Powder Injection Molding (PIM) is a precision manufacturing process used for production of advanced composites. Mixing of polymeric binder with metal powders, molding of feedstock, de-binding of brown parts and sintering of green samples are four main steps of this process. In the present study, the compounds containing multi-component binder system and aluminum/ nano-alumina (0-9 wt.%) powders...

Metal injection molding (MIM) is a metal forming technique that combines powder metallurgy with plastic molding. MIM very efficient in manufacturing small and complex products large quantities. The process has four steps: mixing, debinding, molding, sintering. This research was conducted to determine the effect of variations Sn addition, temperature, holding time on density Al-PP after sinterin...

the present work reports and discusses the results of a 3d simulation of the injection molding process of a rubber compound that includes the mold flling stage and  material curing, using the computer code is developed in “udf” part of the fluent 6.3 cae software. the data obtained from a rheometer (mdr 2000) is used to characterize the rubber material in order to fnd the cure model parameters ...

This study focuses on fabrication of a micro plastic part using custom made vertical injection molding machine. Electrical discharge machining (EDM) and micro mechanical machining was used to fabricate micro shape cavity on aluminum mold. The mold was embedded with Polymethyl Methacrylate (PMMA) window to observe the behavior of plastic melt flow during injection. The custom made vertical injec...

injection molding is one of the most common processes which are used for manufacturing different plastic parts. this method includes 3 continuous steps: filling of the mold, cooling and driving the part out. a wide range of plastic and non-plastic materials can be used as raw material in this process. one of the most important advantages of this way of production is that it is very economic. in...
