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

Metal powder injection molding technology is a product of the penetration and intersection of many disciplines, such as plastic molding technology, polymer chemistry, powder metallurgy technology and metal materials science. It can use mold to inject molded blanks and rapidly manufacture high-density, high-precision, three-dimensional complex structural parts through sintering. It can quickly and accurately materialize design ideas into products with certain structural and functional characteristics, and can directly produce parts in batches, It is a new change in the manufacturing technology industry.

An important development direction of metal powder injection molding is closely related to microsystem technology. These micro system fields, such as electronic information, micro chemistry, metal injection molding MIM communication and medical care, metal injection molding MIM mobile phone accessories, metal injection molding MIM smart wear, metal injection molding MIM auto parts, require devices to be smaller and functions to be more complex, while metal powder injection molding technology provides the possibility of realization. Micro injection molding technology is a further development of metal powder injection molding technology. It is a molding technology developed for parts as small as 1 μ m. The basic process is consistent with traditional metal powder injection molding, but the particle size of raw material powder is smaller. A microfluidic device with a surface structure accuracy of 10 microns has been developed using micro injection molding technology, and stainless steel parts with dimensions of hundreds of microns, such as powder metallurgy micro gears, powder metallurgy small module gears and other precision structural parts; In addition, composite structures with different material compositions are realized, such as magnetic/non-magnetic and conductor/non-conductive micro composite parts.
