A Magnetic Gear Modulator (MGM) of a Concentric Magnetic Gear (CMG) is manufactured by injection molding a modulator cage over angularly spaced apart MGM pole pieces made of a magnetically conducting material. The pole pieces are initially connected by a support ring, or held by a fixture. The modulator cage is preferably a thermally conductive strengthening fiber filled plastic, a carbon fiber plastic, a carbon fiber filled plastic material, a glass material, or a high performance composite plastic molding material. After molding, the outer and/or inner portions of the molding material, and support ring if present, are machined away preferably exposing both inner and outer faces of the pole pieces embedded in the modulator cage. An MGM made using injection molding over a connected support ring and pole pieces reduces cost, and a carbon fiber plastic modulator cage increases strength.

An injection molding apparatus and method of fabricating a molded part are provided. The apparatus may include a barrel, a nozzle enclosing an end of the barrel and defining an opening in fluid communication with an inside of the barrel, and an extrusion screw positioned at least partially inside the barrel and rotatable relative to the barrel. The extrusion screw may include a screw tip. Relative axial movement between the barrel and the extrusion screw may open or close the opening of the nozzle to permit or prevent, respectively, material flow through the opening of the nozzle. The method may include clamping a mold, opening a nozzle, rotating the extrusion screw to pump a molten material into the mold until the mold is filled, closing the nozzle, and unclamping the mold to release a molded part.

Within examples, elastomeric apparatuses for use in manufacture of a composite component, and methods for altering a surface rigidity of an elastomeric apparatus for use in manufacture of a composite component are described. In one example, an elastomeric apparatus comprises an elastomer housing, and a plurality of magnets within the elastomer housing at predetermined positions to provide surface rigidity to the elastomer housing based on one or more alignments of certain magnets of the plurality of magnets due to magnetic forces. An increase in temperature causes a loss in one or more of the magnetic forces of one or more of the plurality of magnets resulting in a reduction of stiffness of the elastomer housing at corresponding predetermined positions.

The manufacturing method of a motor core includes attaching an ID code to a stack of blanked members in which a magnet insertion hole to fill with a resin material is formed, the ID code containing information in accordance with a type of the stack, reading the information from the ID code which is attached to the stack, and setting a mold condition based on the information read from the ID code. The mold condition includes at least one type of condition including: the resin material to be injected to the magnet insertion hole, an injection amount of the resin material, and a discharge position of the resin material. A mold device is controlled to inject the resin material to the magnet insertion hole in accordance with the mold condition.

An embodiment of a method for operating a direct write device includes operating a first pump to deliver a first fluid feedstock to a first inlet of a multiaxial needle and operating a second pump to deliver a second feedstock to a second inlet of the multiaxial needle. At least the first and second feedstocks are simultaneously drawn or injected through respective first and second axial passages in the multiaxial needle. At least the first and second feedstocks are combining to a common outlet of the multiaxial needle, forming a single multicomponent deposition material having multiple discrete phases without applying external heat to the first or second feedstocks within the needle. The multicomponent deposition material is deposited from the common outlet onto a substrate.

An additive manufacturing system for extraction of impurities in additive manufacturing material, the system including an additive manufacturing machine for manufacturing a part using additive manufacturing material. The system may additionally include a conductive plate adjacent to the additive manufacturing material. The system can further include an energy source for distributing an electric charge through the conductive plate adjacent to the additive manufacturing material. Distributing the electric charge through the conductive plate can attract impurities from the additive manufacturing material to the conductive plate
