Abstract
It can be regarded as proven that the PM production of structural parts for the processing industry is a forming method involving minimum utilization of energy and material. In the present paper, data on energy consumption are examined using industrial examples for the individual stages in the process. These stages are the production of the raw material, shaping, sintering, and secondary forming. On the subject of single and double sintering, two examples are given in each case of the economies attainable through the use of PM processes, and some ideas for further reductions in energy consumption are put forward.
