Abstract:
A mold insert and an injection-molding machine including the mold insert. The mold insert has at least one filament cavity and a stack of at least a first and second insert plates, wherein the first plate has a front face that closely abuts a front face of the second insert plate. A portion of the a filament cavity is provided in at least one of the front faces of the first and second insert plates such that the filament cavity is open at a top surface of the mold insert but does not extend to a bottom surface of the mold insert. A venting cavity is provided in the same front face of the insert plate in which the portion of the at least one filament cavity is provided.
Abstract:
A method of curing spokes is provided in which first molds of a first and second series of molds are placed into a platen press, and force and heat applied. The platen press is opened and the first mold of the first series is moved relative to the platen press while the position of the first mold of the second series is kept the same relative to the platen press. Force and heat are applied to the molds. The platen press is opened, and the first mold of the first series is removed while the second mold of the first series is kept within the platen press. A cured spoke is removed from the first mold of the first series.
Abstract:
A template manufacturing method includes preparing a structure including a first substrate and a stacked body that is provided on the first substrate, the stacked body including a first lower layer including a first material, a first upper layer provided on the first lower layer including a second material different from the first material, and a first cover layer provided on a first cover region of the first upper layer and including a third material different from the second material. The method further includes forming a first resist layer on a portion of the first cover layer and on a first portion of the first upper layer, and exposing a second portion of the upper layer. The method yet further includes removing the second portion of the first upper layer using the first cover layer and the first resist layer as a mask.
Abstract:
A tangible structure includes a set of removable and parallel rods, each rod including a head; a set of drive devices, each drive device including a motor element generating a rotational motion to a transverse shaft to transmit a translational motion to a rod, the drive device being piloted in order to transmit a motion to the rod at a given speed and in a given direction; a holding system for the drive devices making the drive devices integral with each other, and a calculator determining a set of pilot set points, each pilot set point being transmitted to a drive device on the basis of a first digital set point.
Abstract:
A mold for use in fabricating a gas turbine fan casing out of composite material includes a mandrel for having wound thereon a fiber preform of a fan casing and an annular wall with an outside surface of profile corresponding to the profile of the inside surface of the casing that is to be fabricated and of two lateral rims of profiles corresponding to the profiles of outer flanges of the casing that is to be fabricated; a plurality of mold cover angular sectors that are assembled in leaktight manner on the mandrel and that are to close the mold and to compact the fiber preform wound on the mandrel; and a plurality of locking keys configured to lock together in leaktight manner neighboring mold cover sectors. A method of closing such a mold, and a method of fabricating a fan casing are included.
Abstract:
A Method for manufacturing molding elements for molds is provided herein. The molds are used for molding tires provided with a tread with a circumferential arrangement of tread pattern elements. The method includes: a step consisting in aligning a plurality of basic linings; a step consisting in generating, from the basic tread circumference portion, an intermediate support; and obtaining an unfinished molding element from the intermediate support.
Abstract:
The invention relates to a mold for producing three-dimensional items, consisting of at least two mutually attachable pieces, and within which pieces the volume of the item to be produced is delimited. In said mold, owing to the mutually supporting surfaces, said pieces have formations delimiting airtight chambers between consecutively attached pieces. At least one of the pieces used to form part of each airtight chamber has a pneumatic valve through which said chambers are connected to a vacuum source, by means of which a sufficient negative pressure is created in the chambers to fix to one another the pieces delimiting such chambers. The walls of the pieces are non-deformable as a result of the negative pressure created within the chambers.
Abstract:
Embodiments of the invention relate to injection mold components, assemblies, and molding system that include superhard materials. Such injection mold components, assemblies, and systems may decrease wear of certain injection mold components, which may result in improved productivity of the injection mold and molding systems that utilize such components.
Abstract:
A cylindrical case includes a case main body, and a groove disposed annularly at one end of the case main body. A peripheral wall of the case main body is formed by alternately laminating a biaxial fabric layer, which includes a biaxial fabric of a non-crimp structure composed of reinforcing fiber bands having an orientation angle of ±45°, and a roving layer. A groove wall of the groove is formed by alternately laminating the biaxial fabric layer, which continues to the case main body side, and a triaxial fabric layer, which includes a triaxial fabric of a non-crimp structure composed of reinforcing fiber bands having an orientation angle of ±45° and a reinforcing fiber band having an orientation angle of 0°.
Abstract:
A shaping or forming apparatus, comprising a plurality of members, means to selectively lock the rows in a set position with a force greater than that used to position unlocked members, and means to selectively position members relative to each other in more than three different positions.A non definitive list of practical applications comprise at least one of: form, deform, shape, cast, mold, haptic output, visual output, control of material flow, control of force.
