Method for Evaluating and Identifying Energy-Efficient Process Chains for the Manufacturing of Press Hardening Tools Based on the Deming Circle

Abstract

In response to rising energy demand, climate change and resource scarcity, the German government has set guiding targets for the transformation of energy systems by 2050. One goal is to increase energy efficiency in order to halve the demand for energy. An important instrument for increasing energy efficiency and reducing energy costs is the energy audit. By determining how much energy is consumed in which areas of the company, it is possible to identify where there is potential for savings. This paper presents an evaluation method for identifying energy-efficient process chains for the production of press hardening tools. The evaluation method is based on the Deming Circle and is intended to serve as a supporting tool for the energy audit. The method enables the analysis and evaluation of energetic variables of a process chain and is designed for manufacturing companies.
