Embodiments disclosed herein relate to a composition useful for forming a stator or a portion thereof. The composition may include: a curable elastomer; a fiber or fibrous compound; a fiber dispersion compound; and optionally carbon black.

A resin injection apparatus includes: a mold die and a receiving die configured to hold a core body in an axial direction of the core body, the core body having a resin formation region serving as a region where resin is to be formed by injection of molten resin; a plurality of plungers; and a pot group attached to the mold die, the pot group including a plurality of pots proximately located next to each other in a direction. Each of the plurality of pots has a through hole in which a corresponding plunger of the plungers is insertable. The plurality of pots have a first coefficient of thermal expansion that is lower than a second coefficient of thermal expansion of the mold die.

A thermoplastic engine cover for an internal combustion engine has a plurality of mounting holes for mounting the thermoplastic engine cover to an internal combustion engine. At least two datum locator formed on or arranged on the thermoplastic engine cover. At least one through opening configured to receive a rotatable shaft of the internal combustion engine. The at least one through opening has an internal diameter sized to provide an annular clearance gap between the seal carrier and an adjacent circumferential wall of the at least one through opening, to allow final positioning of the seal in the annular clearance gap to a final position in which the seal and seal carrier are positioned in a dimensionally correct position relative to the at least two datum locators. The seal carrier is then welded to the thermoplastic engine cover.

To provide a polyarylene sulfide (PAS) resin composition and a PAS resin molded article that are excellent in mechanical strengths such as impact resistance while maintaining excellent heat resistance of the PAS resin, and methods for producing the PAS resin composition and the PAS resin molded article. Specifically, provided are a method for producing a long fiber-reinforced PAS resin molded article, the method including obtaining a long fiber-reinforced PAS resin composition containing a PAS resin and a fiber reinforcing material having a fiber length of more than 5 mm, subsequently subjecting the resin composition and a PAS resin to dry blending, and subsequently subjecting the dry-blended substance to melting and subsequently to melt-molding; the long fiber-reinforced PAS resin composition; and a method for producing the long fiber-reinforced PAS resin composition.

Provided is a manufacturing device and a manufacturing method for a rotor core that can prevent damage from being caused to an end of a magnet due to movement of the magnet when injecting a resin material. Included are a first mold including a fitting recess that fits and holds a laminated iron core in which a magnet is inserted into a magnet insertion hole, a second mold that is engaged with the first mold and clamps and seals the laminated iron core together with the first mold, a resin injection unit that is provided to the second mold, and injects a resin material into the magnet insertion hole, and a magnet positioning and holding mechanism that positions and holds the magnet in a state of being fit into the fitting recess of the first mold.

A stator for use in a positive displacement motor or a progressing cavity pump. The stator comprises an elastomer mix preferably including rubber and a fiber reinforcement. The fiber reinforcement includes a plurality of fibers. The elastomer mix is formed into a stator via an injection molding process. The injection molding process includes a shear flow step in which shear flow is induced in the elastomer mix while the elastomer mix is in an uncured state. The shear flow modifies the orientation of the fibers into an advantageous modified fiber orientation. Shear flow is induced preferably via differential rotation of injection mold assembly elements during the injection molding process. Methods of manufacturing the stator are also disclosed.

A motor of the present invention includes a stator having windings. The stator includes: a cylindrical outer member; a mold resin portion that molds the windings with a resin; and a stress non-transmitting portion provided between the mold resin portion and the outer member so as not to transmit stress to the outer member due to shrinking of the mold resin portion or reduce the amount of transmitted stress.

An apparatus for forming pre-shaped insulating sheets comprises first bending station and a second bending station. The first bending station is used for bending a flat sheet of insulating material into a Z-shaped sheet (5). The second bending station is used for bending the Z-shaped sheet into an S-shape. The first and second bending stations comprise pairs of first (13a, 13b) 13b and second bending operators for creating bending movements.

This invention provides: a method for manufacturing a supercharger compressor housing, in which a supercharger compressor housing is manufactured through at least a local heating step for locally heating an area to be heated, which is part of an abradable seal, and a mounting/fixing step for mounting and fixing the abradable seal to a mounting/fixing surface of a compressor housing main body, the locally heated area to be heated being inserted while being deformed into groove parts provided to the mounting/fixing surface in the mounting/fixing step; and a compressor housing created using this manufacturing method.

Various methods and assemblies are provided for producing composite components having formed in features. For example, a method may comprise depositing a composite material on a base tool; bringing a feature forming tool into contact with the composite material; and processing the composite material with the feature forming tool in contact with the composite material. The processed composite material forms a green state composite component. The feature forming tool comprises a sheet having one or more elements for interacting with one or more elements of the base tool to form one or more features of the composite component. In some embodiments, the method also may comprise sealing a bag around the feature forming tool and the composite material after bringing the tool into contact with the composite material and removing the bag and the feature forming tool from the green state composite component after processing.
