EcoPower Xpress 400 – 500 t

EcoPower Xpress machines are high-performance machinery for extremely short cycle times with clamping forces ranging from 400 to 500 t. The innovative EcoPower Xpress series stands for high dynamic, speed and accuracy. Due to their high performance and short cycle times the machines are especially suitable for the packaging and thin-wall industries.

The high-speed machine

toggle lever bolts

The EcoPower Xpress is an extremly fast toggle-injection molding machine whose main movements are driven by water-cooled servo motors. The model heigth 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 screw infeed movement for injection and retraction of the screw during plasticizing is driven by twin herringbone gear racks with symmetrical force transmission.

The clamping unit of the EcoPower Xpress is a 3-platen/4-tiebar 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.
