantitative discharge and depressurization: the monophasic fluid flows across a first gear pump and a second gear pump mounted on the front end of the feed pipe. Discharging and molding: the monophasic fluid actuated by the first gear pump and the second gear pump is injected and molded by the die head fixed to the discharge end of the second gear pump.
