Machinery innovations save energy for moulders
Hardware, software, and renewable energy developments power advances in energy management options for injection moulders. Mikell Knights finds out more
Injection moulding machinery OEMs continue to develop energy-saving technologies that curb energy consumption while delivering high perfor- mance, from hardware developments like new machinery models and lines that debut new or updated motor and gear designs, to software advances that make it easier to identify, monitor and manage energy consumption at a machine, from a production cell or plant wide. Moulders are also embracing renewable energy technologies at their facilities for savings. Wittmann Battenfeld’s newest machine option,
the SmartPlus line of high-performance, cost-effec- tive servo-hydraulic machines, is based on the SmartPower series but with selected technology options and a limit on equipment choices and suited to more standard, less complex moulding applications. The model line has been available since the

fourth quarter of 2021 to an extended circle of customers, with the first series of clamping forces ranging from 60 to 180 tonnes. Features include an intelligent, energy-saving highly dynamic servo drive system and a booster unit specially devel- oped in-house that increases the machine’s response speed and enables higher clock frequen- cy. The booster/amplifier unit is part of Wittmann Battenfeld’s upgraded Drive-on-Demand 2.0 drive technology, which combines a fast-responding, speed-controlled and air-cooled servo motor with a high-quality fixed displacement pump. The drive unit is only activated for movements and pressure generation but remains off during cooling times or cycle breaks and consumes no energy. The drive technology also lowers the thermal
load, preserving oil quality and reducing overall cooling expenses, as oil cooling can normally be dispensed with. The amplifier is now available on
