Throughout industry, the Total Cost of Ownership (TCO) principle is a critical factor in decisions on procuring new machinery or plant. The actual procurement costs are not the only factor that a business must consider if it aims to manufacture competitively in the long term. It's equally important to factor in all the direct and indirect costs incurred before, during and after the procurement. This is the way to identify solutions that are most favorably priced and cost-effective. This principle also applies to joining and press-fit processes in industrial manufacturing: investments in electromechanical joining systems can pay off in the long run here – in terms of energy balance and maintenance expense as well as product scrap costs.
In May 2012, the University of Kassel published a study that compares the energy efficiency of hydraulic, pneumatic and electromechanical processes. The results highlight and emphasize the savings potential of electromechanical joining systems. With conventional hydraulic applications, the energy required is 4.4 times more than for electromechanical technology – and pneumatic processes actually use up to ten times more energy. With an electromechanical solution, greater efficiency means that savings of 77 percent are possible as compared to hydraulic systems; in relation to pneumatic applications, as much as 90 percent can be saved.
