At Arabplast, the plastics exhibition held in Dubai, UAE, from January 8-11, 2011, injection molding machine manufacturer Arburg will present its high-performance Allrounder Hidrive


machine. On the booth a hybrid, energy-efficient Allrounder 570 H (Hidrive) will demonstrate its performance with a high-speed, thin-walled application from the packaging sector.

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 mold. Thin-walled lids weighing 4.52 grams will be produced in a cycle time of 4.4 seconds.

The Arabplast exhibit 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.

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 reduced cycle times on the clamping side thanks to 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 mold and dosage also contribute to cycle time reductions.
