Micro-powder injection molding
Journal of Materials Processing Technology, 2002Abstract Micro-system technology and related products will be used more widely in the new millennium. For their successful applications in various fields, e.g. in fluidic, medical, optical and telecommunications, economical mass production of the micro-components will be of great importance. Micro-powder injection molding (μPIM) reported in this work

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 ...

Micro Powder Injection Molding
Advanced Engineering Materials, 2000The availability of manufacturing processes suitable for medium and large-scale production of microscale devices is an important requirement for the economic success of microsystems technology. Powder injection molding is on its way to become such an established and economically viable process for manufacturing complex shaped metal or ceramic parts in ...

Powder Injection Molding of Niobium
Materials Science Forum, 2005Niobium and niobium-based alloys are used in a variety of high temperature applications ranging from light bulbs to rocket engines. Niobium has excellent formability and the lowest specific weight among refractory metals (Nb, Ta, Mo, W, and Re). Powder injection molding of niobium powder was investigated for efficiency of the process.

Overview of powder injection molding
Advanced Performance Materials, 1996Powder injection molding is a near net-shape technique suitable for the production of moderate to large volumes of small complex components of a wide range of materials such as ceramics, metals and hard metals. It combines the plastics injection molding technique with the power sintering techniques to produce high density parts at close tolerances. The

Analysis of Powder Segregation in Powder Injection Molding
Advanced Materials Research, 2011The powder injection molding (PIM) combines the thermoplastic and powder metallurgy technologies to manufacture intricate parts to nearly shape. The powder segregation is a special effect arising in PIM different from than the pure polymer injection.

Investigation of Properties of Powder Injection-Molded Steatites
Journal of Materials Engineering and Performance, 2011In this study, the mechanical and micro-structural properties of injection-molded steatites were investigated experimentally. Initially, steatite powders and binders of polyethylene glycol (PEG), polypropylene (PP), and stearic aside (SA) were mixed to prepare the feedstock. The mixing powders were granulated using the extruder.

Release behavior for powder injection molding in stereolithography molds
Rapid Prototyping Journal, 2001Adhesion has been measured between a powder injection molded (PIM) part and the stereolithography epoxy mold surrounding it after cooling. Analysis of release behavior suggests a link to the thermal properties of the mold material. Subsequent measurements of cooling in the part and at the part/mold interface are consistent with a one‐dimensional heat

Modeling of mold filling process for powder injection molding
Polymer Engineering & Science, 1991Abstract The mold filling process has been modeled for the injection molding of different polymer‐based binders and powder‐polymer mixtures. It is essentially a two dimensional non‐Newtonian fluid flow analysis in a non‐isothermal environment.

The Granular Model in Powder Injection Molding
Advanced Materials Research, 2012The granular model which is fit for discontinuous bodies is applied to powder injection molding. The powder is regarded as discrete particles which are immersed into binder. The powder three-dimensional flowing in powder injection molding has been simulated based PFC.
