The important development direction of metal powder injection molding is closely related to microsystem technology

Metal powder injection molding technology is a set of plastic molding technology, polymer chemistry, powder metallurgy technology and metal material science and the cross product of multi-disciplinary, such as using the mold to the injection molding and sintering ware rapid manufacturing high density, high precision, the three dimensional sticklebacks, structural parts, can rapidly and accurately materialized the ideas of design for products with a certain structure, function characteristics, and can be mass production directly from the parts, is a new manufacturing technology industry change.

An important development direction of metal powder injection molding is closely related to microsystem technology. These fields of Microsystems, such as electronic information, microchemistry, MIM communication and medical care, MIM mobile phone accessories, MIM intelligent wear, and MIM auto parts, require the miniaturization of components and more complex functions, while metal powder injection molding technology offers the possibility of realization. Micro-injection molding technology is a further development of metal powder injection molding technology, which is a molding technology developed for the size of parts as small as 1 micron. The basic process is consistent with traditional metal powder injection molding, but the raw material powder particle size is smaller. The micro-injection molding technology has developed a micro-fluid device with a surface structure accuracy of 10 microns, stainless steel parts with a size of hundreds microns, such as powder metallurgy miniature gear, powder metallurgy small module gear and other precision structural parts. Composite structures of different material components, such as magnetic/non-magnetic, conductor/non-conductor micro composite parts, are also realized.
