Successful research project: Chipless non-cutting production process without changing mechanical properties reduces material consumption

In the production of the Gesellschaft für Wolfram Industrie mbH, Traunstein/ Germany (www.wolfram-industrie.de) so far, approximately 26 to 40% of the sintered material was removed by cutting for the production of round rods. The proportion of waste increased at low diameters and led to a significantly increased consumption of raw materials. As part of a research project, from 2016 to 2018, the company developed a non-cutting production process for the production of tungsten-based heavy metal round rods. It reduces material consumption through its iterative rotary swaging annealing process.
