An injection molding device for fabricating a part, the device including an injection mold, the mold being formed of a support and a countermold that are distinct and that define between them a mold cavity presenting a first shape; and at least one injection device for injecting a fluid material into the mold cavity; the device including deformation elements configured to modify the shape of the mold cavity into a second shape distinct from the first shape.

Presented are manufacturing control systems for fabricating composite-material structures, methods for making/operating such systems, and resin transfer molding techniques for ameliorating race-tracking effects in fiber-reinforced polymer panels. A method for forming a composite-material construction includes confirming, via a system electronic control unit (ECU), that a fiber-based preform is placed in a mold cavity and that opposing mold segments of the molding apparatus are sealed together. A filler, such as a compressible bladder, a cluster of spring-biased pins, or a spray-chopped fiber bed, is introduced into a void between the fiber-based preform and a tool face of one mold segment to thereby eliminate an unwanted resin race track. The system ECU commands a resin pump to inject resin through a primary gate of the molding apparatus and into the mold cavity to thereby impregnate the fiber-based preform with the resin. One or more vents operate to evacuate air from the mold.

Aircraft that incorporates a rounded-hat composite stringer connected to an inner side of the skin of the aircraft to form an elongate conduit that defines a conduit axis, where the conduit axis includes at least one curving portion. The rounded-hat composite stringer can be manufactured by constructing a lower forming die and an upper forming die, each forming die having a length and defining a curve along at least a portion of the length of the die, cutting a pre-cured flat composite charge dimensioned to form the rounded-hat composite stringer, pressing the flat composite charge between the lower and upper forming dies to shape the composite charge into a pre-formed stringer having an inner side between curved fillet portions, contacting a forming member against the inner side of the pre-formed stringer, applying radius fillers to the curved fillet portions of the pre-formed stringer, curing the pre-formed stringer, and removing the forming member from the cured stringer.

An injection station of an injection blow molding machine. The injection station comprises a lower die plate and an upper die plate, with lower and upper die plates being shiftable relative to one another between an open position and a closed position. The injection station additionally includes one or more lower mold halves rigidly secured to the lower die plate. The injection station additionally includes one or more upper mold halves floatingly secured to the upper die plate such that positions of the upper mold halves are configured to be adjusted with respect to the upper die plate. Each of the lower mold halves corresponds with an upper mold half to present one or more mold cavities when the lower and upper die plates are in the closed position.

The application relates to an adjustable moulding tool and corresponding model production method, including following process steps: moving rods towards the said chamber through the said chamber's holey surfaces manually or via mechanisms in increments numbers of which are calculated through computer programs or manually, after the formation of the emptiness in the shape of the model, pouring of the material in a manner to fill the emptiness, heating and cooling or applying other processes in accordance with the characteristic of the poured material to enable that material takes the desired monolithic shape, after material takes the form of the model monolithically, making the casting chamber free of the rods, which have initially been moved towards the casting chamber with the purpose of the formation of the emptiness, by moving the rods in the reverse directions and taking out the produced model through an openable surface of the said chamber.

A system and method is provided for manufacturing a composite structure. In an exemplary aspect, the system includes multiple flexible tooling plates that are interlocked to each other to form a tooling surface for forming a composite structure to be manufactured. Moreover, the system includes an actuator array connected to the flexible plates and that can move the flexible plates relative to each other to adjust a contour of the tooling surface to correspond to a design contour of the composite structure to be manufactured.

A manufacturing apparatus includes an arm main body with a long tubular or columnar shape having a uniform lateral cross-section, and attachment interface parts fixed to both sides of the arm main body and attached to another member. The apparatus includes: a pair of fixing parts supporting a part of each of the attachment interface parts and each end of the arm main body and each including a material filling space at least near a joint part between each of the attachment interface parts and the arm main body; a slide mechanism capable of adjusting a distance between the two fixing parts along a longitudinal axis of the arm main body by moving at least one of the fixing parts; and a material injection part injecting a molten material into the space so as to joint each of the attachment interface parts to each end of the arm main body.

A method for manufacturing first and second trim parts of a vehicle, the first trim part having a first thickness and the second trim part having a second thickness different from the first thickness. The method includes introducing the first trim part and the second trim part between a front and a back tool of the forming mold, the front tool having a front fixed part and a front movable insert movable with respect to the front fixed part along a main direction, the back tool having a back fixed part and a back movable insert movable with respect to the back fixed part along the main direction; and adjusting settings of the forming mold to different values for the first and second trim parts.

The composite structure forming system comprises a plurality of charge forming stations and a plurality of conveyor systems. The plurality of charge forming stations is configured to operate in parallel, each charge forming station of the plurality of charge forming stations is configured to form a respective composite charge of the contoured elongate composite structure. Each conveyor system of the plurality of conveyor systems is configured to transport a respective composite charge through a respective charge forming station.

Integrally molded insulated concrete form skeleton modules are discussed, along with various other insulated concrete form skeletons and related methods and technologies. Insulated concrete corner forms are discussed, and ways to make same are also discussed. One or both folding and cutting steps may be used to create a corner form from a planar form, or from two independent concrete forms.
