MIM offers increased applications for submicron WC-10%Co: Seco Tools is looking at the application of MIM for cutting tools using submicron WC-10%Co hardmetal

摘要

Submicron cemented carbides processed by the conventional powder metallurgy (PM) press and sinter route are already in use in a variety of cutting tool applications. The use of powder injection moulding (PIM) techniques would extend this rangebecause of the increased freedom of product design. This study by Johnny Bruhn of Seco Tools and Bjorn Terselius of Kristianstad University College examines the basic steps of PIM for a submicron WC-10%Co hardmetal system using a wax-polymer binder andstearic acid as a dispersant.
