摘要:
A press is described (10) for the production of panels, comprising an upper half-form (16) and a lower half-mould (18) made to receive a mould by which the panels are made, the half-moulds having a deformable structure for obtaining non-plane panels. To be able to obtain panels of any shape, said structure consists of flat segments (22a-22h) hinged between each other two by two and each equipped with motor means (30, 31 ) for rotating the respective segment with respect to, and independently from, the adjacent segment.
摘要:
Methods for fabricating and manufacturing solid solution perforators (SSPs) using sharp metal or glass needles and/or subsequent molding and use are described. The methods entail making microneedles by various precision machining techniques and micromold structures from curable materials. Various designs of patch, cartridge and applicator are described. Also described are methods for adjusting the microneedle mechanical strength using formulation and/or post-drying processes.

A mould is disclosed comprising: at least one malleable mould member for defining a mould surface; and a plurality of actuators for forming said mould member into a pre-determined shape.
摘要:
The preform is formed by an upper neck which maintains unchanged its form in the final object and a hollow body, joined to the neck. The method foresees the insertion, within a matrix cavity, of a metered body of polymeric material whose mass is metered according to a reference value, and the subsequent pressure insertion of a punch within the matrix cavity until it closes the mold’s molding chamber, the punch conferring the shape to the inner surface of the preform and the matrix having an inner surface which confers the shape to the outer surface of the preform. According to the invention, in the molding of the preform, the error of the mass of the metered body with respect to the reference value is distributed in the hollow body, which undergoes a subsequent hot deformation until it achieves the final shape. In the mold, the matrix comprises at least one deformable wall (31) whose inner surface defines at least part of the inner surface of the matrix part intended to give form to the hollow body of the preform, said deformable wall (31) having, at least in part, a relatively thin thickness which permits it to be elastically deformed under the pressure of the polymeric material in the final preform molding step, thereby varying the thickness of the hollow body.
摘要:
The present invention makes use of loose fibrous material (for instance, chopped fibers) as reinforcement matrix material in the manufacture of carbon-carbon composites. In accordance with this invention, a constraint fixture is provided which can be separated from the mold. The constraint fixture has an internal shape corresponding to the shape of a desired preform component, with the internal shape being defined by a bottom plate (2), an annular ejector plate (3, 3'), a inner wall (10), an outer wall (4), and an annular top plate (11, 11'). The constraint fixture is normally made of metal, porous ceramic, or carbon material. The constraint fixture of the mold holds the loose matrix materials (fibers, along with any fillers and/or additives). The mold assembly itself is segmented, so that the constraint- fixture and the loose fill materials in the fixture can be removed and subjected to further processing as a unit. Such further processing may include Chemical Vapor Deposition or resin or pitch infiltration or Resin Transfer Molding. The preform matrix may remain in the constraint fixture through such processing steps as densification and until it is removed therefrom for final machining.
摘要:
The invention relates to a method for the continuos manufacturing of curved insulating panels, wherein an upper strip (4) and a lower strip (5) of sheet metal, between which insulating material is interposed, are introduced into a mould (30) having a curved configuration according to that of the panels to be produced; advantageously, at least one of the strips (4, 5) is bent upstream of the mould (30) and introduced therein without discontinuity in its curvature. The invention also comprises an apparatus for carrying out the method, wherein a mould (30) is provided, which has variable configuration so as to produce panels of different curvature.
摘要:
Method of high-strength sandwich skin fabrication uses the thickness of a high-density foam skin core (27) to mask minor imperfections on the surface of the mold, thereby allowing the mold (10, 20) to be divided into separate integral parts that have the capacity to be moved, then fixed and set, so as to describe different curves or modify dimensions of the board. Mold is reversible; male/female configurations permit fabrication of a wide array of custom designs. Method offers low production costs due to a rapid mold cycle, reduced labor, and efficient use of space, yet produces an exceptionally high strength, light weight board because of the increased shear strength of the monocoque perimeter rail (70), and the optimum fiber/resin ratio in the cored, structural sandwich skin.
