Osterwalder delivers its first 1000kN multi-plate servo electric press
August 21, 2024
Osterwalder AG, Lyss, Switzerland, reports that it delivered its first 1000kN servo-electric multi-plate press, the OPP 1000 in July 2024. The press is said to use a unique combination of the servo electric main-drives, hydraulic plate-drives for the powder transfer phase and CNC controlled mechanical stops.
“Around 2015 it became clear to us that the future of powder pressing is electric. These presses have only advantages: more precision, reduced energy consumption, reduced noise, reduced maintenance costs, etc. With the latest developments in electro-mobility and micro-mobility, it also became clear that after the successful launch of the OPP 2000 (Osterwalder’s 2000 kN press) in 2018 and the OPP 5000 (Osterwalder’s 5000 kN press) in 2022, the next one will be smaller again,” commented Rolf Graf, owner and CEO.
“This press is not only the latest of the new multi-plate product-line, it is also the most mature press Osterwalder has made,” stated David Benczur, Global Head of Sales Iron Powder. “The structure is based on the successful design of the previous hydraulic presses of the same size, the Control System is derived of larger OPP presses, and it operates with the latest version of our well- known HMI. But it also includes some new tricks, for example a kinetic energy battery that reduces the peak-currents.
Osterwalder launched the world’s first CNC controlled powder press in 1989. The OPP 1000 is the latest member of the multi-plate series.
“Our discussions with our customers conclude usually on short returns on investment (ROI), typically within 1-3 years, sometimes even comparing to already amortised used presses. High stroke-rates play a role of course, but precision, reliability and also short set-up and learn-in times for the work force are equally important to maximise good parts produced continuously week after week.”
