Arburg to present its Allrounder 520 H at Fakuma 2023
A novelty in the new hybrid Allround-
er "Premium" machines is flow split-
ting as standard, valve technology is
used to split the main pump's available
flow volume when required.
Arburg claims that this enables si-
multaneous movements of hydraulic
auxiliary axes with programmable
control such as the ejector and core
pull – without technology stages or
multi-pump technology. Arburg says
that this saves energy, costs and space
on the machine and increases produc-
tion efficiency.
