New Allrounder 470 H: Arburg presents a very special anniversary gift

The 100-year anniversary of the Hehl family company has set the stage for Arburg's latest piece of machine technology, the hybrid Allrounder 470 H. This anniversary machine delivers a high performance across the board: it saves energy, conserves resources, is production-efficient, user-friendly and reliable.

The combination of electric clamping unit and hydraulic injection unit significantly reduces acquisition and operating costs as well as the carbon footprint of the new Allrounder 470 H from Arburg. With Comfort, Premium and Ultimate performance variants, various injection units and a wide range of options, the machines can not only be precisely adapted to specific customer requirements — they also mark the start of a new generation of machines from the German manufacturer.

The anniversary machine is particularly interesting to customers who are looking for an energy-saving alternative to hydraulic machines, for example, but who also want to benefit from their proven benefits. When designing the new Allrounder 470 H, the engineers significantly enhanced the company's technology to optimise the energy footprint and reduce cycle times. Contributing factors include the new oil management concept for which a patent is now pending, flow rate splitting for simultaneous movements of hydraulic secondary axes and the extended use of the Arburg servo hydraulic system.

Compared to a similar hydraulic machine, the energy footprint of the Allrounder 470 H is up to 50 percent better, the company claims, and depending on the application, up to 12,000 kilogram of CO2 could be saved each year. The new oil management concept also helps to conserve resources: For one thing, around 35 percent less oil is needed, and for another, waste machine heat is used to pre-heat the oil. In addition, the required cooling water capacity is also between 50 and 70 percent lower. A reduction in the dry cycle time of up to 33 percent results in significantly greater production efficiency.

Additional design simplifications have been implemented to ensure that the machine is extremely user-friendly. A real-time Ethernet bus replaces the individual ribbon cables of the control modules, which increases the service and service life of the machines. The distribution of the hardware on and in the machine base has been completely restructured. The control manifold and hydraulic accumulator technology have been moved inside so that there is more space for peripheral equipment at the rear side of the 470 H Allrounder machines. The electrical, hydraulic and water media circuits have been separated, which simplifies assembly, service and conversion. Hydraulic and water circuits are located in the machine base. The pneumatic and central lubrication systems are on the operating side, which also means more flexibility with options on the rear side. This optimised distribution saves time during service and in daily use. Finally, arranging options and interfaces uniformly on the rear side of the machine also provides more clarity and order around the Allrounder H.
