Arburg will be present at Fakuma 2023 during October 17 to October 31 in Friedrichshafen, Germany, with nine exhibits on Stand 3101 in Hall A3, plus 10 additional machines on partner stands. One highlight is the premiere of the Allrounder 520 H. The new machine in the hybrid Hidrive series with innovative machine technology is engineered for saving energy and conserving resources, as well as being production-efficient, user-friendly and reliable.

The machine technology of the Hidrive series has been significantly enhanced, with the new hybrid machines featuring an optimized energy footprint and reduced cycle times. Following the launch of the 470 H milestone machine earlier this year to mark "100 years of the Hehl family company," the next step has now been taken with the size 520 and 570 machines.

New size 520 with 1,500 kN clamping force

The size 520 with a clamping force of 1,500 kN will be on show for the first time at Fakuma 2023. The exhibit, an Allrounder 520 H Premium, will use a 1+1+1-cavity mold to produce three different molded parts from ABS in a cycle time of around 50 seconds: a machine base, a feed hopper and a controller. These three components are subsequently separated from each other in a cutting station and round off a set of 15 parts for a model Allrounder on a scale of 1:18.

In this application, the Moldlife Sense computer system enables sensor-controlled mold monitoring over the complete life cycle. The recorded data is passed via an OPC-UA interface directly to the Gestica control system, which displays corresponding malfunctions as well as performance-dependent maintenance intervals, thereby enabling predictive maintenance.

The new Multilift Select 8 linear robotic system with an 8 kg load removes the molded parts and places them in a box. A box changer ensures an autonomy of about two hours.

Cost- and resource-saving alternative

The Hidrive series combines an electric energy-efficient and precise clamping unit with a powerful and dynamic hydraulic injection unit. Compared to all-electric and hydraulic machines, it is characterized by significantly reduced acquisition and operating costs as well as a better energy and carbon footprint.

A novelty in the new hybrid Allrounder Premium machines is flow splitting as standard, with cutting-edge Varan valve technology used to split the main pump's available flow volume when required. This enables simultaneous movements of hydraulic auxiliary axes with programmable control such as the ejector and core pull — without technology stages or multi-pump technology.

Compared to corresponding hydraulic machines, the energy footprint of the new Allrounder H is up to 50% better. In addition, the carbon footprint can be significantly reduced. Thanks to a new oil management concept, the new Allrounder machines require up to 35% less oil. The required cooling water capacity can be reduced by up to 70%. The dry cycle time is also reduced by around 40%.

Three performance variants

Thanks to its many options, the Allrounder 520 H can be adapted precisely to individual customer requirements. Like the size 470 H machine, it is available in three performance variants: "Comfort", "Premium" and "Ultimate." The first two variants feature the Arburg servo hydraulic system (ASH) as standard, with the speed-controlled, water-cooled servo motor adapting continuously to the actual power requirement, thus enabling particularly energy-efficient and low-emission operation. At the same time, however, the machine's cooling requirements and noise level are also significantly reduced.
