Comparison between graphite and metallic lined MIM furnaces

This study reports on the parts quality and on the energy and resource consumption for both kinds of furnace for a typical batch type production process. The primary outcome achieved through the utilization of metallic lined Metal Injection Molding (MIM) furnaces is that highest densities of 7.9 g/cm^3 are achieved when using Hydrogen and a significant reduction in carbon content by 50 %. This advancement, however, is accompanied by a 30 % increase in the product's carbon footprint.
