摘要： The present invention relates to molds and mold portions that comprise or have integrated therewith a resinous material and comprise at least one electromagnetic actuator imbedded in the resinous material, so as to be capable of further forming the at least one precursor area of the work piece. The resin is used to locate the coil, and clamps or other restraints preferably are used to keep the weaker electrically insulating resin out of a state of large tensile stress or strain, which may cause it to fracture. Preferably, the resinous material comprises metallic flakes imbedded therein.

摘要： One of the key features of the present invention is the use of a electrical conduit arrangement that allows for the tailoring of the magnetic field so as to provide for the greater amount of force to be brought to bear generally in the center of the work force area. The present invention provides for such capability by providing for a single central current conduit for forming longitudinally extending work pieces. The present invention also provides for the splitting, and/or direction (or curvature) reversal, of the electrical current pulse one or more times to likewise tailor the magnetic field of the work-coil or forming actuator.

摘要： Methods and devices provide for high velocity forming of medical device casings. The high velocity forming may be produced by creating a pressure wave within a liquid contained by an enclosure. A die and a workpiece adjacent to the die are in the path of the pressure wave within the enclosure and the pressure wave forces the workpiece to conform to the contours of the die. Objects may be adhered to the die to provide for customized contours. Trimming features may be included within the enclosure to trim excess material from a formed workpiece as an integral part of the forming process. Various other features may also be provided within the enclosure including a diffuser to disperse the pressure wave. The workpiece may be of various forms including flat sheet stock.

摘要： A laser, aimed at a flyer plate tab, causes optical energy to be directed at the tab, specifically, at a top surface thereof. Energy impacting the tab accelerates the tab out of an initial bent position, straightening it into an impact with a target sheet. The impact occurs in excess of 100 m/s, resulting in a metallurgical bond between the tab and the target sheet. The laser preferably strikes the top surface in a normal direction, based upon an initial angularity of the tab relative to the target. The laser emission, preferably in the range of 1 to 100 Joules delivered in a microsecond, may be augmented by an ablative layer on the top surface or a transparent covering on the top surface that reacts against the expanding gas from ablative activity on the top surface. The weld is formed without physical contact between the welding device and the tab.

摘要： A scheme for electromagnetic formation of fuel cell plates is provided. In accordance with one embodiment of the present invention, a method of forming a flow field plate is provided where an electromagnetic actuator is arranged opposite a profiled surface of a die portion. The profiled surface of the die portion is configured to at least partially define a network of flow field plate flow passages. The electromagnetic actuator is configured to generate a magnetic field upon activation and a sheet of material is positioned between the electromagnetic actuator and the profiled die surface. The sheet of material is characterized by an electrical conductivity sufficient to yield a repulsive electromagnetic force between the actuator and the sheet upon activation of the actuator. The passages are formed by driving the electromagnetic actuator such that the repulsive force is of sufficient intensity to deform the sheet against the profiled die surface.
