Key Messages

In this paper, we study the concept of energy efficiency and specific energy consumption (SEC) of manufacturing processes.

We discuss the concepts of sustainable design of products, energy consumption based process planning and optimization which comprise the major challenges within the overall product lifecycle development activity. We show that energy consumption and SEC are important metrics that need to be measured for performing sustainable design and process planning.We present SEC results that we measured on a variety of injection molding and compression molding machines.
