Fakuma 2024: ALLROUNDER 570 H "Ultimate"

At Fakuma 2024, ARBURG will be presenting a concept for a high-speed medical application that can be used to produce from a grey room into a clean room. A 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 colour scheme and a conveyor belt with tunnel cover.

The exhibit will be equipped with a 64-cavity mould from Ruhla, and will process a medical PP from partner firm Borealis (Bormed HG820MO). The hot runner technology from Ewikon enables sprue-free direct lateral injection moulding. To monitor the temperatures in the mould, the injection moulding machine communicates with the hot runner controller via the GESTICA control system and OPC UA. The speed of the ejector and mould opening are synchronised. A spring assembly in the mould transfers the components from the nozzle side to the ejector side before demoulding. In a cycle time of around just six seconds, the high-performance machine produces 64 free-falling syringe plungers, each weighing 0.34 grams, for 0.5 millilitre disposable syringes. This corresponds to an output of around 38,400 pieces per hour.

The innovative product design with three-blade geometry reduces the amount of material used in this application by around 20 per cent compared to a four-blade version. A predetermined breaking point ensures that the plunger snaps when it is pulled out again, meaning that the syringe can only be used once, which contributes to patient safety.

Launched on the market in 2023, the ALLROUNDER Hidrive machines with new hybrid machine technology are particularly energy saving, economical with resources, production efficient, reliable and user friendly. Particularly impressive features include reduced purchase and operating costs, optimised energy footprint and reduced cycle times. They 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. Thanks to a wide range of options, the machines can be customised precisely to the respective requirements. "Ultimate", the highest performance variant, is specially designed for high-speed and sophisticated processes. It has an electric direct drive that allows every position to be approached extremely quickly and precisely – even over a long service life and when the machine is running at full load. The "ARBURG electro-mechanical dosage" (AED) function and hydraulic accumulator technology are included as part of the standard equipment.
