Micro injection molding products have broad application in actuators, sensors, pocket consumer products, weapons, aerospace, electronic assembly tools, oxygen analyzers, filters and medical care equipment.

The main obstacles that restrict the development of micro injection molding technology are the manufacture of precision micro mold, injection filling of narrow gap and the operation of small parts.

The production of this kind of high precision micro parts mold is much more accurate than the conventional mold,  need various types fine processing technology, such as lithography, electroforming, micro cutting, micro EDM, etc.. Using LIGA (German plate making, electroforming and injection molding) and other processes to produce by plastic disappearing method to solve these problems well.
