Influence of Waste Plastic Binder on Sintered Properties of Injection Moulded M2 HSS / Rosniza Rabilah...[et al.]

Metal injection molding (MIM) is an effective way for producing small and complex-shape components in high production rates. Selection of binder and its removal in debinding process is a crucial stage in MIM process. In this study, the debinding and sintering characteristics of injection molded M2 H...
