The rheology of metal injection molding
Journal of Materials Processing Technology, 2003Abstract In this study, several readily available polymer binder systems were used to prepare Fe/Ni metal injection molding (MIM) feedstock. A Banbury intensive mixer and screw extrusion were used to achieve optimized feedstock, and the rheological properties of the resulting fluids were evaluated using a capillary rheometry.

Injection Molding of Metals and Ceramics
SAE Technical Paper Series, 1998<div class="htmlview paragraph">Powder injection molding (PIM) combines the processability of plastics and the superior material properties of metals and ceramics to form high performance components. The process comprises of several stages. Metal or ceramic powder and organic materials are combined into a homogeneous feedstock which is then ...

Powders for metal injection molding
Journal of the European Ceramic Society, 1998Metal injection molding (MIM) uses powders which differ considerably from the ceramics powders used for ceramic injection molding. Metal powders are hardly available in the sub-micron ranges that are almost standard in ceramics. The reason for this lies in the ductility and reactivity of the metals which make it difficult and very expensive to produce ...

Injection Molding of Liquid Metal by Harnessing Nonstick Molds
ACS Applied Materials & InterfacesThe fluid nature of liquid metals combined with their ability to form a solid native oxide skin enables them to be patterned in ways that would be challenging for solid metals. The present work shows a unique way of patterning liquid metals by injecting liquid metals into a mold. The mold contains a nonstick coating that enables the removal of the mold,

Effects of Process Parameters in Plastic, Metal, and Ceramic Injection Molding Processes
Korea - Australia Rheology Journal, 2011 Plastic injection molding has been widely used in the past and is a dominant forming approach today. As the customer demands require materials with better engineering properties that were not feasible with polymers, powder injection molding with metal ...

Applications for Metal Powder Injection Molding
2015Abstract Metal injection molding (MIM) is a metalworking technology that has its origins as a commercial technology only dating back to the early 1970s. This article explores why the MIM is the preferred solution for many fabricated components.

Designing for Metal Powder Injection Molding
2015Abstract This article commences with a discussion on the qualitative and quantitative criteria for metal injection molding (MIM), including production quantities, shape complexity, material performance, and cost. It discusses geometric factors, such as surface finish, component size, and mass range, which help to identify a component for

Advances in titanium metal injection molding
Powder Metallurgy and Metal Ceramics, 2007The approaches to production of titanium powder injection molded parts are reviewed. Historically, oxygen levels have been too high for structural use (particularly with the Ti-6Al-4V alloy). However, recent advances in starting powders, binders and sintering facilities now allow oxygen levels in the Ti-6Al-4V alloy to be controlled to about 0.2 wt ...
