REPRINT FROM INDUSTRIAL HEATING

NET SHAPE PROCESSING
Using an Aqueous Based Injection Molding Binder in a Batch Furnace

Traditional applications for metal injection molding (MIM) have been small net shape parts (<25 grams) exhibiting design and economic benefits over wrought or cast components. The firearm, medical and electronics industries are prime producers/recipients of MIM components. Recent advances in binder systems and instrumentation for injection molding and sintering equipment are resulting in a dramatic expansion of MIM into new components and markets.

A new binder system for MIM (AlliedSignal PowderFlo™) that offers the ability to produce large, thick parts more commensurate with those produced by investment casting has been developed. A prime example is the application of MIM to aerospace components, which have demanding dimensional and mechanical properties.
