Arburg demonstrates high-speed combined with high-precision at the Plastec West

High-speed IML application based on the Allrounder 570 A / All cyclic subprocesses automated

(PresseBox) (Lossburg, ) The enormous potential of the fully-electric Allrounder A will be presented by Arburg at the Plastec West, which will be held from 29 to 31 January 2008 in Los Angeles/Anaheim, on the basis of an illustrative example. In hall B, stand 3927, a fully-electric Allrounder 570 A with a clamping force of 2.000 kN (220 US tons) will be presented with a high-speed IML application from the packaging sector.

Precise, repeatable, clean operation and incredibly fast and energy-efficient too: These are the performance features of the fully-electric Allrounder A. The drive concept of these machines is as suitable for the production of technical medical parts as for applications in the food, packaging and automotive industries.

Allrounder 570 A exhibit
At the Plastec West, Arburg will demonstrate the capability of the Allrounder A with an IML application: Labelled tubs will be produced in a two-cavity mould in a cycle time of only 2.8 seconds. This complex project integrates all the necessary automation elements around an Allrounder 570 A with a clamping force of 2,000 kN (220 US tons), which is currently the largest electric injection moulding machine in the Arburg machine range. The entire IML automation process was adapted and optimised by Wittmann. It provides the labels for the tubs, separates, transfers and places them in the mould, removes them and, finally, stacks the finished items on a conveyor belt according to cavity.

The production sequence
First of all, two labels are picked up by the handling device, placed on the ejector side of the mould by a precision-adjustable transfer hand and precisely positioned. The tubs are simultaneously removed from the nozzle side. This process has a complete cycle time of 2.8 seconds. Time is saved during production through the simultaneous movements of the electric axes, the rapid peripheral routines, the short inmould lamination cycle and the simultaneous part removal and label insertion.

With this system, Arburg will demonstrate that IML applications can produce fast, reliably and in high quality, as well as in high volumes. The resulting cost efficiency ensures that the customer achieves the return on investment in a very short time, which is so important in this sector.
