A static mixer for an injection molding machine comprises a plate having an inlet face, an axially opposed outlet face, and a longitudinal axis extending therebetween. A plurality of bores extend through the plate from the inlet face to the outlet face. Each bore extends along a bore axis that is inclined relative to the longitudinal axis. The inlet face comprises an inlet face peripheral portion and an inlet face central portion. The outlet face comprises an outlet face peripheral portion, and an outlet face central portion. A core extends longitudinally between the inlet face central portion and the outlet face central portion.

An extruder has a barrel extending from a feed inlet end to an extruder outlet end. The barrel has an inner surface, an outer surface, and a wall thickness between the inner and outer surfaces. The extruder also has at least one heating member positioned provided on the barrel; a screw drive motor drivingly connected to a rotatably mounted screw positioned within the barrel, whereby the screw is rotatable at various revolutions per minute (RPM); and a controller is operably connected to the screw drive motor to adjust the RPM of the screw based upon a temperature of material passing through and/or being extruded from the barrel. Methods for operating an extruder filling a mold are also provided.

Disclosed herein is a method for manufacturing a rotor, the method including an injection process of injecting a bonded magnet material into a cavity of a molding die generating a magnetic field in the cavity so that the bonded magnet material is poured into each of the magnet slots in the rotor core set in the cavity through one of openings of each magnet slot, wherein the molding die used in the injection process has gates which respectively open at positions corresponding to regions, each of which ensures a view from the one of openings to the other opening of the magnet slot along an axial center of the rotor core.

In a method for operating an injection moulding machine in the absence of a backflow barrier, plastic melt is injected by a plasticising device into a cavity in a screw antechamber of a plasticising screw adapted to rotate about a longitudinal axis and to move translationally by a drive unit during an injection phase and a holding- pressure phase. A rotational drive of the drive unit is controlled such that a speed of the plasticising screw causes overlay of a backflow of the plastic melt from the screw antechamber back into screw threads of the plasticising screw by an opposing delivery flow as a result of a rotation of the plasticising screw due to a translational injection movement of the plasticising screw. A differential flow is established from the backflow and the opposing delivery flow and influenced at least during the injection phase by influencing the speed of the plasticising screw.

A device for imparting vibrational energy to polymeric pellets in a feed path of an extruder is disclosed. The device includes a feed path vibrator having an elongate imparting portion for being disposed within the feed path of the extruder, and a transfer portion extending from the imparting portion. The transfer portion is configured for coupling to a source of vibration energy, and the elongate imparting portion includes at least one twisted portion along its length.
