The EcoPower Xpress is an extremly fast toggle injection molding machine whose main axes are driven by water-cooled servo motors. The model height adjustment system of the clamping unit is also driven by an electric motor. A hydraulic system with servo drive is used for the secondary movements.
The machine is equipped with a highly dynamic injection unit. The injection stroke as well as the screw retraction before/after plasticizing are realized with twin herringbone gear racks with symmetrical force transmission.
The clamping unit of the EcoPower Xpress is a 3-platen/4-tie-bar system with a 5-point toggle lever, self-locking in the end position, with a drive system consisting of a servo motor and rack-and-pinion gears. The highly rigid moving platen travels on a moving carriage on the machine frame, supported by linear guides and rotating roller bearings, without contact to the tie-bars.
