During the last decades the Danieli Group has payed specific attention in the development of "green" solutions in the metals industry, investing significantly in R&D for the design and discovery of new technologies and the optimization of existing ones in order to maximize environmental responsibility and energy efficiency and minimize energy consumption. Why? The environment and people's health on the one hand, the customers' profit and OPEX on the other. Breda holds a leadership position in the group when dealing with efficiency in electro-hydraulic systems, developed over the last years. Recently renewed awareness in energy-efficiency has been dictated by the trend in the U.S. Automotive industry motivating end-users to become more careful and demanding as far as this topic is concerned. However, fully understanding the actual strengths and weaknesses of the different solutions offered by the market is not always easy since safety, CAPEX, productivity, maintenance and equipment reliability also need to be considered. This present article will recount a comparative study of different state-of-the-art driving solutions for extrusion presses; a wide range of crucial aspects shall be taken into consideration and how specific requests made by the final user can bring about different strategic choices when investing in a new extrusion press or when revamping an existing one shall also be investigated. Having over 60 years' experience in extrusion technology, Breda aims to be a partner to guide end-users throughout the analysis of their specific needs and achieve the best-fit solution to improve energy efficiency and gain potential cost advantages.
