摘要： An injection apparatus including a plasticizing unit (2) that plasticizes a raw material resin and an injection unit (3) that injects a plasticized molten resin. The plasticizing unit includes a heating cylinder (20) having a foaming gas injection valve and a screw (21) provided inside the heating cylinder. The rotation and advance and retreat movements of the screw are controlled such that a raw material resin is plasticized by the screw and a foaming gas injected from a foaming gas injection valve is dissolved in the plasticized molten resin. After the screw retreats to a prescribed position according as the molten resin accumulates in the front end side of the heating cylinder by the screw that is rotating, the screw advances with rotating to cause the molten resin which has been accumulated in the front end side of the heating cylinder to be transferred to the injection unit.

摘要： Apparatus for moulding articles of synthetic plastics. Plasticized plastics material is fed by a screw within a cylinder, along the cylinder to a nozzle from whence the material is injected into the mould cavity. The feeding of the material into the mould cavity is however effected by rotation of the screw almost in its forwardmost position instead of by longitudinal movement of the screw from its rearwardmost to its forwardmost position. The longitudinal position of the screw is adjusted during filling of the mould cavity by biasing apparatus acting axially on the screw and controlled by means sensing the position of the screw.The temperature distribution throughout the cylinder, the nozzle, the screw and the screw tip is controlled by separate cooling circuits for the various zones, the various cooling circuits coming into operation at various times during a moulding cycle, as determined by timing apparatus.

摘要： Products having a relatively large thickness such as optical lenses for various industrial applications are molded by an injection molding machine by advancing the screw by operating an injection cylinder for filling metered quantity of a molten resin into a metal mold. The screw is rotated while it is being advanced. A plurality of position setters are provided along the stroke of the screw and their outputs are respectively compared with the output of a screw position detector by using comparators. The outputs of the comparators are used to effect a program control of screw rotation in multistages. According to a modified embodiment, during the filling step effected by screw rotation, the injection speed is varied stepwisely. The injection speed is reduced to zero for a short interval and then increased again. The number of revolutions of the screw, however, is maintained at a constant value until the injection speed is increased again.

摘要： 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.
