Saving grace: the benefit of energy management


Injection moulding is an energy-intensive process, but many methods – including electrification, software systems and temperature control – help to save energy use


Driven partly by sustainability and a lot by high electricity prices, modern manufacturing is on a quest to cut its energy use – and has many clever ways to do it. Energy monitoring has helped German injection


moulder Filthaus to control costs on a production cell. The company is using an iMAGOxt energy management system from Wittmann on its 26 injection moulding machines. “Without it, we would never have seen a high no-load consumption of a work cell,” said Stefan Filthaus, managing partner of the company. “Now we can address this issue, eliminate hidden electricity consumption and save several thousand Euros per year.” iMAGOxt is a cloud-based energy management


software that helps injection moulders analyse energy consumption. To visualise it in real time, it collects data at certain consumption points,

analyses trends and presents results in the form of clear graphs. Filthaus has two major business segments:


packaging and technical parts. For both, a high proportion of total unit costs – around 20% – is incurred by energy consumption. “To remain competitive, we must compensate the rising energy prices by reducing our energy consumption,” he said. As well as software, iMAGOxt includes current-


measurement sensors, which transfer their readings to the software via a cloud. These are installed on individual machines, whether from Wittmann or other suppliers. Individual consumption figures can be visualised in either kWh or tonnes of CO2 emissions. These values are typically lower on sunny days, as Filthaus has a photovoltaic system. iMAGOxt also helps the company analyse power peaks. “We can see the consumption flow and
