Rheological study of MIM water soluble binder system / Mohamad Fahmi Ghazali
Although many methods are used for characterization of Metal Injection Moulding (MIM) parts, but the process of metal injection molding (MIM) has provided an alternative for the manufacture to produce small and complex parts. MIM is an acronym for metal injection molding, a process for manufacturing...
