The function of the metal injection molding process is the induction function, including powder activity, bulk density, vibration density, compressibility, formability and sintering size variation. For some special applications, powders with other chemical and physical functions are also required, such as catalytic function, electrochemical activity, corrosion resistance, electromagnetic function, internal friction coefficient.

The function of metal injection molding reflects the nature of metal itself and the nature of individual particles and particles. Generally speaking, the function of metal powder is divided into chemical function, physical function and process function. Chemical properties refer to metal content and impurity content.

Metal injection molding refers to a group of metal particles with a size less than 1mm, including single metal powder, alloy powder and some refractory compound powder with metal properties. Metal injection molding injection molding production is mainly to meet the requirements of injection molding metal powder and adhesive, and then at a certain temperature using the appropriate way to powder and adhesive mixed evenly feed, granulation in injection molding molding.

Physical properties include uniform particle size and particle size dispersion, specific appearance and true density of powder, particle shape, external morphology and internal microstructure. The underlying functionality can be determined by specific standard testing methods.
