Midsole for an article of footwear formed from preforms and method for manufacturing same
A midsole and a method of manufacturing it includes placing first and second preforms into a midsole recess of a mold, with first and second portions of the mold defining a first overflow chamber connected to the first recess; closing the mold by positioning the first and second portions in contact with one another; heating the mold for a predetermined period of time at a predetermined temperature such that the first and second preforms melt and bond together to form a midsole, with a portion of each of the first and second preforms flowing into the first overflow chamber to form a first overflow portion; removing the midsole from the mold; allowing the midsole to expand; and cutting away the first overflow portion.
METHOD FOR PRODUCING A STRUCTURAL COMPONENT
A method is specified for producing a structural component, in particular for an aircraft, ground vehicle, or watercraft, or for a rotor blade of a wind turbine, in which method an arrangement of fibers and plastic material is laid in a mold and subjected to an increased pressure and an increased temperature, wherein a mold is used which comprises at least one recess in which a reinforcing element is arranged. The object is to be able to cost-effectively produce a structural component of this type. For this purpose, it is provided that the reinforcing element is laid in the recess together with a core, wherein a differential volume between the recess and core, at least in a predetermined region, is chosen such that it is smaller than a segment of the reinforcing element arranged in said region by a predetermined amount.
METHOD FOR PRODUCING FOAM MOLDED PRODUCT AND MOLDING MOLD
The present invention relates to a method for producing a foam molded product, in which in a foaming step, at least a part of a burr is made to be an undercut that is caught in a movable mold portion when mold opening the movable mold portion, in a cross section obtained by cutting a foam intermediate on a plane orthogonal to a direction in which a boundary between a main body and a burr extends, a fragile portion is provided at the boundary such that at least a part of the burr located near the boundary is narrowed toward the boundary, and a foam intermediate is formed, and in a removal step, the fragile portion is broken and the burr is removed by pulling the burr with the movable mold portion.
CURING MOLD FOR MANUFACTURING A TURBOMACHINE COMPONENT MADE OF COMPOSITE MATERIAL FROM A PREFORM AND METHOD FOR PRODUCING A COMPONENT BY MEANS OF SUCH A MOLD
A curing mold for manufacturing a turbomachine component is made of composite material from a preform, including: a first and a second body defining an air gap receiving the preform; at least one primary channel arranged in the first and/or the second body; an injection member of a pressurized fluid in the primary channels; at least one secondary channel, in which a piston slides, which delimits, on the one hand, a first chamber in communication with the or a primary channel and, on the other hand, a second chamber in communication with the air gap, and which is designed to compress thermosetting resin which has entered the second chamber from the preform in the air gap, so as to put the preform under hydrostatic pressure.
MIDSOLE FOR AN ARTICLE OF FOOTWEAR FORMED FROM PREFORMS AND METHOD FOR MANUFACTURING SAME
A midsole and a method of manufacturing it includes placing first and second preforms into a midsole recess of a mold, with first and second portions of the mold defining a first overflow chamber connected to the first recess; closing the mold by positioning the first and second portions in contact with one another; heating the mold for a predetermined period of time at a predetermined temperature such that the first and second preforms melt and bond together to form a midsole, with a portion of each of the first and second preforms flowing into the first overflow chamber to form a first overflow portion; removing the midsole from the mold; allowing the midsole to expand; and cutting away the first overflow portion.

MOLD HAVING A SPRUE CUTTER
The invention relates to a mold (200) for producing a foam cladding (120) made of plastic on a planar component (100) or for producing a foamed plastic part (120), comprising a mixing head (300) for producing liquid plastic from at least two components, at least one first cavity (240) for receiving the plastic in order to form the foam cladding (120) or to produce the foamed plastic part (120), a sprue channel (210) for connecting the mixing head (300) to the at least one first cavity (240), and a further cavity (220), which is formed at the transition of the sprue channel (210) to the first cavity (240) and widens the sprue channel (210). For automated cutting of a tag-like sprue, which would otherwise adhere to the foam cladding, the invention provides that a sprue cutter (400) having at least one slide (410) is movably mounted on the mold (200), which slide can be moved by means of at least one actuating cylinder (450) in the direction of the sprue channel (210) toward the first cavity (240) and, in an end position of the movement of the slide, closes off the first cavity (240) from the sprue channel (210) and/or from the further cavity (220) by means of at least one edge (414) and/or contour (412).
METHOD AND TOOL FOR MANUFACTURING A COMPOSITE AIRCRAFT WINDOW FRAME
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.
Method of manufacturing gasket
A process for producing gaskets by curing a liquid molding material applied over a plate by a dispenser, wherein in order to improve accuracy in the cross-sectional shape and/or height of the gaskets, the process comprises the steps of: using a dispenser to coat the upper surface of a plate with a liquid molding material, and form a coating layer extending endlessly in a prescribed pattern; and overlapping a molding jig on the plate, the molding jig having in a lower surface a molding groove extending endlessly in a prescribed pattern corresponding to the coating layer, correcting the cross-sectional shape of the coating layer to a cross-sectional shape that corresponds to the molding groove, and curing the coating layer.
Mould arrangement and method for compression moulding fiber reinforced preforms
A modified compression moulding arrangement where the compression moulding tool has been modified to allow for the use of pre-impregnated pre-form sheets in order to produce class A automotive structural parts in high volume. The pre-impregnated pre-form has continuous un-chopped fibers that extend across an entire length of the pre-impregnated pre-form. The pre-impregnated pre-form is then placed in an open compression moulding tool that has a bottom half and a top half that are movable between an open position and a closed position. When the mould tool is in the closed position, the top half and bottom half create a forming cavity that is defined by a forming surface of the top half and a forming surface of the bottom half. The forming surface of the bottom half has a boundary defined by a run-off edge and an upshear that is necessary for forming a class A structural automotive component using pre-impregnated pre-form material.
