Energy-saving Sumitomo hydraulic machines

Energy-saving Sumitomo hydraulic machines
Energy efficient injection moulding is actively driven by the energy-saving drive activeDrive of the Systec hydraulic series from Sumitomo (SHI) Demag Plastics Machinery GmbH. A reduction in energy usage of up to 60 % is possible according to application.

As ever, hydraulically driven injection moulding machines represent a large market. Sumitomo (SHI) Demag offers its multifunction machine Systec at a clamping force from 350 to 1,200 kN with a fully hydraulic clamping unit, and from 1,600 to 20,000 kN with a toggle clamping unit. Numerous production-efficient building blocks are available for the Systec, which support the processor in the realisation of the best possible production efficiency. The energy-saving drive activeDrive guarantees a dynamic performance adjustment to the respective requirements and in doing so ensures the optimum degree of efficiency and minimum loss, especially in the partial load area and when idling. The combination of a high-dynamic, frequency-controlled servomotor and a constant pump enables energy-savings of 30-60 per cent compared with a standard hydraulic drive.

When investing, many companies decide on sustainable solutions, which offer the greatest degree of efficiency even under future production conditions. The increasing pressure of costs for power, water and other operating materials can be met through investment in new technologies. Therefore, Sumitomo (SHI) Demag already delivers every second machine with the hybrid concept activeDrive. "We are in the meantime seeing a huge increase in activeDrive drives, even in the small hydraulic machines, and this although here the return on investment (ROI) for our customers takes somewhat longer than for machines with greater tonnages", states Marketing Manager Bernd Tröger, and continues: "Sustainability is shifting increasingly into focus during investment. Here we are providing exactly the right answers with our "Blue Technolution" system solutions."

activeDrive and activeMotionControl increase performance and lower energy usage

As a manufacturer of technical plastic injection-moulded parts for vehicle construction, Borscheid + Wenig GmbH in Diedorf by Augsburg has been operating several Systec machines for many years. A further Systec 50-310 with the technology building blocks activeDrive and active MotionControl will be delivered shortly and support the company in the framework of its environmental management. The managing partners Norbert and Sven Borscheid and Carlo Wenig are extremely satisfied with both the performance of the hybrid machines with activeDrive and activeMotionControl as well as with the energy-saving. "The Systec machine offers a good price/performance ratio and, with the energy-efficiency building block activeDrive we additionally save energy and can considerably reduce the cycle time further thanks to activeMotionControl", say the partners.
