In manufacturing a magnet embedded core, creation of flash, and problems associated with flash are prevented. A device for manufacturing the magnet embedded core comprises a base (32) comprising an upper surface at which a resin pot chamber (64) for storing molten resin opens, a separator plate (36) detachably placed on the upper surface of the base (32) to support a rotor core (2) thereon and having a gate (50) and a cull opening (52) communicating the magnet insertion hole (4) of the rotor core (2) with the resin pot chamber (64), and a plunger (62) movably provided in the resin pot chamber (64) to press the molten resin in the resin pot chamber (64) into the magnet insertion hole (4) via the gate (50) and the cull opening (52), wherein an annular recess (66) is formed on the upper surface of the base (32) so as to extend outward of the resin pot chamber (64) and communicate with the resin pot chamber (64).

A method for making structural foam parts having continuous aligned fibers includes placing an assemblage of fiber-bundle-based preforms in an injection mold, creating a melt flow of resin and, optionally, short, loose fiber, and adding foaming agent to the melt flow. When the foaming agent/melt flow mixture is introduced into the injection mold, the foaming agent foams. The assemblage is structured and positioned so that fibers therefrom adopt a desired alignment and position in the final part. Structural foam fills the remainder of the volume of the part.

Systems and approaches for controlling an injection molding machine having a mold forming a mold cavity and being controlled according to an injection cycle include obtaining a pattern for the injection cycle, operating the injection molding machine to inject a molten material into the mold cavity, and measuring a cavity pressure value of the mold cavity during the mold cycle. Upon measuring a nominal cavity pressure value, a pattern recognition portion of the injection cycle that is at least partially dependent on the obtained pattern commences where a driving force being exerted on the molten material is adjusted such that the measured cavity pressure matches the obtained pattern for the injection cycle.
