New performance for the packaging industry

New performance for the packaging industry
In the packaging industry, fast, high-quality volume production using reliable and efficient technology is essential. With the new "Packaging" version of the electric and hybrid Allrounder Alldrive and Hidrive machines, Arburg meets these demands. The two high-performance machine series offer high productivity and reduced energy consumption. These Allrounders bear a "P" for "Packaging" following the machine designation.

The "Packaging" versions of the Allrounder Alldrive (A) and Hidrive (H) have been consistently enhanced as complete, high-performance solutions. The machines have been optimised in almost all areas for this purpose.

One excellent example of this is adaptation of the combination of "distance between tie bars - clamping force - opening stroke" to the performance characteristics to suit the requirements of the packaging industry. The "Packaging" versions are consequently available in the following sizes: the Allrounders 570 A and H feature a clamping force of 1,800 kN, Allrounders 630 A and H 2,300 kN, Allrounders 720 A and H 2,900 kN, Allrounders 820 A and H 3,700 kN and Allrounders 920 A and H 4,600 kN.

The torsionally rigid, longitudinal steel machine base supports accommodate heavy mould weights and compensate for high load changes during mass movements. The FEM-optimised mounting platens combine the necessary rigidity with low weight. Together with servo-electric toggle-type clamping units, this facilitates extremely fast opening and closing movements, leading to shorter overall cycle times. At the same time, energy recovery during braking ensures that the energy applied is used even more efficiently. Energy savings totalling up to 30% can be achieved in comparison with hydraulic clamping systems.

In the case of the "Packaging" version, the next higher injection unit size is also available for each particular machine size. This means that up to four injection units are available for each machine type, ensuring that the high plasticising performance required in the packaging sector can be achieved. Servo-electric dosage drives ensure fast operation across cycles, short dosage times and maximum productivity. The use of barrier screws ensures homogeneous melt preparation and a high material throughput. Injection involves either servo-electric or hydraulic accumulator technology via position-regulated screws. With an appropriately dynamic filling process, active acceleration and deceleration is achieved. Together with higher injection speeds of up to 500 mm/s, this enables the short injection times which are required in the packaging sector. If production sequences need further optimisation, injection can be started simultaneously with the "mould closing" movement as standard. Once again, the aim here is to reduce the cycle times in order to achieve high productivity in manufacturing.
