As the end product change generation and generation, the mainstream of the components processing technology changed
also. According to statistics, powder injection molding is one of the most popular technology at present.
Powder injection molding material has been developing from the early stage of the iron base, cemented carbide, ceramics,
etc is not sensitive to impurity content, is not very strict system function demand, carry out the high temperature nickel
base alloy, titanium and niobium material. Material also changed from layout type to the function type, such as heat sink
materials, magnetic materials and shape memory alloy. Material layout is also carried out from a single uniform layout to
the compound layout. Metal injection molding technology to complete a variety of different composition of powder
forming together, so you can get a sandwich composite layout. For example, 316L stainless steel and 17-4 ph alloy
composite, can complete the mechanical function of adjustable in succession.
An important development direction of the powder injection molding is closely related with the micro system
technology. In the category of related to micro system, such as electronic, chemical, medical equipment, equipment keep
miniaturizing, function complexing.
Micro injection molding technology is improved on the traditional injection molding technology. It is a forming
technology developed for small parts scale layout to 1 μm, basic technology together with the traditional injection
molding, but the material powder particle size is smaller. Using micro injection molding technology has now developed a
micro appearance 10 μm microfluidic device, scale between 350 μm to 900 μm stainless steel parts. Completed the
different material composition, the sintering or a total cohesion of compound layout, the magnetic non-conductors/nonmagnetic, conductor/micro composite parts.
