Fakuma 2009: Arburg Shows New Allrounder Producing Syringes

The Allrounder 520 H with a clamping force of 1,500 kN and an injection unit 800 produces syringe barrels from PP at Fakuma.

Complying with the energy-efficiency trend, which is once again the prevailing theme at this year’s Fakuma trade show, Arburg is showing its two Allrounder machines in Hall A3: the electric Alldrive and the hybrid Hidrive. At the injection moulding event, the German machine manufacturer demonstrates the use of its new Hidrive series in the demanding med-tech field with the production of syringe barrels. The Allrounder 520 H has a clamping force of 1,500 kN and a size 800 injection unit. Equipped with a 32-cavity mould with a full hot runner system from Schöttli, the machine produces syringe barrels from Polypropylene (PP) in a cycle time of six seconds.

“The hybrid machines combine the servo-electric clamping unit of the Allrounder A and the hydraulic injection unit of the Allrounder S with hydraulic accumulator technology and servo-electric dosage,” says Nicolai Gayer, Arburg Public Relations. “That way we are able to provide maximum production performance at shorter cycle times and reduced energy consumption.” These attributes make the machines suitable for the production of components for the high-end sector such as medical technology, which requires not only precision and hygiene but also high-speed machines.

The reduced cycle time can be achieved through rapid, dynamic mould movements of the servo-electric toggle-type clamping unit, simultaneous movements of independent movement axes, high injection moulding dynamics and the large injection flow. ”We offer a holistic concept but our machines are not off the rack,” stresses Gayer. “Every machine is manufactured to customer specification, according to the application.”
