Abstract: Injection-molding machine arrangement comprising at least one injection molding machine with at least one, especially internal, machine control system—especially with a stored program control and/or with associated actuators and/or sensors—for computer-assisted process monitoring and control of the injection molding machine, wherein the injection-molding machine arrangement provides at least one mains supply transmission unit for data transmission via at least one mains electricity supply—preferably in a bi-directional and/or real-time-capable manner.

Abstract: Injection unit for an injection moulding machine, with a housing (1) carrying a plasticising cylinder (2) and with a transverse support (8) arranged movably in the housing (1), which support is connected to a plasticising screw (9) mounted in a rotatable and longitudinally displaceable manner in the plasticising cylinder (2), wherein piston rods (6) projecting on both sides in the longitudinal direction of the injection unit are connected to the transverse member (8), the free ends of which (6a, 6b) each enter into a cylinder chamber (7a, 7b) in the manner of plungers.

Abstract: An injection moulding machine having a machine frame (1), a stationary and a movable mould mounting plate (2,8) for fixing mould portions (4,9) and an injection unit (5) which opens into the mould through the stationary mould mounting plate (2), wherein the force applied by the closing mechanism is transmitted through the machine frame instead of through bar members and the injection unit (5) is in rigid connection with the stationary mould mounting plate (2).
