A Review of Metal Injection Moulding on WC-Co Cemented Carbide Comprised of Grain Growth Inhibitors (GGI)

This paper aims to provide a summary of metal injection moulding technologies utilising cemented WC-Co carbides comprised grain growth inhibitors (GGI). The advanced manufacturing (MIM) has the ability produce cement nanostructured carbides. In addition, nature feedstock plays crucial role when defect-free component at each point MIM phase, thus interactions between powder and binder combining, moulding, debinding are important be recognised. primary objective this analysis is investigate characterization form homogenous mixture. There five criteria classify features which include characteristics, composition, content ratio, mixing cycle, approaches palletization. Not only that, must meet specific criteria; higher loading with excellent flowability by rheological approaches. second goal research re-evaluate feedstock’s flow properties in relation activity terms index behaviour (n), activation energy (E), mouldability (α). practitioners have continued underestimate erratic product quality, including inadequate regulation, distortion, internal external defects. These defects can arise early processing phases, but often occur after sintering or debinding. also challenging provide. chapter includes description Explanations listed recommendations provided for these
