Because of micro powder injection molding technology has evolved from the traditional powder injection molding, so the technology of process steps and powder injection molding technology basic same, namely, feed preparation, preparation of raw material powder and binder uniform mixture), injection molding (will melt feeding filling into the mold cavity, be preformed billet), skim, completely remove the adhesive composition in the green, That is, the degreased blank is obtained) and sintering (degreased blank is heat treated to make it have certain density and mechanical properties). On the other hand, it also inherits three advantages of traditional POWDER injection molding technology, that is, low cost, complex shape and high performance. However, when the forming microstructure size down to micron level limits, of raw materials, equipment, injection forming and heat treatment process are put forward the more stringent requirements, the micro powder injection molding technology and the important distinction between the traditional powder injection molding technology, but also the meaning of micro powder injection molding technology research.
