At Fakuma 2024, Arburg will demonstrate high-speed medical application with its hybrid machine technology – a hybrid Allrounder 570 H “Ultimate” will be presented to produce syringe plungers.

Arburg will demonstrate medical syringe plunger production on hybrid Allrounder 570 H “Ultimate” at Fakuma 2024.

Live demonstration to produce syringe plungers

The clean room version of a hybrid Allrounder 570 H “Ultimate” with a clamping force of 2,000 kN will be on show, with special options including a clean-air module, light grey medical color scheme and a conveyor belt with tunnel cover.

Equipped with a 64-cavity mold from Ruhla, the machine will process a medical PP from partner firm Borealis (Bormed HG820MO). The hot runner technology from Ewikon enables sprue-free direct lateral injection molding.

To monitor the temperatures in the mold, the injection molding machine communicates with the hot runner controller via the Gestica control system and OPC UA. The speed of the ejector and mold opening are synchronized. A spring assembly in the mold transfers the components from the nozzle side to the ejector side before demolding.

In a cycle time of about six seconds, the Allrounder machine produces 64 free-falling syringe plungers, each weighing 0.34g, for 0.5ml disposable syringes.

Allrounder Hidrive machines

The Allrounder Hidrive machines come in sizes 470, 520 and 570 with clamping forces of 1,000, 1,500 and 2,000 kN and in “Comfort”, “Premium” and “Ultimate” performance variants.

Gestica control system can be applied to increase part quality. Take the syringe plunger demonstration as example, the “aXw control PressurePilot” compensates for errors in the filling process and keeps the mould filling stable, achieving injection precision on a par with electric injection unit.

Arburg also offers functions such as “Stability Monitoring” for reduced scrap and “Precision Dosing” for precise screw control.
