The purpose of this paper is to document and discuss the latest advancements in the cemented tungsten carbide industry which include; new binder systems for improved corrosion resistance and smaller grain sizes that result in harder more wear resistant grades with increased edge strength. This paper will also discuss two (2) process improvements; the sinter-hip process which is the latest advancement in sintering technology that results in a cemented tungsten carbide product with a more uniform microstructure and the relatively new advanced technology of injection molding of tungsten carbide for cost reduction of complex components. The paper also highlights how these changes improve the tooling used on paper converting manufacturing lines that result in increased productivity and reliability in today’s mill operations.
