Methods and systems for creating cold plates are disclosed. For example, in one example method for manufacturing a cold plate made of a thermally-conductive plastic includes performing a first injection-molding process using the thermally-conductive plastic to produce a first unitary body, the first unitary body including one or more elongated sections forming a unitary body, performing a second injection-molding process using the thermally-conductive plastic to produce a second unitary body, the second unitary body incorporating the first unitary body so as to cover a majority of the first unitary body and form a respective coolant pipe body corresponding to each elongated section, and performing a machining process on the second unitary body so as to create a conduit in each respective coolant pipe body suitable for a fluid to pass through to create respective coolant pipes.

The invention relates to a method for manufacturing a composite aircraft window frame; the method comprises the steps of: a) positioning in a mold a preform made of pre-impregnated material including dispersed fibers, with a predefined orientation, in a thermosetting resin matrix; b) closing the mold so as to define a gap between at least one surface of said preform and a portion of said mold; c) injecting thermosetting resin into the closed mold through an inlet opening of the mold itself, so as to fill the gap and completely lap said surface of the preform; and d) applying a uniform hydrostatic pressure on the surface by the injection of the resin.

A method for the design, manufacture, and assembly of modular lattice structures composed of cuboctahedron unit cells.

An injection mold for producing a sprinkler head part and related injection molding methods are described. The sprinkler head part includes a first, second, third and fourth mold portions. The first and second mold portions include first and second shaping elements structured to cooperatively form a body including a substantially cylindrical portion and a substantially planar portion, and two frame arms extending from the substantially planar portion of the body. The third mold portion includes a shaping element structured to form an orifice in the body of the sprinkler head. The fourth mold portion includes a shaping element structured to form a cross member connecting the two frame arms. The injection methods include injecting a composite material in molten form into the mold to form the molded sprinkler head part. The composite material includes thermoplastic polymeric resin and a plurality of reinforcing fibers dispersed in the resin.

A closure (1) with a shell (2) for securement to a container neck (11) and a lid (3) pivotally connected to the shell (2) by a pair of hinge elements (6). A hinge line (50) in the side wall (5) delineates a deformable latch (8) having an external grip tab (80) and an internal 5 engaging tab (82) between the grip tab (80) and a top wall (4) of the lid (3). The grip tab (80) extends radially from a side wall (5) of the lid (3) and the engaging tab (82) engages a lip (13) surrounding the mouth of the container neck (11). The deformable latch (8) is configured to deform along the hinge line (50) when an opening force is applied to the grip tab (80), thereby to disengage the engaging tab (82) from the lip (13) of the container neck 10 (11).

An index plate molding device configured to produce a multi-component part including an injection mold having an injection parting surface, and an ejection mold having an ejection parting surface in selective contact with the injection parting surface to form an ejection parting line therebetween. The index plate molding device also includes an index plate movable relative to the injection mold and the ejection mold, where the index plate includes an index parting surface in selective contact with the injection parting surface to form an index parting line therebetween, and where the index plate is shaped such that the outer surface of the first component of the multi-component part is available for overmolding on both sides of the index parting line when the first component is coupled to the index plate.

By using a forming die having a fixed die and a movable die moving along a parting surface on the fixed die and by moving the movable die along the parting surface, to press and hold a sintered part between the movable die and the fixed die, to form a cavity around the sintered part except parts which abut on the fixed die and the movable die by the forming die, and to fill the cavity with melted material which becomes an exterior part, so that the sintered part and the exterior part are integrated by insert molding.
