Hybrid high performance at its finest

Arburg exhibited very successfully during the Arabplast 2011. With a high-speed, thin-walled application, the high-performance Allrounder Hidrive machine was a crowd-puller and gathered excellent feedback from the visitors.
Appropriately for the packaging sector, which dominates the Arabian market, thin-walled lids were produced on a high-performance Allrounder 570 H with a 4+4 cavity mould, in a cycle time of 4.4 seconds. With a clamping force of 2,000 kN and a size 800 injection unit, this machine belongs to the medium-sized range of the successful Hidrive series, the Hybrid machines of which are characterised by high productivity, short cycle times and energy efficiency. These machines are now available in the range up to 5,000 kN.
Such high-tech machines from Arburg fully meet the high demands of the booming Arabian market. Since the beginning of 2009, Arburg has served this market with its own sales and service office in the United Arab Emirates. For 2011, specific projects are already in progress.

High-performance machine concept
The hybrid Allrounder 570 H with a clamping force of 2,000 kN and size 800 injection unit is equipped with a 4+4-cavity mould. Thin-walled lids weighing 4.52 grams will be produced in a cycle time of 4.4 seconds. This is the third largest machine from the Hidrive series, which comprises six machine sizes and covers a clamping force range of 600 to 5,000 kN. The high achievable production capacity of the Allrounder H is the result of meticulously combining tried and tested servo-electric and hydraulic components from the modular Allrounder system. The servo-electric clamping units and are complemented by hydraulic injection units with electro-mechanical dosage drive and position-regulated screw. This is further enhanced by performance-adapted hydraulic accumulator technology.
The Allrounder H machine concept has been specially designed for a high production capacity: Thanks to the hydraulic accumulator technology and the generously-sized injection units, Allrounder H machines also boast a correspondingly high injection performance in relation to the clamping force. Also, in Allrounder H machines, the independent movement axes ensure a considerable reduction in cycle times. The high-precision, cost-effective toggle-type clamping unit can also be used to tap potential for significantly reduced cycle times on the clamping side thanks to extremely short dry cycle times, high acceleration and final speeds as well as simultaneous movements of the clamping unit and ejector. With regard to the injection unit, the combination of position-regulated screw, hydraulic accumulator technology and servo-electric drives for the mould and dosage also contribute to cycle time reductions.

Energy efficiency
The high efficiency of the toggle-type clamping unit and servo-electric dosage drive  guarantees energy-efficient operation of the Allrounder H machines. In addition, the energy recovery of the servo motors during braking also has a beneficial effect on the machines' energy consumption. As well as the servo-electric drives and braking energy recovery, Allrounder H machines also use performance-adapted hydraulic accumulator technology with the minimum amount of installed pump capacity and motors of efficiency class EFF1. As a result and depending on the application, the energy-saving potential of the Hidrive machines can be as much as 40 percent. All Allrounder H machines bear the Arburg "e2" energy efficiency label as an indication of their energy-optimised operation.
High output and availability as well as energy-optimised operation guarantee high cost effectiveness. Consequently, Hidrive machines are also suitanike
