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."
