摘要： A method of manufacturing a complex-shaped composite part, including the steps of applying a metallic sheath around a composite laminate workpiece and applying an electric current through the metallic sheath to heat the workpiece. The metallic sheath may be sealed around the composite laminate workpiece, with air or atmosphere evacuated therefrom. The method also includes shaping the workpiece in the metallic sheath into a complex-shaped composite part while it is being heated. The shaping can be performed between two ceramic dies or using other techniques for forming complex shapes and curvatures into the workpiece. The method then may include cooling the complex-shaped composite part and removing the metallic sheath from the complex-shaped composite part. This method minimizes cycle times and reduces breakage of fiber reinforcement of the composite laminate. The method also helps avoid tearing, buckling, or wrinkling of the workpiece during formation via the structural support provided.

摘要： A component is formed by welding a plurality of sheets of metal to form a blank with a number of weld nuggets, placing the blank between a die section and a lid section, heating the die section to heat the blank, and introducing a pressurized gas between the lid section and the die section to press the blank into a mold in the die section to form a component. The weld nugget (1302) elongates between about 1 percent and 25 percent less than other portions (1304, 1306) of the blank (1300) during the forming of the titanium sructure.

摘要： The invention is directed to a system and method of applying a coating of lubricant material to the surface of a sheet metal blank in a controlled manner such that some areas of the blank have uniform thickness of lubricant while other areas have no lubricant at all or have a variable amount (progressively increasing or decreasing) of lubricant. This is achieved through the use of a mask template that comprises an overspray fence and at least one contact element. The lubricated coated sheet metal blank is utile for superplastic forming to produce specialized complex shaped parts. The invention advantageously lessens the possibility of skid or slip lines appearing in the finished product as well as lessens the likely build-up of lubricant in forming dies—easing maintenance requirements.

摘要： A method of producing composite or bonded metal components comprises the steps of:
applying melted resin on a surface of a mould (121), the resin solidifying upon contacting and cooling on the mould surface to thereby form a layer of solidified resin on the mould surface;
laying a composite or bonded metal lay up (159) over the resultant layer of solidified resin on the mould surface;
locating the mould (121) together with the lay-up (159) under a pressure chamber (151) having an elastically deformable chamber wall;
circulating a fluid at an elevated pressure and temperature through the pressure chamber (151) to heat and melt the solidified resin and allow the resin to impregnate the lay up (159) such that the composite or bonded metal lay-up is compressed and cured or formed.

摘要： A separating disk (20) for a disk package (19) of a centrifuge rotor (5) has a tapering shape and extend around an axis (x) of rotation, and along a rotary symmetric surface. The separating disk is configured in such a way that it creates an interspace between the separating disk and an adjacent separating disk in the disk package, and comprises first protrusions (31) extending outwardly from the rotary symmetric surface and second protrusions (32) extending inwardly from the rotary symmetric surface. Each first and second protrusion defines a contact zone adapted to abut the adjacent separating disk. The contact zone of the first protrusions is displaced in relation to the contact zone of the second protrusions. The first and second protrusions are provided after each other in the peripheral direction of the separating disk. The tapering shape and the protrusions of the separating disks have been provided though pressing of a blank of a material against a tool part having a shape corresponding to the tapering shape of the protrusions of the pressed separating disk.

摘要： A apparatus for forming a three-dimensional (3D) object from a sheet material preferably includes a sheet material, a shaping die defining a cavity adapted to receive at least a portion of the sheet material, a portion of the cavity having a shape corresponding to a desired surface of the 3D object, and a forming member positioned relative to the sheet material opposite the cavity and having a rigid edge having a shape corresponding to a desired small-radii event of the 3D object. When force is applied to the sheet material and to the forming member, the sheet material is forced against the portion of the cavity to form the desired surface, and the rigid edge is forced against the sheet material to form the desired small-radii event. A method of using the apparatus for spline bending of sheet material is also disclosed.
