Automatic control mode of powder molding hydraulic press;

Results show that the precursor powder prepared by spray-drying has hollow structure and average particle size of cessthan 20μm.

Dissolving ammonium vanadate(NH_4VO_3)and nanometer carbon in de-ionized water,the precursor powder was obtained through heating and drying,and nanometer vanadium carbide was prepared through reduction/carbonization of the precursor powder.

The precursor powder originated from the mixture of ammonium vanadate (NH4VO3) and nanometer carbon black.

91wt%N was prepared by metal powder injection molding(MIM),and the effect of solid solution treatment on the microstructure and mechanical properties was primarily studied.

Powder injection molding(PIM)is a kind of net-shape forming technology for manufacturing of small size and complex-shaped production.

The electronic package parts of Invar alloy were prepared by powder injection molding.

This paper introduces the current flow model of micro powder injection molding and the research development of powder material,binder and debinding,injection machine and mold,sintering and size controlled.

Introduce all sorts of techniques and their features of powder moulding,and present the design process of a powder moulding mold,and mold stuff,and give an application instance.
