The company launched its new EcoPower Xpress 400/3300+ at Propak Africa 2019. This all-electric, high-speed injection moulding machine is designed primarily for the requirements of the packaging industry and for thin-walled applications. It replaces the TM Xpress, the high-speed hydraulic toggle lever machine model. A special feature of the EcoPower Xpress, is its high injection dynamism with up to 1 500mm/s² acceleration.
In combination with the high-precision control of its servo-electric drive, the high-speed injection aggregate of the machine reaches ultimate precision, repeatability, acceleration and speed. As if perfectly planned for the current power crisis we’re experiencing, these remarkable features and benefits come with extremely low energy consumption, which is even further reduced by the company’s patented kinetic energy recovery system (KERS). This transforms deceleration energy into electrical energy recycled within the machine.
All main movements of the EcoPower Xpress, as well as the mould height adjustment function of its clamping unit, are driven by water-cooled servo motors. For the secondary movements, such as the ejector, nozzle stroke or core pulls, a servo-hydraulic aggregate is used in the standard version. A highly dynamic servo-electric ejector is available as an add-on option. The newly developed dual five-point toggle lever system, with a self-locking function in the end position, offers an optimal solution in terms of both kinematics and energy efficiency. All linear movements, such as the moving platen and cross-head strokes are also effected via low-friction linear guides. The newly designed central grease lubrication system ensures excellent cleanness and virtually zero maintenance requirements for the entire clamping unit.
A typical feature of the EcoPower Xpress is its modular concept. The machine’s clamping and injection units are self-contained modules and can be freely combined with each other as parts of a modular system. The machine stands out by its extremely low central height and optimal access to the mould area and the injection unit. Various technical details have been adjusted to the specific requirements of thin-wall and packaging technology. For example, the distance between tie-bars and the opening stroke of the EcoPower Xpress have been significantly increased compared to the TM Xpress. This provides ideal conditions for the production of relatively flat parts in multi-cavity moulds as well as bulky hollow vessels such as buckets with in-mould labelling (IML) applications. The fixed mould platen is made of steel to ensure lowest possible platen deflection rates.
The machine’s robust design, in conjunction with its water-cooled servo motors and encapsulated direct drives, keep the machine’s noise emissions extremely low. The EcoPower Xpress thus stands for high performance with optimised use of energy, low noise emissions, and maximal cleanness, thus making a vital contribution to sustainability in plastics processing.
The EcoPower Xpress will be available through Ipex Machinery from autumn this year in 400 and 500-tonne clamping force sizes and three injection unit sizes for injection speeds of up to 600mm/s and injection pressures of up to 2 500 bar.
